how to set a stop loss: the data-backed approach that prevents blowing accounts
you know that feeling when you get stopped out by a few ticks, only to watch price reverse and go exactly where you thought it would... without you?
we've all been there. the horrible feeling of being right about the direction but wrong about how to set a stop loss properly.
here's the thing — this happens consistently when you're setting stops based on how you feel instead of what the market actually does. most traders set stops thinking "I can afford to lose $200 on this trade" or "I'll risk 1% of my account." these approaches ignore actual market behavior.
today I'm going to show you how to set a stop loss using 3 data-driven reports that tell you exactly where price typically continues before reversing. no more guessing, no more getting stopped out right before your trade works.

why traditional stop loss methods fail traders
the reason so many traders struggle isn't because they don't have profitable strategies. it's because they don't know how to set a stop loss properly.
most approaches to stop loss placement are purely emotional:
emotional stop loss methods:
- "I can afford to lose $200 on this trade"
- "I'll risk 1% of my account and hope it works"
- "I'll use a $50 stop because that feels right"
all of these ignore what the market actually does. they're based on your comfort level, not market behavior.
what successful traders do differently:
traders who consistently pass funded challenges use data to determine how to set a stop loss. they check continuation patterns before entering trades.
for example: you're trading a gap fill on ES. price gaps up 23 points and you want to short for the fill.
emotional trader: "I'll risk $300, so I'll put my stop 6 points above my entry" — without checking how often price moves past 6 points when it spikes on open.
data-driven trader: checks gap fill by spike report — shows ES continues an average of 8.20 points in the direction of the gap up before reversing to fill. sets stop just outside the 8.20 range.
which approach seems more logical?
the 3 reports that solve stop placement forever
these reports are based on thousands of data points telling you exactly how price moves before reversing:
- gap fill by spike - shows average continuation in the gap direction before fills
- outside days by spike - shows continuation after opening outside yesterday's range
- initial balance by retracement - shows typical retracement levels after breakouts
unlike traditional stop loss placement methods that rely on arbitrary dollar amounts, these reports give you actual market data for how to set a stop loss in different scenarios.
gap fill by spike: exact continuation data
the gap fill by spike report measures how far price continues in the gap direction before reversing to fill.
key data for YM:
- gaps up continue an average of $69.88 before reversing (last 6 months)
- gaps down continue an average of $92.77 before filling
this data completely changes how to set a stop loss for gap trades. instead of using random levels, you base stops on actual continuation patterns.
how to use gap fill data for stop loss placement:
- check the average spike for your ticker
- use the what's in play dashboard to see current spike levels with live data
- wait for majority of spike to play out, add 10-20% buffer
- place your stop above that level
real example: YM gaps up $163, average spike is $68.46. if you're entering on the open, you'd set your stop around 70 points above your short entry — not some random $50 level that ignores market behavior.
important note: spike data is an average, so sometimes continuation will be more. give the spike breathing room to account for this variation when determining how to set a stop loss.
outside days by spike: continuation before reversal
an outside day occurs when price opens completely outside yesterday's range (above yesterday's high or below yesterday's low).
the outside days by spike report only tracks days that reversed and filled back to the prior session's range. if price continues in the gap direction, that data isn't counted.
key data for YM:
- bullish outside days: average $68.56 continuation upward before reversing
- max spike: $245
how to use outside day data for stop loss decisions:
when you're trading outside day reversals, your stop needs to account for initial continuation.
example: outside day gaps up to $45,286, you're looking to short for reversal:
- check outside days by spike report
- see average continuation is $68.56
- place stops around $75-80 from open (giving spike room)
- or wait for spike to play out, then enter with stops at technical levels
this approach to how to set a stop loss prevents getting knocked out during normal price continuation before the reversal begins.
initial balance by retracement
the initial balance is the first hour of trading (9:30-10:30 ET). the IB by retracement report checks how far price retraces back into this range after breaking out.
retracement statistics for YM (last 6 months):
- 10% retrace level hit 65% of the time
- 55% retrace level hit 20% of the time
- 75% retrace level hit 8.16% of the time
since we're focused on how to set a stop loss, the 55% retrace level is excellent for stop placement because price only touches this area 20% of the time on single breakout days.
how to use IB retracement for stop loss placement:
- if long above IB high, place stop below low probability retracement level
- if short below IB low, place stop above low probability retracement level
this separates amateur breakout traders from professionals. while others use arbitrary stops, you're placing stops based on actual retracement probabilities.
step-by-step process for data-backed stops
here's exactly how to set a stop loss using data instead of emotions:
the 4-step process:
- identify your setup (gap, outside day, IB break, etc.)
- check relevant spike/retracement data using edgeful reports
- add 10-20% buffer to the average continuation
- place stop beyond that level
example scenario: outside day that also creates a gap
check both outside days by spike AND gap fill by spike reports. use the larger of the two averages for your stop placement.
position sizing connection:
once you know where your stop should be (based on data), size your position accordingly.
if data says you need $100 of room and you want to risk $300 total:
- trade 3 contracts maximum
- don't force 10 contracts with $30 stop just because you want to risk $300
proper position sizing = total risk ÷ data-backed stop distance
this is fundamentally different from traditional methods of how to set a stop loss that start with position size and work backwards.
common stop loss mistakes that destroy accounts
- mistake 1: using data from wrong timeframes match your report timeframe to current market conditions. if trading in volatile periods, check 1-month data rather than 6-month averages.
- mistake 2: ignoring multiple report signals if gap fill AND outside day both suggest $80 continuation, don't use a $40 stop.
- mistake 3: reverting to emotional stops after one winner data works over time, not on every single trade. stick to the process.

frequently asked questions
how do I set a stop loss for gap trades specifically?
check the gap fill by spike report for your ticker. YM gaps up continue average $69.88 before reversing. add 10-20% buffer and place stop above that level rather than using arbitrary amounts.
what's the difference between data-backed stops and percentage stops?
percentage stops are based on your account size or comfort level. data-backed stops are based on actual market continuation patterns. if data shows price typically continues $80 before reversing, your stop should account for that regardless of percentage.
should I adjust my stop loss approach during high volatility?
you can — but this adds another layer of complexity to your process. if you can't put data behind it, don't do it.
how often should I check these reports?
daily during pre-market preparation. Market conditions change, so recent data (1-3 months) often more relevant than longer timeframes for current stop placement.
can I use this approach with algorithmic trading?
absolutely. many traders use these reports to trade our automated trading strategies right now!
key takeaways
learning how to set a stop loss properly isn't about finding "perfect" levels. it's about using actual market behavior instead of random numbers based on feelings.
remember these principles:
- base stops on continuation data, not account percentages
- different setups require different stop approaches
- add buffers to average data to account for variation
- size positions based on data-required stop distance
- check current market conditions regularly
the fundamental shift: stop asking "how much can I afford to lose?" start asking "how far does price typically continue before reversing?"
the market doesn't care about your account size or comfort level. but it does move in predictable patterns you can measure and use to your advantage.
next time you're about to place a stop, ask yourself: "am I basing this on data, or emotions?"
