This Is a Different Thing from the Old MEGAMAX v3.6
The old MEGAMAX EA v3.6 (Asia Range Breakout, 11 pairs) blew up on all pairs in live MT5 verification (redesign required) and was taken down(See the old version's verification results here)。
This EA inherits the name but is a complete redesign. The strategy is changed to a simple USDJPY H1 Donchian channel breakout (BUY-only), and after 17 PDCA optimization cycles in Python, we re-verified 9.4 years (2017-2026) in the live MT5 Strategy Tester and passed — we publish only what passed.
New EA · Donchian breakout + ATR exit + time-based exit
MEGAMAX DONCHIAN USDJPY EA
USDJPY H1 with-trend breakout (+9.4%/yr / 9.4-yr live)
It enters with the trend on an upside break of an N-bar Donchian channel, extends profits with an ATR-based initial SL + trailing stop, and exits on time after a set number of bars — a BUY-only breakout EA.Since the buy direction is the swap-receiving side, it is also advantageous on holding costs over the long term. It uses no averaging-down or martingale whatsoever.In 9.4 years (2017-2026) of live MT5 BT, +133.1% / PF=1.44 / max DD 6.2%.

Design Highlights (eliminating over-optimization)
- Parameters use the median of the plateau — avoiding single-peak over-optimization
- Robustness confirmed via 3x-spread stress and walk-forward (IS 2012-2019 / OOS 2020-2025)
- BUY-only = swap-receiving side. Swap costs don't work against it even when holding long term
- No averaging-down or martingale. Per-trade risk is fixed with an ATR-based SL

MEGAMAX DONCHIAN JPY Family (all 9.4-yr live MT5 verified)
The same strategy deployed to several JPY crosses. With low correlation, it suits diversified operation. All are live MT5 Strategy Tester measurements (every-tick equivalent / real spread) for 2017-2026.
| Pair / TF | PF | Max DD | Win Rate | Trades | 15 yr |
|---|---|---|---|---|---|
| USDJPY / H1 ★ main N40 Trailing | 1.44 | 6.2% | 32.8% | 619 | +133.4% |
| EURJPY / H1 N20 (2017-2026) | 1.49 | 6.0% | 25.0% | 312 | +74.7% |
| GBPJPY / H4 N40 Trailing | 1.41 | 4.7% | 38.5% | 148 | +18.2% |
* The 4 JPY crosses are distributed as a single "MEGAMAX DONCHIAN JPY Pack" (EA + per-pair H4 presets included). The detailed presets for each pair are described in the README inside the zip. The annual return is modest, but it is a solid, low-DD type consistent over 9.4 years.
★NEW — one EA, three pairs at once
MEGAMAX DONCHIAN JPY (multi-pair)
Instead of running USDJPY, GBPJPY and EURJPY on three separate charts, drop ONE EA on ONE chart and it trades all three at once. Each pair runs its own validated config (per-symbol channel / timeframe / trail / hold), and its backtest is byte-identical to the standalone version (USDJPY within 0.4%, GBPJPY/EURJPY exact).
- • Buy-only Donchian breakout + hard SL + ATR trail + time-exit (same engine as the standalone)
- • Missing symbols auto-skipped, broker suffix auto-detected (works on any MT5)
- • One install, one chart, 3-pair diversification (no more 3-chart setup)
Free with account registration (account-locked). Download the multi-pair and per-pair versions from your dashboard after registering.
How the strategy works (entry, stop, target)
On USDJPY H1, it follows Donchian-channel breakouts with an ATR trailing stop — a robust trend follower with consistent results across 15 years of real-tick testing.

Run Mode (Defensive / Standard / Aggressive)
Every EA exposes a "RunMode" dropdown that switches aggressiveness across three levels. It only multiplies the lot (risk) — entry/exit logic, symbol and timeframe never change.
Defensive
×0.5Half of standard risk. Both max drawdown and expected return are roughly halved. For capital preservation or first-time automated trading.
Standard (recommended)
×1.0The backtest figures shown on this page use this setting. Start here.
Aggressive
×2.0Double the standard risk. Return and max drawdown roughly double, raising the risk of ruin. Use only with money you can afford to lose.
Approximations relative to Standard (Defensive ≈ 0.5x / Aggressive ≈ 2x). Drawdown does not scale linearly; in sharp markets Aggressive can exceed this estimate. Lots auto-adjust to balance when compounding is on.
