OpenDrive Momentum EA

Trade the US regular-session opening drive with a systematic, rules-based approach.

OpenDrive Momentum EA is an MQL5 Expert Advisor for MetaTrader 5 that captures the directional persistence of the first US regular-trading-hours (RTH) bar on H1 charts. The strategy is rooted in a well-documented market microstructure phenomenon: institutional execution algorithms (VWAP/TWAP) distribute large orders across the trading day, creating measurable order-flow imbalance that often persists beyond the opening auction. The EA enters at the open of the second session bar when the first bar's return exceeds a configurable threshold, holds for a fixed number of bars, and flattens overnight — no gap risk, no weekend exposure.

How It Works

The EA operates exclusively during US regular trading hours (default 9:30–16:00 ET, configurable). On each trading day, it evaluates the first RTH bar's percent return:

• Return ≥ threshold → Long at the open of the second session bar
• Return ≤ -threshold → Short at the open of the second session bar
• Return within threshold → No trade that day

The position is held for InpHoldBars bars (default 6, configurable 3–6) and is always closed before the next day's session open. An emergency stop-loss (default 5%, configurable) provides a safety backstop.

Key Features

• Pure systematic logic — no indicators, no curve-fitted oscillators, no machine learning. Every trade follows a transparent, reproducible rule.
• Flat overnight — positions are closed by session end or at the next day's open. No gap risk, no weekend exposure.
• Configurable parameters — threshold (0.2–0.8%), hold bars (3–6), session hours, lot size, emergency stop-loss.
• Single-chart setup — attach to any US index or ETF H1 chart (QQQ, SPY, US500, NAS100). One chart, one EA.
• Lightweight execution — no external dependencies, no DLL imports. Pure MQL5 with standard Trade library.

Note on sample size: 18 trades is a small sample. The strategy is highly selective by design (it only trades when the first RTH bar's return exceeds the threshold). The Python research below covers a longer horizon and more trades on QQQ.

Python research (QQQ H1, walk-forward analysis): 6 of 7 walk-forward folds positive. Average trade +0.33 USD. OOS plateau consistently positive across threshold/hold parameter combinations.
