Hello All,

I am learning mql4 and am struggling with one particular issue.

I have written some code that does basically the following,

i) When price reaches a zone, defined by a horizontal upper line and horizontal lower line a pending buy order is set.

ii) if price continues down to the lower line I want to delete the buy order and remove the ea

iii) if price goes above the upper line I want to remove the ea and leave the order.

The issue I am having is that when using ExpertRemove() it seems to remove all the orders.

I cannot seem to remove the ea and still leave any order on the chart,

The code Iines are attached. The rest of the code works it just when I attempt to remove the ea the issue starts.

Any advice would be greatly appreciated.

Thank you

I tried this crazy code:

void OnTick()
  {
   static int cnt = 0;
   if (cnt==0) OrderSend(_Symbol,OP_BUYSTOP,0.01,Ask*2,1,0,0);
   
   if (cnt==20) ExpertRemove();
   else Print (cnt++);
  }

and my buystop still remains...

so it's probably time you show your whole code :).

Hi Seng Joo Thio,

Thanks for the reply, I really appreciate it.

I had been working on different solutions and eventually found one that worked out well.

I'ts a bit of a work around and removes the expert at the SL and TP levels.

If a trade is not entered it is removed at SL

If trade is entered it is either removed at SL or TP, code attached.

I will have a look again and try the code you gave.

Thanks again

False. The pending order remains unless your delete it.

Removing the EA does nothing to the order. Your code must be doing that.
OrdersTotal() >= 1 && Price_A>=TP will never be true if Price_A is the Bid. The order will already have closed, and OrdersTotal() would be zero.
Using OrdersTotal directly and/or no Magic number filtering on your OrderSelect loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

Hi William,

Thanks for the advice, I have edited and added all the code.

I tried Seng Joo Thio's but the pending are still deleted.

The basic idea is to place one pending sell order, when price goes up into the zone between the Entry line and the Stop Loss Line

If price keeps going and passes the Stop_Loss_Line Then remove the Sell Stop and remove the EA

If price turns around and the sell stop is entered to remove the ea at the Take_Profit_Line and leave the order in place with SL and TP

I tried this but it didn't work and eventually I came up with the workaround in the above code.

The work around removes the expert at the SL and TP levels.

If a trade is not entered it is removed at SL

If trade is entered it is either removed at SL or TP, code attached.

The workaround is ok and allows the ea to be removed but it's not ideal.

Thanks for taking the time to comment.
