I still don't get it :(

I've seen this error generated even when the new stoploss is equal to the old stoploss. With print statements.

OrderStopLoss() != Dynamic_Stop_Sell

I'd also ran into the thread where Gordon helped you fix it. But however I've never got order_modify to be error free.

 

The usual response I get for this error is because order modify is setting a value which already exist. If this is the case that does not explain why it dis-reguards the OrderStopLoss() != Dynamic_Stop_Sell and proceeds with the if statements when OrderStopLoss() is clearly (=)equal-to Dynamic_Stop_Sell.

 

Another reason could be because I'm entering the same Tp as what it already have. But I doubt that's the case as even the Documentation on order_modify uses the OrderTakeProfit() for tp.

 

If someone could please just add what missing within the above code so that it'll no longer generate error#1 within the back-tester I'll appreciate it. Because at this point I've checked everything I've heard of checking.

 

*NewStopLoss not equal to OldStopLoss.

*NewStopLoss > OldStopLoss

*NewStopLoss is Not within the StopLevel.

Hi uzben,

Yup, you only get the error if nothing on the order is changed, so the same TP should have no effect.

I suspect your problem is that you should Normalise Dynamic_Stop_Buy(and sell).

You could try reversing the logic a bit and trouble shoot from there :-

if(OrderType()==OP_BUY){
   if(OrderStopLoss()==NormaliseDouble(Dynamic_Stop_Buy,Digit_Info))break;
   if(OrderStopLoss()==0 || Dynamic_Stop_Buy > OrderStopLoss()){
      if(Bid_Norm > Dynamic_Stop_Buy+(Stop_Info*Point_Info)){
         OrderModify(Ticket,OrderOpenPrice(),Dynamic_Stop_Buy,
         OrderTakeProfit(),0,Green);
      }
   }
}

Actually, I am tearing my hair out with the same problem. NormaliseDouble hasn't fixed it and nor did the logic reverse.

I know the coding police will want to crucify me but I have used this simple workaround :-

if(GetLastError()==1)return(true);
The return(true) being the outcome of my OrderModify........aaarg!

Personally, I only trail my stops on a full pip move and don't get error 1

try

if(Dynamic_Stop_Buy > OrderStopLoss()+1*Point_Info)

@kennyhubbard: Lol yep, if(GetLastError()==1)return(true); definitely crossed my mind. I'll go ahead and try V's method and report back on here.

 

@Viffer: if(Dynamic_Stop_Buy > OrderStopLoss()+1*Point_Info); if this is the answer, you'll save me some early gray hair. Thanks guys for your input. I can't test this right now. Will do later.

 

Edit: V's   if(Dynamic_Stop_Buy > OrderStopLoss()+1*Point_Info); totally SOLVED the problem :)

U

And now you have fixed it I suggest you change it!

Do you really want to stack your order channel by trailing every sub-pip..?

So if this is a sub-pip, consider moving it every 10 (i.e. 1 full pip...)

FWIW

Oh, the piece of code is not designed for me. I programmed if for this thread. I don't know if it's sub-pip or not and wanted it to be flexible. I'm doing these script like EA to practice my bullet-proof coding (one size fits all). I'll leave that up to the user to decide.

On another note -BB- what do you think of my Pip/Point implementation Here

I'm glad it worked out... yeah... I am assuming Point_Info makes that 1 pip. (presumably you would have just used Point if it wasn't)

OrderStopLoss() != Dynamic_Stop_Sell

Don't not compare doubles for equality/inequality. Suppose SL=1.2345 and DSS=1.23450000001 They're not equal but you'll get a error 1.

if ( (Dynamic_Stop_Sell - OrderStopLoss()) >= Point ) // Now ok to move SL up
