Trade Modification Failure

Julius Mwangi Maina 2020.05.20 14:30

Hi every one. I have to strange things I have noticed

1. Why is it my code sometimes modify position (add stoploss and takeprofit) while other times it fails?

2.Also, sometimes it will place a buy order/sell order while other times it will not..?

Anyone experience the same? Any ideas on how to go about the problems?

Here goes the code:

// Input variables
input double TradeVolume=0.1;
input int StopLoss=250;
input int TakeProfit=500;
input int MAperiod21 = 21;
input int MAperiod55 = 55;
input int MAperiod89 = 89;
input int williamsperiod21 = 21;

// Global variables 
bool glBuyPlaced, glSellPlaced;

// OnTick() event handler
void OnTick()
{
        // Trade structures
        MqlTradeRequest request;
        MqlTradeResult result;
        ZeroMemory(request);

        // Moving average
        double MA21[];
        ArraySetAsSeries(MA21,true);
        double MA55[];
        ArraySetAsSeries(MA55,true);
        double MA89[];
        ArraySetAsSeries(MA89,true);
        
        int MAHandle21=iMA(_Symbol,0,MAperiod21,MODE_EMA,0,PRICE_CLOSE);
        CopyBuffer(MAHandle21,0,0,1,MA21);
        int MAHandle55=iMA(_Symbol,0,MAperiod55,MODE_EMA,0,PRICE_CLOSE);
        CopyBuffer(MAHandle55,0,0,100,MA55);
        int MAHandle89=iMA(_Symbol,0,MAperiod89,MODE_EMA,0,PRICE_CLOSE);
        CopyBuffer(MAHandle89,0,0,1,MA89);

        //williams %
        double williams[];
        ArraySetAsSeries(williams,true);
        
        int williamsHandle=iWPR(_Symbol,0,williamsperiod21);
        CopyBuffer(williamsHandle,0,0,1,williams);
        
        // Close price
        double close[];
        ArraySetAsSeries(close,true);
        CopyClose(_Symbol,0,0,1,close);
        
        
        // Get current market orders
        ulong buyTicket = 0, sellTicket = 0;
        for(int i = 0; i < PositionsTotal(); i++)
        {
           ulong ticket = PositionGetTicket(i);
           PositionSelectByTicket(ticket);
           
           if(PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_BUY)
           {
              buyTicket = ticket;

           {
              sellTicket = ticket;
              glSellPlaced = true;
           }
        }
   
   
   // Open buy market order
   if(close[0] > MA21[0] && MA21[0]>MA55[0] && williams[0]>=-20 && glBuyPlaced == false)
   {
        // Close sell order if any
        if(sellTicket > 0)

Always the same errors again and again, what is the point to have a forum with 100,000 topics !

1. Please read the documentation AND follow it.

2. Please check on the forum about your issues before creating new topic or posting. A lot of people had already the same issues.
