📊 Money Management Modes

1. Fixed Lot (MM_FIXED = 0)

Trades with a constant lot size defined by FixedLot.

2. Risk Percentage (MM_RISK_PERCENT = 1) — Recommended

Each trade risks up to RiskPercent percent of account equity.
Lot size is calculated based on the stop loss distance.

Formula:
Lot Size = (Account Balance × Risk %) / (Stop Loss Distance × Pip Value)

3. Kelly Criterion (MM_KELY = 2)

Calculates the optimal position size based on historical performance, including win rate and reward/loss ratio.
Best suited for accounts with enough trading history.

4. Anti-Martingale (MM_ANTI_MARTINGALE = 3)

• Increase lot size after a winning trade
• Decrease lot size after a losing trade

🛡️ Risk Management Features

Daily Loss Limit

If daily loss reaches MaxDailyLoss, the bot will stop opening new trades until the next day.

Consecutive Loss Protection

After MaxConsecutiveLosses losing trades in a row, the bot stops trading automatically.

Trailing Stop

Once the trade reaches TrailingStart pips in profit, the stop loss moves forward automatically by TrailingStep pips to protect gains.
