Now the part of the ea causing this is right at the start of the code :
Code:
string TradeSymbol; TradeSymbol=Symbol();
If I block this out it comes up with errors for the following bit of code :
Code:
if(TotalTradesThisSymbol(TradeSymbol)==0) { int BS=0,SS=0,BL=0,SL=0; }
if(TotalTradesThisSymbol(TradeSymbol)>0) {
for(cnt=0;cnt<total;cnt++) {
OrderSelect(cnt,SELECT_BY_POS,MODE_TRADES);
if(OrderSymbol()== Symbol) {
if(OrderMagicNumber()==11) { BS=OrderTicket(); }
if(OrderMagicNumber()==22) { SS=OrderTicket(); }
if(OrderMagicNumber()==33) { BL=OrderTicket(); }
if(OrderMagicNumber()==44) { SL=OrderTicket(); }
}//end if(OrderSymbol
}//end for
}//end if */
What I am wanting to know is if there is an easy way to fix this.
I'm no good at coding , only copying and pasteing.
Thanks in advance

You can define TradeSymbol as string on global scoop, but there you cannot evaluate the function Symbol(). So replace all "TradeSymbol" by "Symbol()", or assign the value in the init() or start() function like this:
PHP Code:
void Init(){TradeSymbol=Symbol();}
