trading sessions explained: NY, London, and Asian session guide for futures traders
every futures trader knows the market is open nearly 24 hours a day — but not all trading sessions are created equal. most traders treat those hours as one continuous block, logging on whenever they're free and applying the same strategy no matter which session is active.
the problem with that approach is that different trading sessions produce completely different types of price action. the volume, the range, the types of setups that work — all of it changes depending on which window you're in.
futures trading sessions are built around global market handoffs. when one region's markets close, the next region picks up. each of the three trading sessions has its own personality, its own data, and its own opportunities. if you're not aware of which session you're trading in, you're missing context that directly affects your results.
in this guide, we're going to break down all 3 major futures trading sessions — what happens in each one, what the data shows, and which edgeful reports are most useful during each window. consider this your trading sessions explained from the data side.

what are trading sessions in futures trading
with trading sessions explained at a basic level, they're distinct time windows within the 24-hour futures market, each driven by a different region's participation. there are 3 major futures trading sessions:
- NY session — driven by US market participants. this is where the bulk of volume and range happens for US equity index futures (ES, NQ, YM, RTY)
- London session — driven by European market participants. this session overlaps with the Asian close and the NY pre-market
- Asian session — driven by markets in Tokyo, Sydney, Hong Kong, and Singapore. this is the quietest session for US futures
these trading sessions exist because global markets hand off to each other throughout the day. when Tokyo closes, London is opening. when London is winding down, New York is ramping up.
futures contracts — especially those tied to US indices — stay open through all of it, but the character of the price action changes depending on who's actively trading.
one thing that often confuses newer traders: trading sessions are not the same as ETH vs RTH. electronic trading hours (ETH) cover the full overnight + regular session. regular trading hours (RTH) are roughly 9:30 AM – 4:00 PM ET for equity index futures.
both the London and Asian trading sessions happen during ETH. if you want a full breakdown of that distinction, check out our ETH vs RTH guide.
understanding which trading session you're in — and what that session typically produces — is the first step to trading with better context.
the NY trading session (9:30 AM – 4:00 PM ET)
the NY session is where the majority of futures volume occurs. if you trade ES, NQ, or any US equity index futures, this is the trading session that matters most.
when the NY session runs
the official regular trading hours for equity index futures are 9:30 AM – 4:00 PM ET. but in practice, this trading session starts generating meaningful volume earlier than that.
- 8:00 – 9:30 AM ET — pre-market. economic data releases often hit at 8:30 AM (jobs reports, CPI, GDP). volume starts building here
- 9:30 AM — the equity cash market opens. this is when RTH officially begins and the opening range starts forming
- 4:00 PM ET — cash market close. volume drops off sharply after this point
most day traders focus on the 9:30 AM – 12:00 PM ET window. that's when the highest volume overlaps with the most data-backed setups within this trading session.
what happens during the NY session
the NY session is defined by a few key characteristics:
- peak volume. more contracts trade during the NY session than the London and Asian sessions combined for ES and NQ
- economic news releases. CPI, FOMC, jobs data, GDP — the market-moving reports almost always hit during the NY session window (typically 8:30 AM or 10:00 AM ET)
- the opening range forms. the first 5, 15, or 30 minutes after the 9:30 AM open establish the opening range — one of the most studied setups in futures trading
- the initial balance completes. the first 60 minutes of RTH define the IB range. once that range is set, the IB report tells you how often price breaks above or below it and continues
- institutional participation is at its peak. US-based funds, banks, and prop desks are all active during this window
NY session data: average range and key stats
the average range during the NY trading session is significantly larger than either the London or Asian session for US equity index futures.
over the last 6 months (14-day ATR, 9:30 AM – 4:00 PM ET):
ES (S&P 500 futures):
- NY session ATR: $95.71 — range exceeded 40.94% of the time (52 out of 127 days)
NQ (Nasdaq futures):
- NY session ATR: $449.26 — range exceeded 37.8% of the time (48 out of 127 days)
GC (gold futures):
- NY session ATR: $128.79 — range exceeded 31.5% of the time (40 out of 127 days)
according to edgeful data, the NY session exceeds its ATR more often than any other trading session for all three contracts. for ES, that's almost 41% of the time — meaning 4 out of every 10 days, the NY session alone produces a range that exceeds the 14-day average. here's an image directly from edgeful's reports page:
which edgeful reports work in the NY session
the NY session is where the majority of edgeful's reports are designed to perform:
- opening range breakout (ORB) — measures how often price breaks out of the opening range and follows through. the ORB report is filtered by timeframe (5, 15, 30 min) and session. this is a NY session setup — for a deeper dive, see our ORB strategy guide
- initial balance (IB) — tracks how often price breaks the first 60 minutes' high or low and continues. the IB by-levels and by-extension subreports show how far price travels after the break. see the full breakdown in our IB strategy guide
- session breakout — how often price makes new session highs or lows after a specific time. helps you decide whether to hold trades or take profit as the session matures
- power hour — data on the final hour (3:00 – 4:00 PM ET). edgeful's data shows that new session highs and lows during the last hour happen less frequently than most traders expect
who should trade the NY session
the NY session is the default trading session for most US-based futures day traders — and for good reason. it offers the most volume, the largest range, and the most data-backed setups.
if you can only trade one of the three futures trading sessions, this is the one the data supports.
- best for: day traders, scalpers, anyone focused on ES/NQ/YM/RTY, and traders who want access to the widest range of edgeful reports.
the London session (3:00 AM – 11:00 AM ET)
the London session is the bridge between the quiet overnight hours and the high-volume NY open. for US futures traders, it's often overlooked — but the price action during London directly affects what happens when New York opens.
when the London session runs
- 3:00 AM ET — the London session begins. European markets start coming online and volume picks up from overnight lows
- 8:00 – 9:30 AM ET — economic data releases hit (8:30 AM), pre-market volume ramps up. this window bridges London and the NY open
- 9:30 – 11:00 AM ET — the London-NY overlap. both sessions are active simultaneously. this is one of the highest-volume windows of the entire 24-hour cycle
what happens during the London session
the London session has a distinct character that separates it from both the overnight and the NY session:
- trend initiation. many of the directional moves that carry into the NY open start during London hours. the pre-market direction is often set between 3:00 and 9:30 AM ET
- FX crossover. the London session is the most active window for forex markets. this makes it especially relevant for gold (GC) and other currency-correlated futures. if you trade GC, the London session is not optional — it's where a significant portion of the daily range happens
- pre-market price discovery. the overnight high, overnight low, and developing value area are all being established during this window. these levels become reference points for NY session setups
- gap context. if the overnight session created a gap from the prior close, the London session is often where that gap starts to get addressed — or extends further before the NY open
London session data: average range and key stats
over the last 6 months (14-day ATR, 3:00 AM – 11:00 AM ET):
ES (S&P 500 futures):
- London session ATR: $93.71 — range exceeded 32.28% of the time (41 out of 127 days)
NQ (Nasdaq futures):
- London session ATR: $445.43 — range exceeded 28.35% of the time (36 out of 127 days)
GC (gold futures):
- London session ATR: $129.63 — range exceeded 21.26% of the time (27 out of 127 days)
GC's London session ATR ($129.63) is virtually identical to its NY session ATR ($128.79). that confirms what traders already know — gold is a global instrument with heavy European participation. the range doesn't drop off during London the way it does for ES and NQ.
which edgeful reports work in the London session
- session breakout (London filter) — the session breakout report can be filtered to London hours. this shows how often price breaks the London session high or low and continues — useful for understanding whether London moves tend to follow through or reverse at the NY open
- market session correlation — how does one session's direction predict the next? for example, when GC's London session closes green, the NY session follows green 81% of the time. this report connects what happened during earlier sessions to what's likely at the next open
- gap fill — if a gap formed overnight, the gap fill report tracks how often it gets filled. this setup spans sessions — the gap forms overnight and plays out at the NY open
who should trade the London session
the London session is most relevant for traders who are actively awake during those hours (European timezones) or who trade gold. for US-based equity futures traders, the London session is best used as context — understanding what happened pre-market helps you build a better bias for the NY open.
- best for: gold traders, traders in European timezones, traders who use pre-market context for NY session planning.
the Asian session (7:00 PM – 4:00 AM ET)
the Asian session is the quietest of the three trading sessions for US futures. volume is at its lowest, ranges are compressed, and directional moves are rare. but that doesn't mean it's irrelevant — what happens overnight sets the stage for everything that follows.
when the Asian session runs
- 6:00 PM ET (Sunday) — the CME Group futures market reopens for the week. this is the weekly open and can see gap moves from weekend events
- 7:00 PM ET — the Asian session begins (edgeful defines asia as 7:00 PM – 4:00 AM ET)
- 4:00 AM ET — the Asian session ends. the London session is already active (London starts at 3:00 AM ET), so there's an overlap window from 3:00 – 4:00 AM
what happens during the Asian session
- low volume and compressed range. the Asian session produces the smallest average range for US equity index futures. price tends to chop in a narrow band
- overnight positioning. institutional flow from Asian and Australian markets is focused on their own instruments — US futures are secondary during this window
- gap creation. the difference between the prior session close and where price trades during the overnight session creates the gap that plays out at the NY open. the bigger the overnight move, the bigger the potential gap fill setup
- Sunday open dynamics. the weekly open on Sunday evening can produce meaningful moves if significant news or events happened over the weekend. this is the one time the Asian session regularly sees elevated volatility for US futures
Asian session data: average range and key stats
over the last 6 months (14-day ATR, 7:00 PM – 4:00 AM ET):
ES (S&P 500 futures):
- overnight session ATR: $79.89 — range exceeded only 12.6% of the time (16 out of 127 days)
NQ (Nasdaq futures):
- overnight session ATR: $393.89 — range exceeded only 11.81% of the time (15 out of 127 days)
GC (gold futures):
- overnight session ATR: $127.96 — range exceeded 21.26% of the time (27 out of 127 days)
the compression is real for ES and NQ. the overnight ATR on ES ($79.89) is $16 lower than the NY session ($95.71), and it only exceeds its range 12.6% of the time — compared to 41% during the NY session. NQ shows the same pattern. if you're trading ES or NQ overnight with NY-sized targets, the data doesn't support it.
GC is the outlier again — the overnight ATR ($127.96) is almost identical to the NY session ($128.79). gold doesn't sleep the way equity index futures do.
which edgeful reports work in the Asian session
the Asian session is less about active trading and more about setting up the next session:
- gap fill — the overnight gap (distance from prior close to current price) is one of the most consistent setups in futures trading. the gap forms during the Asian/London session and resolves at the NY open. edgeful's gap fill report tracks how often these gaps fill, broken down by ticker, gap size, and direction. see our gap fill strategy guide for the full breakdown
- market session correlation — tracks how one session's direction predicts the next. if the Asian session closed red, does the London or NY session follow? this report gives you a data-backed answer for building a directional bias before the next session opens
who should trade the Asian session
most US-based retail futures traders should not actively trade the Asian session on ES or NQ. the range is too compressed and the volume is too thin to support most intraday strategies.
- the exception: traders in APAC timezones who are naturally awake during these hours, or traders who monitor the overnight session for context (gap levels, overnight range) to use in their NY session planning.
- best for: APAC-timezone traders, context monitoring, gap fill setup identification.
how trading sessions overlap — and why it matters
the transitions between trading sessions are some of the most interesting windows in the 24-hour cycle.
London → NY overlap (9:30 – 11:00 AM ET)
this is the highest-volume overlap of the day. the London session runs until 11:00 AM ET and the NY session starts at 9:30 AM — so for 90 minutes, both sessions are active simultaneously. this overlap often produces the strongest directional moves of the day.
if you're looking at the session breakout report for London, pay attention to whether London's high or low holds through the NY open. a London session high that breaks to the upside during the NY overlap is a different setup than one that reverses.
Asian → London overlap (3:00 – 4:00 AM ET)
this overlap between trading sessions is quieter. the Asian session runs until 4:00 AM ET and London starts at 3:00 AM — so there's a one-hour window where both are active. volume is still low, but you can sometimes see the first signs of the London trend starting to form here.
for most traders, this overlap is informational — not something you actively trade. but it helps explain why 3:00 – 4:00 AM ET can look like a transition period on the chart.
session comparison: which one fits your trading
here's a quick reference for how the three trading sessions compare:
NY session (9:30 AM – 4:00 PM ET):
- volume: highest
- average range: largest (ES, NQ)
- best reports: ORB, IB, session breakout, power hour
- best for: day traders, scalpers, US equity index focus
London session (3:00 AM – 11:00 AM ET):
- volume: moderate
- average range: meaningful for GC, moderate for ES/NQ
- best reports: session breakout (London filter), market session correlation
- best for: gold traders, European timezones, pre-market context
Asian session (7:00 PM – 4:00 AM ET):
- volume: lowest
- average range: smallest (ES, NQ)
- best reports: gap fill, market session correlation
- best for: APAC timezones, overnight context monitoring
here's the full ATR comparison across all 3 sessions (14-day ATR, last 6 months):
ES: overnight $79.89 → London $93.71 → NY $95.71
NQ: overnight $393.89 → London $445.43 → NY $449.26
GC: overnight $127.96 → London $129.63 → NY $128.79
for ES and NQ, the range increases as you move from overnight to NY. for GC, it stays virtually flat — gold moves regardless of session.

how to mark sessions on your charts
once you understand the sessions, the next step is making them visible on your charts. this is where edgeful's trading sessions indicator for TradingView comes in.
the indicator draws session boundaries directly on your chart — so you can see at a glance which session you're in, where the session high and low are, and when the transitions happen. this is especially useful for:
- identifying when you're trading in a low-volume window vs. a high-volume window
- spotting session highs and lows as potential support and resistance levels
- avoiding trades during dead zones (late Asian session, midday lull)
you don't need to memorize session times. just mark them on your chart and the context becomes obvious.
common mistakes with trading sessions
mistake 1: treating all hours the same
if you're using the same strategy across trading sessions — the same stop size and the same targets at 11:00 PM ET that you use at 10:00 AM ET — the data is not on your side. each session has a different average range. your targets and stops should reflect the session you're in.
mistake 2: trading the Asian session with NY session expectations
this is the most common version of mistake 1. a trader sees a "setup" at 8:00 PM ET, enters with a 20-point target on ES, and wonders why it never hits. the average range during the Asian session is a fraction of the NY session. the data doesn't support those targets during those hours.
mistake 3: ignoring the London → NY handoff
what happens between 2:00 and 9:30 AM ET is not just noise. the levels established during the London session — the overnight high, the overnight low, the pre-market direction — directly feed into NY session setups like gap fills, ORB, and IB.
traders who only start looking at the chart at 9:30 AM are missing the context from the London session (which has been running since 3:00 AM). you don't have to trade London hours, but you should know what happened during them.
key takeaways
- futures trading sessions are 3 distinct windows — NY, London, and Asian — each with different volume, range, and setups
- the NY session (9:30 AM – 4:00 PM ET) produces the largest range and highest volume for US equity index futures — it's where ORB, IB, and session breakout reports are most useful
- the London session (3:00 AM – 11:00 AM ET) is critical for gold (GC) and sets the pre-market direction for the NY open
- the Asian session (7:00 PM – 4:00 AM ET) is the quietest for US futures — best used for context and gap fill setup identification, not active day trading
- the London → NY overlap (9:30 – 11:00 AM ET) is one of the highest-volume windows of the entire 24-hour cycle
- day of week matters too — Thursday/Friday produce the largest range while Monday is the most compressed. ES Thursday NY range ($74.31) is 25% larger than Monday ($59.21). see our day of week trading strategy guide for the full data
- mark sessions on your charts using the trading sessions TradingView indicator so you always know which window you're in
