Best Bollinger Band Settings: 315 Backtests, Fade vs Breakout

Bollinger Bands are a moving average with a band above and below it, set at some multiple of how much price has been varying. Most of the price action stays inside that envelope, which leaves two opposite ways to trade it: fade the band, betting that a touch snaps back, or follow the break, betting that price pushing outside keeps going.

Which one is right depends on who you ask. So we measured both, on the same pair, over the same period, paying the same costs.

For 2025 (1 January to 31 December) on USD/JPY, seven periods crossed with five deviations, plus four choices of where the fade takes profit, gives 140 fade settings, run separately for the long and the short side, and 35 breakout settings — 315 in all. Each was run on three timeframes, and the whole grid was run again on 2024.

The answer first. On the hourly chart, the fade averaged a 60.1% win rate and came through both years in only 28 of 140 settings; the breakout averaged 40.4% and came through in 23 of 35. Selling the upper band did worse still: zero settings out of 140 were profitable in both years on either the 15-minute or the hourly chart. Ranked by win rate, the order reverses.

What the bands are measuring

The middle line is a simple moving average (period). The bands sit above and below it at a multiple of the standard deviation of closes over that same period (deviation).

The usual claim is that 1σ holds about 68% of the action and 2σ about 95%. That is what a normal distribution would do. Counting the actual bars gives something else — here are the 6,226 hourly USD/JPY closes of 2025 against a 20-period band:

Deviation	Closes finishing inside
1σ	45.0%
1.5σ	70.4%
2σ	87.1%
2.5σ	95.1%
3σ	99.1%

Every band holds less than the textbook says. At 2σ, roughly one bar in eight closes outside. A fade built on "price rarely goes there" is going to meet price out there more often than the assumption allows.

The bands themselves are a ruler that stretches with the market — wide when it is moving, narrow when it is not. The same 2σ is a different number of pips on different days.

There are two knobs, or three for the fade.

Knob	What raising it does
Period	The middle line dulls. Fewer touches
Deviation	The bands move further out. Fewer touches and fewer breaks
Take-profit deviation (fade only)	Puts the far band further away. Fewer trades, each held longer

The counts bear it out. Averaged over the fade-long settings on the hourly chart in 2025, a period of 10 traded 369 times a year and a period of 50 traded 54. By deviation it runs 249 trades at 1σ down to 79 at 3σ. Every knob is partly a trade-count knob, which is where the costs come in later.

How to put them on a chart

Bollinger Bands ship with every platform.

Platform	Steps
MT4 / MT5	Pick Bollinger Bands from the indicator list and set the period and deviation
TradingView	Add Bollinger Bands from the indicator search and set the period and deviation
Browser (Formiq)	Built in; the backtest side switches between fading a touch and following a break with a trigger

Drawing them is the same everywhere. The decision that matters is whether your rule fires on a touch or on a break — and this article treats those as two separate systems.

How this was tested

Entering this table reproduces these results.

Item	Value
Pair	USD/JPY
Period	2025-01-01 to 2025-12-31 (2024 run identically for comparison)
Timeframes	15-minute / one-hour / four-hour
Bars tested	24,903 on M15, 6,226 on H1, 1,610 on H4 for 2025
Fade, long	Buy the close of a bar whose low reached the lower band; close it when a high reaches the upper band
Fade, short	Sell the close of a bar whose high reached the upper band; close it when a low reaches the lower band
Breakout	A close above the upper band goes long, a close below the lower band goes short, and the opposite break reverses at that same close
Stops and targets	None in the main grid; measured separately below
Spread	0.3 pips, zero slippage, 0.1 lots. Charged on the exit and the new entry both
Fade grid	7 periods (10, 14, 20, 25, 30, 40, 50) × 5 deviations (1, 1.5, 2, 2.5, 3σ) × 4 take-profit deviations (0.5, 1, 1.5, 2σ) = 140, run separately long and short
Breakout grid	7 periods × 5 deviations = 35
Measurement	Run through Formiq's backtester, with pips re-derived from each trade's fill prices

The long and short fades are separate systems because a band touch is a directional rule: buying the lower band and selling the upper one produce entirely different results.

Win rate and profit point in opposite directions

System	Timeframe	Profitable 2025	2025 median	Profitable 2024	2024 median	Both years	Mean win rate
Fade long	M15	19 / 140	−621 pips	51 / 140	−153 pips	5 / 140	64.0%
Fade long	H1	34 / 140	−278 pips	89 / 140	+121 pips	28 / 140	60.1%
Fade long	H4	105 / 140	+506 pips	38 / 140	−309 pips	16 / 140	69.2%

Breakout	H1	25 / 35	+789 pips	30 / 35	+838 pips	23 / 35	40.4%
Breakout	H4	12 / 35	−1,025 pips	28 / 35	+861 pips	9 / 35	36.3%

(Mean win rate is over the 2025 settings; the settings that never took a trade are left out of that column.)

The figure at the top plots the hourly row of that table, one dot per setting — win rate across, net pips up. The red and purple dots (fading) gather to the bottom right; the blue ones (following) to the top left. The settings that are right more often are the ones below zero.

Selling the upper band produced no setting at all that was profitable in both years on the 15-minute or hourly chart. USD/JPY rose 1,632 pips through 2024, and a system that keeps selling strength spent the year underneath it.

Why the higher win rate loses

The two sides of the trade are different sizes.

fade longfade shortbreakoutleft = mean loss, right = mean win, in pips, 2025

Averaged over every 2025 setting:

System	Timeframe	Mean win	Mean loss
Fade long	H1	+40.5 pips	−67.1 pips
Fade short	H1	+44.2 pips	−79.9 pips
Breakout	H1	+123.8 pips	−80.9 pips

A fade wins a little when the touch snaps back and loses a lot when price simply keeps going — the exit waits for the far band, so a trade that was wrong stays wrong for a while. The loss runs 1.7 to 1.8 times the win. A 60% hit rate does not survive winners worth 60% of the losers.

The breakout is the mirror image: wrong more often than not, but the trades that work are the ones that run.

The relationship mostly holds on the other timeframes. The fade-long wins 20.4 and loses 38.7 pips on M15, wins 83.8 and loses 139.4 on H4. The breakout wins 66.5 against 42.5 on M15, and 286.1 against 136.4 on H4.

There is one exception. On the four-hour chart the short fade wins 96.7 pips against a 88.4-pip loss — the only row where the winner is the larger side. It still came through both years in 1 setting out of 140: a favourable size ratio did not cover what 2024's rise took out of it.

The textbook 20 and 2σ, used both ways

fade (solid = 2025)breakout (solid = 2025)period 20, 2σ; the fade takes profit at 1σ

Use	Timeframe	2025	2024
Fade long, exit at 1σ	M15	703 trades, 63.58%, −669.3 pips	677 trades, 67.06%, −585.9 pips
Fade long, exit at 1σ	H1	172 trades, 62.79%, −26.6 pips	163 trades, 67.48%, −614.1 pips
Fade long, exit at 1σ	H4	40 trades, 77.50%, +1,030.3 pips	34 trades, 67.65%, −389.0 pips
Breakout	M15	570 trades, 37.72%, +292.5 pips	566 trades, 35.87%, +344.4 pips
Breakout	H1	132 trades, 43.18%, +1,177.5 pips	137 trades, 41.61%, +1,434.6 pips
Breakout	H4	41 trades, 19.51%, −2,126.7 pips	34 trades, 35.29%, +775.5 pips

The only rows profitable in both years are the 15-minute and hourly breakouts. The same two numbers, faded, lost both years on both of those charts while being right 63% to 67% of the time.

The four-hour chart changes sign between years on both sides. Its breakout took 41 trades in 2025 at a 19.51% win rate for −2,126.7 pips; that is not a sample worth drawing a conclusion from.

What the parameters did

Moving one knob at a time on the hourly chart and averaging over the rest. The last column counts settings profitable in both 2024 and 2025.

Breakout, by period

Period	2025 mean	2024 mean	Both years
10	+520 pips	+732 pips	2 / 5
14	+243 pips	+1,221 pips	3 / 5
20	+885 pips	+1,489 pips	5 / 5
25	+596 pips	+870 pips	5 / 5
30	+804 pips	+287 pips	2 / 5
40	+452 pips	+803 pips	4 / 5
50	−12 pips	+704 pips	2 / 5

Periods 20 and 25 went 5 for 5. The textbook period really is near the top — on the breakout side.

Breakout, by deviation

Deviation	2025 mean	2024 mean	Both years
1σ	+1,082 pips	+1,569 pips	7 / 7
1.5σ	+1,368 pips	+693 pips	5 / 7
2σ	+980 pips	+742 pips	6 / 7
2.5σ	−813 pips	+896 pips	2 / 7
3σ	−125 pips	+462 pips	3 / 7

A 1σ deviation went 7 for 7. Narrower bands break more often, which gives the setting a sample to stand on. Past 2.5σ a break becomes rare and the year starts deciding the result.

Fade, by deviation

Deviation	2025 mean	2024 mean	Both years
1σ	−796 pips	+6 pips	0 / 28
1.5σ	−537 pips	+28 pips	5 / 28
2σ	−266 pips	+83 pips	8 / 28
2.5σ	−85 pips	+64 pips	6 / 28
3σ	−37 pips	+156 pips	9 / 28

The fade wants the opposite: wider is less bad. Less bad, not good — every deviation averages negative in 2025, and a 1σ fade came through both years in none of its 28 settings.

Period runs the same way. On the hourly chart the fade at period 50 came through both years 8 times out of 20; at period 20, 0 times out of 20. What survives on the fade side is the setting that almost never fires.

Taking last year's winner into this year

System	2024 winner	Its 2024 result	Same setting in 2025	2025 rank	2025 median
Fade long, H1	period 40, 2σ → 1.5σ	+1,085.6 pips (70 trades)	−268.0 pips	69 / 140	−277.7 pips
Breakout, H1	period 20, 1.5σ	+2,637.8 pips (195 trades)	+1,488.1 pips	7 / 35	+788.6 pips

The fade's winner landed at the median. The breakout's winner held 7th of 35 — rare in this series, where last year's best usually does worse than picking at random.

It does not run both ways, though. The best breakout of 2025 (period 10, 1.5σ, +1,838.4 pips over 363 trades) made −156.5 pips in 2024 and ranked 33rd of 35.

Across all settings the rank correlations sit near zero.

System	2024 vs 2025	First half of 2025 vs second
Fade long, H1	+0.179	+0.079
Fade short, H1	−0.071	−0.335
Breakout, H1	+0.112	+0.142

The ADX filter turns the fade positive in 2025 and deepens its loss in 2024. Added to the breakout it came in under the unfiltered version in both years. Screening a trend-following rule for trend strength did not help it.

Exit rule	Fade 2025	Fade 2024	Breakout 2025	Breakout 2024
Opposite band only	−26.6 pips	−614.1 pips	+1,177.5 pips	+1,434.6 pips
SL 30 / TP 60	−269.5 pips	−573.5 pips	+154.5 pips	+195.6 pips
SL 50 / TP 100	−177.5 pips	−592.0 pips	+28.5 pips	+1,097.3 pips
SL 100 / TP 200	−440.2 pips	−36.3 pips	+1,320.9 pips	+1,119.0 pips
Time exit, 24 bars	+164.9 pips	−651.8 pips	+1,413.8 pips	+1,536.2 pips

Only the 24-bar time exit beat the plain version in both years, and only on the breakout (+1,177.5 → +1,413.8 and +1,434.6 → +1,536.2). Tightening the stop makes the breakout worse in a straight line: the system is built on the trades that run, and a close stop removes exactly those.

Nothing helped the fade in both years.

The fade's whole year came to what it paid in spread

Spread	Fade long 20/2σ→1σ (172 trades)	Breakout 20/2σ (132 trades)
0.0 pips	+25.0	+1,217.1
0.3 pips	−26.6	+1,177.5
0.6 pips	−78.2	+1,137.9
1.0 pips	−147.0	+1,085.1
1.5 pips	−233.0	+1,019.1
2.0 pips	−319.0	+953.1

At a zero spread the fade makes 25.0 pips; at 0.3 pips it loses 26.6. A year of work came to about what it handed over in costs — the 51.6-pip difference is exactly 172 trades × 0.3 pips.

The breakout still keeps 953.1 pips at a 2.0-pip spread. It loses 264.0 pips going from 0 to 2.0, which is 132 × 2.0. The same relationship held without error in QQE and moving average crossovers.

What this test supports

Only what pointed the same way in both years.

1. One indicator, two systems, opposite conclusions. On the hourly chart, settings profitable in both years: 28 of 140 fading the lower band, 0 of 140 fading the upper, 23 of 35 following the break
2. Sorting by win rate picks the wrong side. The fade averaged 60.1% and the breakout 40.4%; the size of each side cancels that out
3. For the breakout, narrower. A 1σ deviation was profitable in both years in all 7 of its settings. For the fade, wider — a 1σ fade in none of its 28
4. The textbook 20 and 2σ is a reasonable breakout setting. It made money in both years on the 15-minute and hourly charts, and lost money in both years faded on the same two
5. The more it trades, the more the spread decides it. A year of the fade was worth roughly what it paid to trade

Choosing the fade because it wins more often is not something this test supports. Win rate and profit run in opposite directions for other indicators too, but Bollinger Bands let both sides be measured on one indicator, which sharpens the gap. RSI measured the same two ways opened the gap wider still: 65.3% for the fade against 23.7% for the cross. Building the rules without writing code is how to repeat any of this on your own pair.

Limits of this test

• One pair, USD/JPY, and two years. Nothing here guarantees the same pattern elsewhere
• The two years are very different. 2024 rose 1,632 pips through a 2,237-pip range; 2025 finished 56 pips lower through a 1,900-pip range. That rise is most of why selling the upper band was wiped out in 2024
• The fade holds until the far band with no stop, so a trade that goes wrong shows its full loss. Stops are measured in their own section
• The breakout reads closes. A bar whose wick pierced a band but whose close came back inside is not a signal
• Entries and exits fill at bar closes. Real fills differ
• The spread is a flat 0.3 pips throughout. Real spreads move with the session and around releases
• Four-hour settings trade between 4 and 202 times a year on the fade side, and one breakout setting took no trades at all. Win rates and profit factors at those counts are wide numbers before anything else is said
• Price moves by different amounts at different hours, which the session-filter rows are exposed to
