Trying to place a grid (MQL5)

New comment
 

Hi there fellow traders,

I am trying to place a grid when I open my initial position. The orders in my grid are pending orders and are increased in lot size when they get closer to my stoploss. However, the initial stop loss and take profit remain the same. I think I'm on the right path however the behaviour seems different when I'm using this system live. 

   double currentPrice = Close(0);

   double stopLoss, takeProfit;
   double grid;

   if(canOpenLong)
     {
      stopLoss = Low(1);
      takeProfit = currentPrice + ((currentPrice - stopLoss) * riskReward);
      grid = (currentPrice - stopLoss) / gridSize + 1;
      trade.PositionOpen(_Symbol, ORDER_TYPE_BUY, 0.01, SymbolInfoDouble(Symbol(),SYMBOL_ASK), stopLoss, takeProfit);
      for(int i = 1; i < gridSize; i++)
        {
         trade.OrderOpen(_Symbol, ORDER_TYPE_BUY_LIMIT, 0.01 * (i + 1), NULL, SymbolInfoDouble(Symbol(),SYMBOL_ASK) - (grid * i), stopLoss, takeProfit);
        }
     }

I have experience in coding, however MQL5 is totally new to me.

The article describes an attempt to combine theory with practice in the algorithmic trading field. Most of discussions concerning the creation of Trading Systems is connected with the use of historic bars and various indicators applied thereon. This is the most well covered field and thus we will not consider it. Bars represent a very artificial entity; therefore we will work with something closer to proto-data, namely the price ticks.

search the site for Invalid Stops.

And since that there is no definition of riskReward, how can we help?
