Close partly volume issue

[ezzakt]

Hi there,

I seem to have an issue with close partly volume in a loop

Please take a look at this screen, this is how close partly is done in this EA

Now this seems to work in Backtest. On a Demo Account its closing wrong.

This was 2 Lots initial size. Its closing 2x 1 Lot instead of just 1x 1 Lot (the Constant has 50 entered so it should close 50% of the volume)
Is there anything possible why this works fine in Backtest but not on a Demo / Live Account ?

Cheers
Andy

If you have trade with 1 lot, it should close that and reopen new one with 0.5 lot.
On the screenshot I can see opened trades, but how are they closed... or there are trades after closing...

By the way, go to Options -> Project Blocks: Normalize IDs

Thanks for the normalize IDs hint, great one ^^

I am just testing this on Demos with a colleague. We are actually confused atm, so give me some more time to test, we are not sure whats going on so I report here later

In MT4 you know you can have many trades at a time, but each one of them has fixed lot size. Closing part of it's volume is done with native MQL4 function, but it happens that the trade is first closed and then a new one is created (with volume size equal to the difference). So, if you have 1 lot and you decide to close 0.3 lots, this 1 lot is closed and 0.7 lots are openend. The newly created trade has different ticket number, but the same... I think it was the open time, or open price...

Ok this is really strange. I cannot find the error atm.

But I know what is causing the error. If I do the example with with Lot Size 2 it goes wrong, closing the full 2 lots instead of 50%

If I do the same with 1 Lot, it works perfect as we want it.

Let me write you a pm...
