Dark Algo EA — EURUSD Grid Strategy with 20-Year Backtest at 99.90% Modeling Quality

Dark Algo EA is a EURUSD-focused expert advisor for MetaTrader 4 that combines Stochastic oscillator signals with ATR-based volatility filtering to time grid entries on the H1 timeframe.

A 20-year backtest at 99.90% modeling quality on $1,000 capital shows a 2.85 profit factor, 75.54% win rate, and 15.76% relative drawdown across 4,370 trades.

Key Benefits

• ✅ 20-Year Backtest Depth: 99.90% modeling quality on H1 EURUSD from 2003–2023 — a test window that includes the 2008 crisis, 2015 SNB shock, and COVID volatility; the cost is that live slippage and spread spikes are not reflected. Compare EA strategies
• ✅ Grid Strategy with ATR Timing: Entries are spaced by a 250-pip distance filter and timed using ATR volatility confirmation — captures trending and ranging periods but compounds exposure when multiple positions stack in one direction.
• ✅ Monetary Stop Loss Circuit Breaker: A fixed monetary stop loss (1,100 account currency units, scaled by lot size) closes the entire basket before a single session wipes the account — Partial control: it limits the worst case, but does not prevent incremental drawdown from building.
• ✅ Bidirectional Trading on All Sessions: Buys and sells simultaneously across all five trading days, including Saturday — broad session coverage but no time filter is active by default, so the EA trades through low-liquidity windows unless configured otherwise.

Dark Algo EA Performance

No live Myfxbook signal is linked for this EA — all documented performance figures come from backtests.

The primary backtest runs 20 years on EURUSD H1 (May 2003 – January 2023), starting from $1,000, producing a 2.85 profit factor, 75.54% win rate, and 15.76% relative drawdown across 4,370 completed trades at 99.90% modeling quality.

A second backtest on the same symbol and period using IC Markets SC-Live16 broker data (build 1369) confirms a 2.80 profit factor and 14.80% relative drawdown, with a final balance of $27,461 — consistent with the primary test result.

The grid mechanism stacks positions when price moves against the initial entry — each new order opens 250 pips from the previous at H1 bar boundaries. During a sustained unidirectional EURUSD move (as seen in the April 2025 USD selloff documented in user reviews, where EUR/USD moved 300+ pips in a single day), the basket can reach 5+ open positions in one direction simultaneously. That is correlated exposure, not diversification.

This is a Partial weakness: the 250-pip spacing and Max Spread filter (89 pips) reduce runaway accumulation, but they do not prevent the basket from building in a fast trend. The monetary stop loss — set at 1,100 account currency units scaled by lot size — is the primary hard floor.

At the default Risk Factor 6.0 with $1,000 capital, the 20-year backtest held peak relative drawdown to 15.76%. One verified live user running Risk Level 12 on a 5K EUR account reported 7.38% drawdown during the April 2025 Trump tariff volatility event — a data point consistent with the backtest range at that capital level, though a single session cannot confirm long-run behavior.

A 20-year backtest at 99.90% modeling quality confirms historical pattern robustness — it does not account for live spread widening, slippage, or broker-specific execution that will affect your real results.

How Dark Algo EA Works

Mechanism: Dark Algo trades EURUSD on the H1 timeframe using a grid system triggered by Stochastic momentum exhaustion and ATR volatility confirmation. When the Stochastic (5/3/19, SMA, Close/Close) signals a potential reversal and ATR confirms sufficient volatility, the EA opens an initial position. If price continues against the trade, it layers additional positions every 250 pips — one new order per H1 bar maximum — compounding position size as the trade develops. This design is built to recover from initial adverse moves by averaging into a favorable average entry price, then closing the basket at a unified take profit or at the open price of the original trade.

Signal Trigger: Stochastic slow K (5 periods), slow D (3 periods), slowing (19), SMA mode on Close/Close prices — H1 timeframe. ATR (10-period main, 5-period secondary) must confirm volatility before entry fires. Both buy and sell signals are active simultaneously.

Position Close: Basket closes at Take Target (50 pips profit) or when price returns to the open price of the first trade in the basket (Close on Open Price = true). The monetary stop loss at 1,100 units (scaled by starting lot size) forces a full basket close if floating loss reaches that threshold.

Exposure Limits: Max grid orders capped at 100; one new grid order per H1 bar; Max Spread 89 pips and Max Average Spread 89 pips prevent entries during spread spikes; monetary stop loss at 1,100 account currency units (multiplied by lot size ratio) acts as the account-level circuit breaker.

✅ Optimal conditions: Ranging or moderately trending EURUSD during normal spread conditions; sessions where H1 bars close with defined directional momentum followed by mean reversion. The 20-year backtest — which includes multiple high-volatility regimes — shows the strategy recovering across diverse market phases.

⚠️ Avoid when: EURUSD is in a fast, sustained unidirectional trend (300+ pip moves in one session) without mean reversion — grid stacking accelerates without a close trigger. Also avoid during broker spread widening events above 89 pips, which the Max Spread filter blocks entries for but does not close existing open positions.

Recommended Settings

Who Should Use Dark Algo EA

• ✅ Running MT4 on a VPS with stable 24/5 connectivity — H1 bar timing requires the EA to be online at every hourly candle close
• ✅ Trading EURUSD exclusively with a minimum $1,000 account — the backtest used exactly this capital; undercapitalized accounts reduce the monetary stop loss buffer proportionally
• ✅ Comfortable holding multiple open positions in a grid — this EA will have 2–5 simultaneous trades during adverse moves; traders who cannot tolerate floating drawdown above 10% should lower the Risk Factor before going live
• ✅ Willing to demo-test 60–90 days before committing live capital — no live Myfxbook signal exists; backtest results require live validation on your specific broker’s spread and execution environment

Performance verified with: MT4 build 1369, IC Markets SC-Live16 broker data, EURUSD H1, $1,000 starting capital.
