Stochastic Daily Breakout for Gold, +245 Percent in a 2021-2026 Backtest - MetaTrader 5용 expert

Stochastic Daily Breakout combines two simple ideas on gold. A turn in the stochastic signal line marks a possible change in momentum, and yesterday's high and low mark the levels where that change has to be confirmed. The EA never buys or sells at the market: it places a stop order at one of those levels, so the trade opens only if price actually gets there.

The code is short and self-contained. The stochastic is computed inside the EA, because this variant uses the close-to-close range with SMMA smoothing, which differs from the built-in iStochastic. The only built-in indicator is iBands. The EA trades one position at a time.

Trading rules

• Buy: the stochastic signal line turns down (a peak on the previous bar) and the open three bars ago is below the upper Bollinger band. A buy stop goes to yesterday's high.
• Sell: the signal line turns up (a trough on the previous bar) and the open three bars ago is above the lower Bollinger band. A sell stop goes to yesterday's low.
• Stop loss and take profit: 1.9% of the entry price each.
• Expiry: an unfilled order is cancelled after 9 bars; a new signal on the same side replaces it.
• Indicators: stochastic 23/3/7, Bollinger bands 9 periods, 2.0 deviations, weighted price.

How the strategy was built and validated

This strategy was not tuned by hand on a chart. It came out of an automated search on five years of XAUUSD history, where six independent genetic builders, each with its own out-of-sample period, generated and tested candidate strategies.

Every candidate needed a healthy trade structure, with results that do not depend on a single trade or a single day. Then it had to pass a chain of robustness tests, including other timeframes, related markets, Monte Carlo simulations with spread stress, parameter stability, walk-forward analysis and more, where a single failure is enough to discard it.

This EA was found among more than two million candidate strategies tested for its family.

Backtest

The test was run on XAUUSD H1 in the "Every tick based on real ticks" mode, from July 2021 to September 2026, with a 1,000 USD deposit, 1:100 leverage and a fixed 0.01 lot. Real ticks cover about a quarter of that period; for the rest, the tester generated ticks from M1 data. The net profit was 2,453 USD (+245%), with a profit factor of 1.54, a recovery factor of 5.56 and a maximum equity drawdown of 23.9%. There were 213 trades: 116 buys, 66.4% of them winners, and 97 sells, 50.5% winners. The results scale with the lot: at a fixed 0.01 lot, a larger deposit shows a smaller percentage.

Inputs

• InpLots — volume per trade (default 0.01).
• InpMagic — magic number of the EA's orders.
• InpBandPeriod — Bollinger band period.
• InpKPeriod, InpDPeriod, InpSlowing — stochastic periods.
• InpStopPct, InpTargetPct — stop and target, in percent of the entry price.
• InpExpiryBars — bars a pending order stays alive.

Attach the EA to an XAUUSD H1 chart. The defaults are the tested values. A backtest is not a promise of future results, so test it on a demo account with your broker's prices before trading real money.
