I have been studying the the code for the jolly roger ea and have a few questions....    StopLevel= SymbolInfoInteger ( Symbol (), SYMBOL_TRADE_STOPS_LEVEL ); //--- set orders    if ( PositionsTotal ()< 1 && OrdersTotal

This code gives error: Ticks could not be loaded. GetLastError()=4014 I don't know why. input int       ticks= 10 ;   // the number of requested ticks

//+------------------------------------------------------------------+ //| volume                                                

In an expert adviser, in the OnTick() function , is there a way to set a global variable that will retain its value it had during the previous call? I'm looking for a variable that won't re-initialize with each new tick

I'm just wondering if there is any difference between the two lines of code below.... (for calculating the spread) 1: double Spread_1=NormalizeDouble(SymbolInfoDouble(Symbol(), SYMBOL_ASK ) - SymbolInfoDouble(Symbol(),SYMBOL_BID),_Digits);

I've read the documentation, and looked at some examples of code, but still not sure what this guy does. Help! Is it the same as _Digits

I'm just confused, it appears to me that both CTrade and MqlTradeRequest can be used to place a trade independently. Is this true? And if so, is one better that the other
