Problems with EA execution in pars

New comment
  
Hello
Initially desculpelo for bad English.
I am with following problem. 
I write this code:
extern int MagicNumber=10001;
extern double Lots =0.1;
extern double StopLoss=60;
extern double TakeProfit=30;
extern int Slippage=3;

int operacao=0;
int ThisBarTrade=0;
double resetlots=Lots;
int resultado=0;

int start()
{

}





It occurs that when EA is running on more than one chart.
the OrderOpenPrice assumes the value of the opening of the last order , even if it is different chart .

Can anyone tell me how to EA interpret the data within a single chart ?
Thanks

  2. if((TotalOrdersCount()==0) && (ThisBarTrade!=Bars)) 
    Bars is unreliable (a refresh/reconnect can change number of bars on chart) volume is unreliable (miss ticks) Always use time. New candle - MQL4 forum

  3. resultado=OrderSend( Symbol(), OP_BUY, Lots, Ask, Slippage, Ask-(StopLoss/10000), Ask+(TakeProfit/10000), "Edge", MagicNumber, 0, Blue);
    Don't hard code numbers. "/10000" is the same as "*Point" except on JPY and non-currencies.
  4. You buy at the Ask, so your stops are relative to the Bid.
  5. Check your return codes (OrderSend and OrderSelect)
What are Function return values ? How do I use them ? - MQL4 forum and Common Errors in MQL4 Programs and How to Avoid Them - MQL4 Articles
  6. OrderOpenPrice assumes the value of the opening of the last order , even if it is different chart .
    Mt4 doesn't assume anything. Your TotalOrdersCount() last selected an order with the highest position.
    if(TotalOrdersCount()>0){
 if((operacao==1)&&(Ask<(OrderOpenPrice()-((StopLoss/10000)/2)))&&(OrderSymbol()==Symbol())) // compensação de perdas na compra
    Like GumRai said, you can't use any Trade Functions - MQL4 Reference until you select an order.
