Orca

Orca detects trends and slight price stagnation, aiming to take positions in the direction of the breakout.

By avoiding tricky price movements during range conditions and targeting breakouts, it achieves tight stop losses.

It performs well in trending markets but tends to stagnate during prolonged range conditions.

It is suitable for instruments like USDJPY and Gold, where trends often result in one-sided price movements.

This EA operates on the H1 timeframe.■Parameter Descriptions

■LotManagement --- When set to true, enables compound lot sizing.

■LotFactor --- When LotManagement is true, this value is used to calculate the lot size.

■FixedLot --- When LotManagement is false, this value is used as the fixed lot size.

■MaxLot --- Maximum lot size for trading. The EA will not trade above this value.

■MiniLot --- Minimum lot size for trading. The EA will not trade below this value.

■RecoveryMode --- If true, enables recovery mode. In recovery mode, the EA remembers the original account balance. If the balance decreases due to losses, the EA increases lot size with each trade until the original balance is recovered. The lot size during recovery mode is calculated as (base lot × RecoveryCount × RecoveryLotMultiplier). RecoveryCount increases by 1 with each trade until the original balance is restored.

The target account balance is displayed on the chart as RecoveryGoalBalance. This value is not reset even if MT5 is restarted. However, changing the MagicNumber or pressing the "Reset RecoveryMode" button on the chart will reset both RecoveryCount and RecoveryGoalBalance.

■MaxRecoveryCount --- Maximum limit for RecoveryCount.

■RecoveryLotMultiplier --- Each time RecoveryCount increases by 1, the lot size is multiplied by this value.

■MagicNumber --- EA identifier. The EA uses the combination of the symbol and MagicNumber to identify its own positions. If you run multiple instances of this EA on the same symbol, use different MagicNumbers.
