RegressionExpert EA MT4 – Regression-Based Trend Trading for EURUSD, USDJPY & GBPUSD

RegressionExpert EA applies dynamic regression modelling to identify high-probability trend entries on M5 charts across three major pairs on MetaTrader 4. Backtests at 99.80–99.90% modelling quality across multiple instruments validate the approach over multi-year datasets. Results originate from 99%+ tick-quality simulations — not curve-fitted optimisations.

Backtest Performance Results

EURUSD – Primary Backtest (2021–2023)

The EURUSD backtest demonstrates a profit factor of 2.04 over 690 trades from March 2021 to March 2023. Starting from a $1,000 deposit, net profit reached $4,387.56 — a 438% return over two years. Modelling quality reached 99.80% using every-tick simulation, the most precise available method.

Relative drawdown recorded at 9.65% — the lowest across all three instruments tested. Win rate reached 90.86% across 365 winning trades out of 297 settled short and long positions combined.

USDJPY – Extended Historical Backtest (2003–2021)

The USDJPY simulation extends across 18 years of price data from June 2003 to March 2021, covering multiple market cycles. It demonstrates a profit factor of 2.28 on 819 total trades with a 99.90% modelling quality score. Net profit reached $8,942.12 from a $1,000 starting balance.

Relative drawdown on USDJPY reached 15.43% — moderate given the dataset spans two decades. Long position win rate recorded at 90.30%.

GBPUSD – Short-Window Backtest (2023)

The GBPUSD simulation covers June to August 2023 — a three-month window only. It shows a profit factor of 1.83 across 1,563 trades with a 99.90% modelling quality score. Relative drawdown reached 21.95% — the highest of the three instruments.

The GBPUSD dataset is short. Three months cannot validate behaviour across ranging, trending, or high-volatility news regimes. The anomalously high “Total Net Profit” figure of $156,879 in the raw data conflicts with gross profit and loss figures — treat GBPUSD results as indicative only pending extended testing.

The 21.95% relative drawdown on GBPUSD stems from short-leg losses reaching -$5,691 on a single trade — short positions won only 15.64% of the time in this window. Manage this by keeping GBPUSD allocation to no more than one-third of total capital, setting the maximum lot size conservatively via the EA’s lot input, and monitoring short-side exposure actively during high-impact GBP news events. Under these controls, realistic outcomes range from managed drawdown recovery to reduced win rate — not account destruction. The USDJPY and EURUSD signals provide structural balance.

Backtest results differ from live trading due to slippage, spread variation, and execution latency. USDJPY data is 4+ years old — run a 90-day demo on USDJPY to validate under current market conditions before live deployment. GBPUSD dataset is three months — treat as preliminary only. Demo validation mandatory 60+ days minimum before live capital.

How It Works

Strategy: Dynamic regression channel modelling on M5 — identifies directional price deviations and trades mean-reversion or breakout continuations across EURUSD, USDJPY, GBPUSD.

Entry: Triggers when price breaches regression channel boundary with directional confirmation — long bias favoured across all three pairs tested.

Exit: Closes at regression midline or defined profit target — losing trades exit at stop-loss threshold to cap drawdown.

Risk Control: Fixed lot sizing — no martingale, no position doubling. Maximum consecutive losses recorded at 2–4 trades across all backtests.

✅ Best conditions: Trending intraday sessions • Low spread ECN execution • Stable liquidity periods (London/New York overlap)

⚠️ Caution: High-impact news events (non-farm payrolls, central bank decisions) • Ranging, choppy M5 price action with no directional follow-through
