Sorry, it's not clear - does it compile without errors? If so, what happens when you are trying to add it to a chart in your MetaTrader 4? What does it say in the Experts tab log? Also, what build of MT4 are you using? You can check it via the menu Help->About...
I think this happens because there are codes that set the textfield value in OnTick or OnTimer functions. And not just Position Size textfield that's affected, the SL and TP textfields are also affected.
If you set some value in the BE field and set some color for the BE line via input parameters, the BE line will appear on the chart.
Yes, it won't work without that.
You still need to put the respective value in points in the BE field.
Thank you. Then I would need to think about something else for that, because I don't use a fixed sl and the be points would bee different every time.
Perhaps, yes, perhaps, no. Why would it succeed sometimes if that was the reason? And if that is the reason, how can it be avoided? I don't know. I will gladly accept any ideas.
This too is another mystery for me. The line gets unselected upon calling a standard library function that has nothing to do with lines. This can be potentially circumvented, but since the origin of the issue is unclear, the circumvention may just stop working. If you have some details on this bug, I will be very interest to know them.
Sorry, I didn't notice this post when posted my first reply to you. Thanks for the suggestion, but I already tracked it down to the standard library's
CWndContainer::Hide call. It has nothing to do with lines, but it still gets the TP line unselected. As I have said, I can circumvent this with a very rough workaround, but this can be some serious problem that will be manifesting itself differently.
It is same like we using ignore the other symbols Enivid. Sometimes we need to omit the current, to check what other pairs risk cost us.. So we can leave or close the other symbols.
I haven't really checked your code to confirm whether the OnTick function has logic of updating the Position Size textfield value or not, I just assumed so since I faced the same issue when I was developing my MT5 version of MQLTA OCTP, if I put updating textfield value logic in OnTick function, the same issue would happen. I'm guessing this might be a bug in MT5 platform, maybe there is a conflict issue between ObjectSetString and CHARTEVENT_OBJECT_ENDEDIT event when they happen in same time. I don't really have an idea for the solution other than don't put updating value of user-editable-textfield logic in OnTick function (if you really put the logic there).
Yeah, I'm aware it's the Hide function, this might be a bug in MT5 Panel library as it doesn't happen in MT4.
I see, that's unfortunate since this bug is quite annoying.
Please try the attached beta version. I've tried to fix this (once again) and I'm not sure how reliable this fix is.
