Randomly Invalid S/L

[Ngo Yung Lau]

Hi

I got some problem on setting the S/L.

The EA seems running good, but it got the error message sometime. 

Below is the example, position with the same S/L level is opened after 4 second of the Error message.

Can anyone know what happen?

Thanks

Not without seeing the relevant code!

Code is something like below:

extern double TakeProfit = 80;

extern double Stoploss = 50;

double point = Point();

   double SSL = Ask-((Stoploss)*point*1);

   double TL = Ask + (TakeProfit*point*1);

   int Ticket = OrderSend(symb,OP_BUY,Lots,Ask,2,SSL,TL,"TESTING");

You will close your buy order at the Bid, but you are calculating your SL and TP relative to the Ask. 

So you could be violating the stop level for the symbol.

This is a useful reference

Hey, thnaks for above.

But I dont really understand Bid-SL ≥ StopLevel

what is that SL and StopLevel?

To modify the code, should I just change to below for the stoploss

   double SSL = Bid-((Stoploss)*point*1);

When you subtract the the stop loss (SL) from the Bid price, the result (in points) must be greater than the stops level.

The stops level is set by your broker, and it could be different on each symbol.

Sometimes it is 0 (although that can mean 2 things). You have to check.

You can see it by pressing CTRL + U and finding your symbol:

Or you can check it in code:

SymbolInfoInteger(_Symbol,SYMBOL_TRADE_STOPS_LEVEL);

You can try. It has more chance of exceeding the stops level. But no guarantee. It is better to check the value of the stops level than to guess.
