We use this EA as a trading tool.
There are 3 inputs required, as follows:
- Profit Target
- Cut Loss
- Magic Number
extern double inTargetProfitMoney = 10; //Target Profit ($) extern double inCutLossMoney = 0.0; //Cut Loss ($) extern int inMagicNumber = 0; //Magic Number
When this EA is executed, it will first call the OnInit () function. Where we will verify the input and variable initialization
int OnInit() { //--- if(inTargetProfitMoney <= 0) { Alert("Invalid input"); return(INIT_PARAMETERS_INCORRECT); } inCutLossMoney = MathAbs(inCutLossMoney) * -1; //--- return(INIT_SUCCEEDED); }
And every time the price movement (tick) will call the OnTick () function
void OnTick() { //--- double tFloating = 0.0; int tOrder = OrdersTotal(); for(int i=tOrder-1; i>=0; i--) { if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) { if(OrderMagicNumber() == inMagicNumber) { tFloating += OrderProfit()+OrderCommission() + OrderSwap(); } } } if(tFloating >= inTargetProfitMoney || (tFloating <= inCutLossMoney && inCutLossMoney < 0)) { fCloseAllOrders(); } }
In the OnTick function, it will continue to calculate the total profit or loss. Then will close all orders that can be fulfilled the target or maximum loss limit
void fCloseAllOrders() { double priceClose = 0.0; int tOrders = OrdersTotal(); for(int i=tOrders-1; i>=0; i--) { if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) { if(OrderMagicNumber() == inMagicNumber && (OrderType() == OP_BUY || OrderType() == OP_SELL)) { priceClose = (OrderType()==OP_BUY)?MarketInfo(OrderSymbol(), MODE_BID):MarketInfo(OrderSymbol(), MODE_ASK); if(!OrderClose(OrderTicket(), OrderLots(), priceClose, slippage, clrGold)) { Print("WARNING: Close Failed"); } } } } }
