# RM

Risk management library: position sizing, SL/TP calculation, OCO orders and account-level loss/profit limits.

## Main features
- Lot size and SL/TP calculation based on account risk (`CRiskManagemet`).
- Personal and prop-firm risk profiles (`CRiskManagemetPersonal`, `CRiskManagemetPropFirm`).
- Max loss / max profit limits (daily, weekly, monthly, since peak) with automatic position closing — see [LossProfit](./LossProfit/README.md) for the full inheritance model.
- OCO (one-cancels-other) order linking.
- Per-account order/position tracking (`COrderGestor`, `CTicketsTable`).

## Basic usage

### Risk management
```mql5
CRiskManagemet rm;
// Note: "rm" requires the lot, type, max profit and max loss to be reset (etc.)
// before calling functions like GetSL, GetLote, etc.

// Check if a limit was hit
if(g_loss_profit_manager.MaxLossIsSuperated())
  {
   risk.CloseAllPositions();
   CanTrade = false;
  }

// Lot size
double entry_price = 1000.0;
double l = risk.GetLote(ORDER_TYPE_BUY, entry_price, 100, 0);

// Stop loss
long sl = risk.GetSL(ORDER_TYPE_BUY, entry_price, 100, 0);

// And more: GetPositionsTotal, SetStopLoss, CloseAllOrders, GetPositions...
```

### OCO order
```mql5
COcoOrder oco;

void Function()
{
 unsigned long ticket1 = trade.ResultOrder();
 unsigned long ticket2 = trade.ResultOrder();

 oco.AddOrders(ticket1, ticket2);
}
```
