Meridian EA MT5

Meridian EA MT5

Meridian EA is a machine learning trading system powered by two XGBoost gradient-boosted tree models trained on years of real tick data. One model identifies long setups, the other identifies shorts. Both run natively inside MetaTrader 5 as compiled MQL5 code. No internet required, no DLLs, no Python, no external API calls.

This is not an indicator with "AI" in the name. This is the same class of algorithm used by quantitative hedge funds and Kaggle competition winners, transpiled into MQL5 and executing locally on your terminal.

HOW IT WORKS

Every new H1 bar, the EA computes 40 normalized market features: price action structure, volatility regime, momentum dynamics, session timing, candle morphology, and trend context across multiple timeframes.

Both models score the current bar independently. A trade is only placed when:

• One model outputs high confidence for a direction
• The other model confirms low probability for the opposite direction
• The confidence gap exceeds a configurable threshold

When the market is unclear, both models produce similar scores and the EA stays flat. It only trades when there is a measurable statistical edge. This dual-model architecture is why the system avoids the choppy losses that destroy most EAs.

WHAT MAKES THIS DIFFERENT

Most products on this marketplace that claim to use AI are either calling an external API (adding latency and breaking in the tester), using a single indicator with "AI" in the product name, or running a basic neural network with no proper validation.

Meridian's models were:
- Trained on real broker tick data, not synthetic or generated data
- Validated using walk-forward analysis, not just in-sample optimization
- Tested for overfitting using label randomization (model beats random labels by 29.5%)
- Transpiled into native MQL5 for zero-dependency execution

The model files ship as part of the EA. When you backtest, you see exactly what the model would have done in real time. No hindsight bias, no look-ahead.

SUPPORTED PAIRS

• USDJPY - Strongest performance, lowest drawdown at 6.8%
• GBPUSD - High trade frequency, strong trend capture
• EURUSD - Most liquid pair, largest sample size with 1,496 trades

Pre-built .set files included for each pair. Attach to H1 chart, load the preset, done.

RISK MANAGEMENT

Every trade opens with a hard stop loss and take profit. No exceptions.

• Fixed percentage risk per trade (default 1%, configurable from 0.5% to 3%)
• ATR-based stop loss and take profit that adapts to current volatility
• Maximum trades per day limit
• Maximum simultaneous open positions limit
• Daily loss circuit breaker (pauses all trading after 3% daily drawdown)
• Optional trailing stop that locks in profits as the trade moves in your favor
• Spread filter to avoid entries during poor execution conditions

PROP FIRM MODE

Built-in safety mode for funded account challenges (FTMO, The5ers, FundedNext, and others):

- Configurable daily drawdown limit
- Configurable total drawdown limit
- Automatically stops trading before hitting prop firm limits
- Enable with one click in settings
- Use the Conservative preset (0.5% risk, 3-5% expected drawdown) for maximum safety

WHAT THIS EA DOES NOT DO

- No martingale (no doubling after losses)
- No grid trading (no averaging into losing positions)
- No hidden stop losses
- No lot multiplication after losses
- No recovery mode
- No tick scalping that only works on demo spreads

Every position has a defined risk from entry. You always know your maximum loss before the trade opens.
