The Classes
CAtsSizer - Lot size calculation based on stop distance
Supported Modes: Fixed lot size, Percentage of balance, Percentage of equity, Fixed monetary amount.
This class ensures the lot size is floored to the volume step. It strictly avoids rounding up. If the calculated risk results in a lot size smaller than the broker's minimum lot, the Lots() function returns 0.0, and LastReason() will explain why. Rounding up to the minimum lot is a common practice that can lead to an EA risking more than the intended percentage on smaller accounts.
Includes optional lot capping and a free margin check (OrderCalcMargin).
CAtsDayGuard - Daily trading limits
Features: Daily loss limit as a percentage of the day-start balance and/or a fixed monetary amount (whichever is more restrictive is applied), an optional daily profit target, and a maximum number of trades per day.
Configuration: You can specify the server hour at which a new trading day begins and whether open profit/loss should be included in the daily calculation.
Persistence: Day-start balance and lock levels are saved using GlobalVariables, ensuring that restarting the terminal mid-day does not reset these limits.
Status Indicators: Remaining(), Used(), and Level() (indicating OK, WARNING, or LIMIT REACHED) are available for displaying on a panel.
CAtsDrawdownGuard - Maximum overall loss management
Modes: Static (loss calculated from the initial balance), Trailing on equity, or Trailing on balance.
