🤖 AI Trading Bots
Strategies ported from MetaTrader 5 cluster-latest EA:

2. Darvas Box
Source: DarvasBoxStrategy.mqh
Logic: Detects consolidation boxes and trades volume-confirmed breakouts.
3. EMA Slope
Source: EMASlopeDistanceStrategy.mqh
Logic: Arms when price stretches from sloping EMA, trades the trend, exits on cross-back.
