The short answer
An inside bar has a lower high and a higher low than the bar before it (the mother bar). The breakout trade buys a move above the inside bar or sells a move below it. We tested it on gold:
- Daily, since 2015: 321 trades, 42.7% winners, +$1,061 per ounce after costs, profit factor 1.29, positive in both 2015–2020 and 2021–2026.
- Daily with a 50 EMA trend filter: 219 trades, 45.2% winners, +$1,290 per ounce, profit factor 1.56.
- 4-hour, two years: flat without a filter (−$30); +$236 with the filter.
- Hourly, two years: 1,178 trades, −$1,987 per ounce. It lost clearly, with or without the filter.
Most of the daily profit came from long trades in gold’s long bull market, so a trend filter that kept the rule on the right side did most of the work.
What an inside bar tells you
An inside bar is a pause: buyers and sellers both failed to extend the previous bar’s range. On gold, inside days often appear before a scheduled event (a Fed decision, payrolls) or after a large move, as the market digests it. The breakout trade assumes the pause ends with a move in one direction, and that the move is big enough to pay for the false starts.
Inside days are common. 433 of 2,974 trading days since 2015 were inside days, about 15%, or roughly one a week. For the visual side of the pattern and related candles, see our candlestick patterns lesson.
Exact rules
| Rule | Main version |
|---|---|
| Set-up | Bar closes with high below the previous high and low above the previous low |
| Orders | Buy stop at the inside bar’s high and sell stop at its low; the first fill cancels the other |
| Order life | The next bar only (daily: the next day) |
| Stop | The opposite side of the inside bar |
| Target | 2R |
| Time exit | 5 bars on daily, 6 bars on H4, 12 bars on H1 |
| Size | 1 ounce, one trade at a time |
Variants:
- 50 EMA filter: only the buy stop if the inside bar closed above the 50 EMA, only the sell stop if below.
- Mother-bar break (daily): entries at the mother bar’s high and low, stop at the mother bar’s midpoint, 2R target.
How we tested it
Data. COMEX gold futures (GC=F) daily bars from January 2015 to October 2026, and 1-hour bars from 30 October 2024 to 30 October 2026, with 4-hour candles built from them in New York time (18:00, 22:00, 02:00, 06:00, 10:00, 14:00). Execution. Stop orders fill at the level, or at the open if price gaps through it. Inside the fill bar we assume the usual path (up bar: open, low, high, close; down bar: open, high, low, close) and count only stops or targets reached after the fill; if both are possible, the stop counts. When both sides break on the same bar, the first side on that path fills and its stop (the other side) is then hit, so the trade counts as a loss. Cost. $0.30 per ounce per round trip.

What the results say, in plain English
- Daily inside bars worked; hourly ones did not. A daily inside bar compresses a full day of trading, and its break often starts a multi-day move. An hourly inside bar is often just a quiet hour, and its break is noise.
- The trend filter mattered, but read it carefully. On daily data it lifted the profit factor from 1.29 to 1.56, yet nearly all of its gain came after 2021 (2015–2020 made only $23). The filter mostly kept the rule long in a bull market.
- Same-day double breaks are the main risk. 60 of the 321 daily trades came on days that broke both sides, each a full loss.
- Costs barely matter on daily; they matter a lot on H1. The hourly version paid $353 in costs and lost $1,634 before them anyway.
- The 4-hour chart is a grey zone. Without the filter it was flat; with it, slightly positive in both years. Not enough to rely on.
When the inside bar breakout fails
- Event days. An inside day before a Fed decision or payrolls often breaks one side on the release, then the other.
- Range-bound markets. In 2015, 2018 and 2019, when gold was quiet, the daily version lost or broke even.
- Tiny inside bars. A very small inside bar means a tight stop, easily hit by normal noise and by the spread.
- Counter-trend breaks. Without the filter, shorts lost money on daily data across eleven years of mostly rising prices.
How to trade it more carefully
- Prefer daily inside bars and use the hourly chart only to manage the entry.
- Check the calendar. If the next day has CPI, payrolls or a Fed decision, either skip it or accept a double-break risk. Our economic calendar lists the dates.
- Trade with the trend. A 50 EMA or simple market-structure read keeps you on the stronger side.
- Consider a retest. Some traders wait for the break, then a pullback to the inside bar’s edge, as in our breakout and retest lesson.
Risk sizing
The daily stop (the inside bar’s full range) averaged about $21.50 per ounce over the test period, larger in recent years. Risking $100:
- $100 / ($21.50 + $0.30) is about 4.6 ounces (0.05 lots).
- The worst losing streak on daily data was 8 trades, about $800 at that size.
Recalculate size for every set-up with the position size calculator, because the inside bar’s range sets the stop.
Checklist before you trade an inside bar
- Confirm it is a true inside bar: a lower high and a higher low than the mother bar, on the timeframe you actually trade.
- Check the size. A very small inside bar gives a stop that the spread and normal noise can hit; a very large one may be too wide to size sensibly.
- Note the trend. In our daily test, the 50 EMA filter lifted the profit factor from 1.29 to 1.56.
- Look at the next day’s calendar. Inside days before major releases are prone to breaking both sides.
- Decide how long the order lives. We used one bar; leaving orders open longer changes the results.
- Plan the exit. Our daily version exited after five days if neither the stop nor the 2R target was hit; write your own time exit down before entering.

Frequently asked questions
Does the inside bar breakout work on gold?
On the daily chart it did in our test: since 2015, trading the break of a daily inside bar with the stop at the other side and a 2R target made 321 trades and $1,061 per ounce after costs, profit factor 1.29. Adding a 50 EMA direction filter improved it to $1,290 over 219 trades. On the hourly chart it lost $1,987 per ounce over 1,178 trades.
How often does gold form an inside day?
On 433 of 2,974 trading days from 2015 to October 2026, about 15% of days, or roughly one day in seven.
Where should the stop go on an inside bar breakout?
The classic stop is the opposite side of the inside bar, which is what our main test used. A wider stop at the mother bar’s midpoint, with entries at the mother bar’s high or low, also made money on daily data but less.
Should I trade both sides of an inside bar?
Our main test placed a buy stop above and a sell stop below, and took whichever filled first. Using a 50 EMA filter to trade only in the trend’s direction improved the daily result and was the only H4 version that made money.
What is the best timeframe for inside bar trading on gold?
In our tests, daily. The daily version was positive in both 2015–2020 and 2021–2026. The 4-hour version was flat without a filter and slightly positive with one. The hourly version lost in both years.
What happens when both sides of an inside bar break on the same day?
That is the most common way the set-up loses. In our daily test, 60 of 321 trades came on days that traded through both sides; we counted them as losses because the opposite side is the stop.
