technical analysis: how to read charts and make better trades
technical analysis is one of those topics where everyone has an opinion. some traders swear by it. others call it astrology for finance.
the truth? technical analysis works — but only when you know what to look for and how to validate it with real data. the problem is that most technical traders stop at the chart. they learn to spot patterns, draw lines, and overlay indicators... but they never check whether those patterns actually play out at a rate worth trading.
that's the gap this guide fills. we're going to cover technical analysis from the ground up — chart types, patterns, indicators, moving averages, candlestick formations, volume, risk management — and then connect it all to the approach that actually moves the needle: combining chart reading with historical data.
this is a long one. use the table of contents to jump around if you're already past the basics.

what is technical analysis
technical analysis is the study of price and volume data to identify patterns and make trading decisions. instead of looking at a company's earnings, revenue, or management team, technical traders focus entirely on what the chart is telling them.
the core assumption is simple: price reflects all available information. everything — earnings reports, news events, Fed announcements, market sentiment — is already baked into the price. so if you can read the price accurately, you don't need to dig through financial statements.
this idea goes back to Charles Dow in the late 1800s. Dow Theory laid the foundation for what we now call technical analysis of stocks and futures. the principles have evolved over the last century, but the core logic hasn't changed: price moves in trends, patterns repeat, and you can use that historical behavior to inform your next trade.
today, technical analysis trading is the dominant approach for day traders and short-term traders. if you're trading intraday futures — ES, NQ, GC, CL — you're almost certainly using some form of TA, whether you realize it or not. every time you look at a chart and make a decision based on what price is doing, that's technical analysis.
the real question isn't whether technical analysis works. it's whether you're using it in a way that gives you an actual edge.
technical analysis vs fundamental analysis
this is one of the most common debates in trading. technical analysis looks at price and volume. fundamental analysis looks at a company's financials, economic data, and business health.
here's a quick comparison:
- what they analyze
- TA: price action, volume, chart patterns, indicators
- fundamental: earnings, revenue, P/E ratios, economic data, management quality
- time horizon
- TA: short to medium term (intraday to weeks)
- fundamental: medium to long term (weeks to years)
- tools used
- TA: charts, indicators, oscillators, pattern recognition
- fundamental: financial statements, SEC filings, economic reports
- best for
- TA: day trading, swing trading, timing entries and exits
- fundamental: long-term investing, value investing, portfolio allocation
for most day traders, technical analysis of stocks and futures is the primary tool. when you're holding a position for minutes or hours, a company's quarterly earnings don't matter as much as what price is doing right now.
that said, most experienced traders use both to some degree. even chart-focused traders pay attention to the economic calendar. knowing when a Fed announcement is coming gives you context for why the chart might be acting differently than usual. and long-term investors often care about things like growth vs value stocks — a distinction that matters more in fundamental analysis than TA.
for a deeper look at how these two approaches compare, check out our full breakdown on technical vs fundamental analysis.
the core principles behind technical analysis
TA rests on 3 foundational ideas. every indicator, every pattern, every chart study traces back to these.
price discounts everything
this is the efficient market hypothesis applied to charts. the idea is that all known information — public and private — is already reflected in price. you don't need to know why price is moving. you just need to read where it's moving and how fast.
for chart traders, this is liberating. you don't need to be an economist or a Wall Street analyst. you need to be a good chart reader.
prices move in trends
markets don't move randomly. they trend — up, down, or sideways. a core job of TA is identifying the current trend and trading in the direction of that trend.
this sounds simple, and it is. but simple doesn't mean easy. the hard part is identifying when a trend is starting, when it's ending, and when you're just looking at noise.
history tends to repeat
this is the principle that makes chart patterns and candlestick formations valuable. human psychology doesn't change. fear and greed drive the same behaviors cycle after cycle. so patterns that have played out hundreds of times before have a meaningful chance of playing out again.
but here's where most chart traders stop short: they see a pattern and assume it'll work. they don't check how often that pattern actually follows through. they don't look at the win rate across different tickers, timeframes, or sessions. that's the difference between reading a chart and actually using the data.
does technical analysis actually work?
honestly? it depends on how you use it. if you're drawing random trendlines and expecting them to hold because a YouTube video said they would — no, it's not going to work consistently.
but if you're using TA as a framework, combining it with data on historical behavior, and managing your risk properly — then yes, it works. it's not magic. it's a structured way to read the market and make decisions based on something other than gut feel.
chart types every trader should know
before you can do any technical analysis trading, you need to understand the charts you're reading.
line charts
the simplest chart type. it connects closing prices with a single line. line charts are useful for seeing the overall trend at a glance, but they strip away a lot of information.
you can't see opening prices, highs, lows, or the range of each session.
most traders don't rely on line charts as their primary view. they're good for quick reference, but that's about it.
bar charts (OHLC)
bar charts show 4 data points per period: open, high, low, and close. each bar is a vertical line with small horizontal ticks on either side — the left tick is the open, the right tick is the close.
bar charts were the standard for decades. some old-school traders still prefer them. they give you more information than line charts, but they're harder to read at a glance compared to the next option.
candlestick charts
candlestick charts are the standard for most traders today. they show the same OHLC data as bar charts but use color-coded "bodies" and "wicks" that make it much easier to read price action quickly.
a green (or white) candle means the close was above the open — price went up. a red (or black) candle means the close was below the open — price went down. the body shows the range between open and close, and the wicks show the high and low.
candlestick charts became popular because they're visual. you can spot patterns, momentum shifts, and price rejection faster than with any other chart type. if you're doing stock technical analysis or futures trading, this is almost certainly what you're looking at.
support and resistance: the foundation
if you learn one thing from TA, make it support and resistance. everything else — indicators, patterns, moving averages — is built on top of this.
support is a price level where buying pressure tends to step in and prevent price from falling further. resistance is a price level where selling pressure tends to step in and prevent price from rising further.
you can identify these levels in a few ways:
- horizontal levels: price areas where the market has reversed multiple times in the past. the more times price bounces off a level, the more significant it becomes
- trendlines: diagonal lines connecting higher lows (uptrend support) or lower highs (downtrend resistance)
- dynamic support/resistance: moving averages that price tends to respect — like the 20 or 50 period moving average acting as a floor or ceiling
the reason support and resistance matter so much is that they give you a framework for making decisions. instead of asking "should i buy here?" you can ask "is price near a level that has historically held?" that's a much more useful question.
one thing to keep in mind: support and resistance aren't exact prices. they're zones. price might bounce at 4,500 one day and 4,505 the next. thinking in zones instead of exact numbers will save you a lot of frustration.
trend analysis: reading market direction
one of the most important skills in trading is reading the trend. most technical traders have heard the phrase "the trend is your friend" — and there's a reason it's become a cliché. trading in the direction of the trend is one of the simplest edges you can have.
how to identify trends
- uptrend: price is making higher highs and higher lows. each pullback holds above the previous low, and each push higher takes out the previous high
- downtrend: price is making lower highs and lower lows. each rally fails to reach the previous high, and each drop takes out the previous low
- sideways / range-bound: price is bouncing between a support and resistance zone without making meaningful new highs or lows
why trends matter
when you can identify the trend, you already know which direction the data favors. in an uptrend, long setups have a higher win rate than short setups. in a downtrend, the opposite is true. this is basic stuff, but a lot of traders ignore it.
the mistake most traders make is trying to call reversals instead of riding the trend. they see a market that's been going up for days and assume "it has to come down." that's not analysis — that's a guess. the data doesn't care about your expectations.
trend analysis gets even more powerful when you combine it with actual historical data — something we'll cover later in this guide.
chart patterns that matter
chart patterns are one of the most visually intuitive parts of TA. you're looking at shapes that price forms on a chart and using those shapes to anticipate what happens next.
continuation patterns
these suggest the current trend is likely to continue:
- flags and pennants: short consolidation periods within a strong trend. price pauses, forms a small range, then continues in the same direction
- triangles: ascending triangles (higher lows pressing into flat resistance), descending triangles (flat support with lower highs pressing down), and symmetrical triangles (converging trendlines)
reversal patterns
these suggest the current trend might be ending:
- head and shoulders: 3 peaks — a higher middle peak with 2 lower peaks on either side. when the "neckline" breaks, it's a bearish reversal pattern. the inverse version is bullish
- double tops and double bottoms: price hits the same level twice and reverses. double tops are bearish. double bottoms are bullish
the key with technical analysis chart patterns is that they're not guarantees. a head and shoulders pattern doesn't mean price will definitely reverse. it means there's a historical tendency for it to reverse — and the strength of that tendency depends on the context: the ticker, the timeframe, the volume, and the broader trend.
this is where most TA falls apart. traders learn patterns from a textbook, see them on a chart, and assume they'll play out. but they never check the actual numbers. how often does this pattern lead to a successful trade on ES? on NQ? during the NY session? those questions matter, and most traders never ask them. for a deeper breakdown of all 9 major patterns — including which ones have real backtested data and which are purely visual — see our day trading chart patterns guide.
indicators and oscillators
indicators are mathematical calculations applied to price and volume data. they're designed to give you additional context beyond raw price action.
there are hundreds of indicators out there. most of them are variations of the same few ideas. here are the ones that actually matter.
RSI (relative strength index)
RSI measures the speed and magnitude of recent price changes on a scale from 0 to 100. readings above 70 are considered "overbought" and readings below 30 are considered "oversold."
the mistake most traders make with RSI is treating those levels as automatic buy/sell zones. just because RSI hits 70 doesn't mean price is about to drop. in a strong uptrend, RSI can stay overbought for a long time.
the real value of RSI is context. when RSI diverges from price — price makes a new high but RSI doesn't — that's a warning sign worth paying attention to. for a complete breakdown of how to actually use RSI with data, check out our RSI indicator trading guide. and for a deeper look at what those overbought/oversold levels actually mean and when they're reliable, see our overbought vs oversold guide.
MACD (moving average convergence divergence)
MACD tracks the relationship between 2 moving averages — typically the 12 and 26 period EMAs. it shows momentum shifts and potential trend changes.
the MACD line crossing above the signal line is traditionally a bullish signal. crossing below is bearish. but like RSI, context matters more than the signal alone.
MACD is most useful as a trend confirmation tool, not a standalone trigger. we cover this in depth in our MACD indicator guide.
bollinger bands
bollinger bands consist of a middle band (usually a 20-period SMA) with an upper and lower band set 2 standard deviations above and below. they expand when volatility increases and contract when it decreases.
bollinger bands are useful for identifying when price is extended relative to its recent range. a "squeeze" — when the bands contract tightly — often precedes a big move. the challenge is knowing which direction that move will go.
stochastic oscillator
the stochastic oscillator compares a closing price to a range of prices over a specific period. like RSI, it oscillates between 0 and 100, with readings above 80 considered overbought and below 20 considered oversold.
the stochastic is popular among day traders because it's responsive to short-term price changes. it's most useful in range-bound markets where overbought and oversold levels are more meaningful. for a complete walkthrough including how to customize settings and combine it with other data, see our stochastic oscillator guide.
moving averages: the backbone of technical analysis
if there's one TA tool that every trader uses, it's the moving average. it smooths out price data to help you see the trend more clearly.
SMA vs EMA
- SMA (simple moving average): takes the average of closing prices over a set period. equal weight to all data points
- EMA (exponential moving average): gives more weight to recent prices. reacts faster to new data
which one is better? it depends on what you're doing. EMAs are generally better for short-term trading because they respond faster to price changes. SMAs are smoother and better for identifying longer-term trends.
for a detailed comparison with actual data behind the performance differences, check out our EMA vs SMA complete guide.
the most common periods
- 9 EMA: fast-moving, used by day traders for short-term momentum
- 20 SMA/EMA: the "standard" short-term trend line. many traders use this as their primary reference
- 50 SMA: the medium-term trend. institutional traders watch this level
- 200 SMA: the long-term trend. widely considered the dividing line between a bull market and a bear market
golden cross and death cross
a golden cross happens when the 50-period moving average crosses above the 200-period moving average. it's traditionally seen as a strong bullish signal.
a death cross is the opposite — the 50 crosses below the 200. bearish signal.
both of these are lagging indicators by nature. by the time a golden cross or death cross forms, a significant move has usually already happened. they're better used as confirmation of a trend that's already underway rather than a timing tool for entries. we break down the full backtested data (66 years, 79% win rate) in our golden cross complete guide, and the bearish mirror signal in our death cross guide.
the real question with any moving average crossover — whether it's a golden cross or a 9/20 crossover — is: how often does it actually lead to a profitable move? that's where historical data comes in, and it's the kind of question most traders never think to ask.
candlestick patterns: reading price action
candlestick patterns are the language of price action. each candle tells you a story about the battle between buyers and sellers during that period. when specific candles form in specific contexts, they can give you a read on what's likely to happen next.
single-candle patterns
- hammer: small body at the top of the candle with a long lower wick. shows up at the bottom of a downtrend and suggests buyers stepped in. the longer the lower wick relative to the body, the stronger the rejection of lower prices
- shooting star: the inverse of a hammer. small body at the bottom with a long upper wick. shows up at the top of an uptrend and suggests sellers stepped in
- doji: open and close are nearly the same, creating a cross or plus sign shape. shows indecision. a doji after a strong trend can signal a potential reversal
multi-candle patterns
- engulfing pattern: a candle that completely engulfs the body of the previous candle. a bullish engulfing (green candle engulfing a red candle) at the bottom of a downtrend is one of the strongest reversal patterns. bearish engulfing is the opposite
- morning star / evening star: 3-candle patterns. a morning star is a large red candle, followed by a small-bodied candle (indecision), followed by a large green candle. it signals a potential bottom. evening star is the bearish version
the value of candlestick patterns depends heavily on context. an engulfing pattern at a key support level is much more meaningful than one in the middle of nowhere. the same pattern at different price levels, on different tickers, in different sessions can have wildly different win rates.
for a complete breakdown including which patterns actually have the highest follow-through rates, see our candlestick patterns for day trading guide.
volume: the confirmation signal most traders ignore
volume is one of the most underused tools in stock technical analysis. it tells you how many shares or contracts traded during a given period — and it's the closest thing you get to seeing conviction behind a price move.
why volume matters
price can lie. volume usually doesn't. here's what i mean:
if price breaks above a resistance level on heavy volume, that breakout has conviction. there are real buyers stepping in and pushing price higher. but if price breaks out on thin volume? that's suspect. there's no real force behind the move, and it's more likely to reverse.
volume confirmation
the basic framework:
- breakout + high volume = strong confirmation. the move is more likely to continue
- breakout + low volume = weak confirmation. treat it with skepticism
- trend + increasing volume = the trend is healthy. buyers (or sellers) are in control
- trend + decreasing volume = the trend is losing steam. a reversal or consolidation might be coming
price-volume divergence
this is one of the more powerful reads in TA. when price is making new highs but volume is declining, it means fewer and fewer participants are driving the move higher. that divergence often precedes a pullback or reversal.
the same applies in reverse — price making new lows on declining volume can signal that sellers are exhausted and a bounce is coming.
volume won't tell you exactly when to enter or exit. but it gives you a layer of confirmation that most traders completely skip. when you combine volume with support/resistance, trend direction, and pattern recognition, you're building a much more complete picture.
position sizing: where technical analysis meets risk management
this is the section that most TA guides skip — and it's arguably the most important one.
you can have the best chart analysis in the world. you can spot every pattern, use the right indicators, and nail your entries. but if your position sizing is wrong, none of it matters.
the 1-2% rule
most experienced traders risk no more than 1-2% of their account on any single trade. that means if you have a $50,000 account and you're risking 1%, your maximum loss per trade is $500.
this sounds conservative. it is. and that's the point. the goal of risk management is making sure no single trade can blow up your account.
connecting TA to position sizing
here's where it all ties together. your chart work tells you where to enter and where to place your stop. the distance between your entry and your stop determines your risk per share or per contract.
and that risk, combined with the 1-2% rule, determines how many shares or contracts you trade.
the formula is straightforward:
- position size = (account risk) / (per-share/per-contract risk)
- example: $500 max risk / $5 per share risk = 100 shares
if you're doing this correctly, your chart work tells you both where to trade and how much to trade. the 2 are inseparable. position sizing becomes part of your analysis — not something you figure out after the fact.
the data-driven approach to technical analysis
here's where we pull it all together.
everything we've covered so far — chart types, support and resistance, trends, patterns, indicators, moving averages, candlestick formations, volume, position sizing — is what most traders consider "technical analysis." and all of it is valuable.
but there's a step that most traders miss: validating what you see on the chart with actual historical data.
the traditional approach vs the data-driven approach
the traditional TA approach looks like this:
- you spot a pattern on the chart
- you enter the trade based on what you've learned that pattern "should" do
- you hope it works out
the data-driven approach adds a critical step:
- you spot a pattern on the chart
- you check what the data says about that pattern — how often it follows through, on which tickers, in which sessions, over what timeframes
- you make a decision based on the actual numbers, not on a textbook definition
- you size the trade based on the data, not on gut feel
that extra step — checking the data — changes everything.
what this looks like in practice
say you're looking at NQ and you spot a gap down in the morning. traditional TA might tell you to look for a gap fill trade. but does the gap actually fill? how often?
according to edgeful data, a gap fill occurs on NQ 53-59% of the time from September to March, 2026:
it's not a guess — this data is based on hundreds of datapoints over the last 6 months.
now compare that to just drawing a line on a chart and hoping price fills the gap. one approach is based on data. the other is based on a feeling.
this is the difference between using technical analysis as a starting point and using it as the answer. TA gives you the framework. data gives you the edge.
where edgeful fits in
edgeful is built for exactly this approach. it turns historical market data into reports you can use to validate your chart work. instead of guessing whether a setup is worth taking, you can see the actual historical performance — filtered by ticker, timeframe, session, and market conditions.
the work is still on you. you still need to learn the fundamentals, know how to read charts, and develop a process. edgeful doesn't replace that. but it adds the data layer that most technical traders are missing.
it's the difference between "i think this pattern works" and "i know this pattern hits 60-70% of the time on ES in the NY session over the last 6 months."
that kind of context changes how you trade. it changes your confidence. and it changes your results — assuming you put in the time to learn the data and customize the reports to fit your style.
