Next, we will declare our arrays, calculate our stop loss and take profit, and load our calculated prices
into the array:
double BuyTakeProfit[3];
double BuyStopLoss[3];
BuyTakeProfit[0] = CalcBuyTakeProfit(Symbol(),TakeProfit1,Ask);
BuyTakeProfit[1] = CalcBuyTakeProfit(Symbol(),TakeProfit2,Ask);
BuyTakeProfit[2] = CalcBuyTakeProfit(Symbol(),TakeProfit3,Ask);
BuyStopLoss[0] = CalcBuyStopLoss(Symbol(),StopLoss1,Ask);
BuyStopLoss[1] = CalcBuyStopLoss(Symbol(),StopLoss2,Ask);
BuyStopLoss[2] = CalcBuyStopLoss(Symbol(),StopLoss3,Ask);
We start by declaring the arrays to hold the stop loss and take profit prices, BuyTakeProfit and
BuyStopLoss. The number of array elements must be indicated when declaring the array. Array
indexes start at zero, so by declaring an array dimension size of 3, our starting index is 0, and our
largest index is 2.
Next, we calculate the stop loss and take profit prices using the functions we defined in chapter 4 –
CalcBuyStopLoss() and CalcBuyTakeProfit(). We assign the calculated stop loss or take profit
value to the appropriate array element. Note that the first array index is 0 and the third array index is
2.
Here is the for loop for placing the orders:
for(int Count = 0; Count
