many orders with shared.ex4 and rocseparate...why?

New comment
 

Hello,

I'm learning mql4 and tried my first EA. I did a Backtesting. I found that my expert was sending a lot of orders at the same next bar once the buy/sell condition was given. The problem is that I programmed it to work with just one market order (i.e. system must be always buyed or selled).

 

As I wasn't be able to work it out, then I tried the expert shared.mql which is explained in the MQL4 book (with the rocseparate indicator). My surprise is that when I try a backtesting to the shared.ex4 it happens tha same. It opens a lot of orders in the same bar (and the shared EA is supposed to work with just one open order as well).

What am I missing?

 

Please help as I am a very new MQL programmer.

Thanks.

  1. No mind readers here. Do you really expect us to know what a shared.mql or rocseparate is? Or do you expect us to go looking for it?
  2. No mind readers here. Unless you post your code, we can only guess.
  3. Does those EAs automatically adjust for 4/5 digit brokers? If not did you adjust the parameters manually for your 5 digit broker?
 

I would would try it with a bool (e.g. bool OpenPositon). Set it to true after you opened a position and to false when you closed your position. 

Then add OpenPosition == false to your trading conditions. 

Hope it helps...

Shared.mq4 and roc separate,mq4 are example in MQL4 book - https://book.mql4.com/samples/shared and https://book.mql4.com/samples/iroc.

Quique, you have to modify the code so that the EA can only open 1 position per bar or open 1 position only.  There are plenty discussion on that in this forum, use search https://www.mql5.com/en/search and you will find this for example https://www.mql4.com/search#!keyword=one pe bar&module=mql4_module_forum

 

Thank you very much for your help. I'll look into every answer you gave.

 

Thanks a lot ! 

 

There is another reason that program https://book.mql4.com/samples/shared  was made in 2007 and not supporting 5 digit accounts

If you test with same settings on 5 digit account your StopLoss and TakeProfit is not pips but points  

So you will hit those settings more often...
