Noticed one unpleasant feature of the Find-Replace option in ME881. Checked ME482, same thing there. Maybe while you are busy updating MT and fix this too?
So, in order: my code is long, for routine changes I use "Find-Replace" throughout the text. Tried to change all x1+3 to x1, seems to be ok. But my code contains lines with x1+3+3*abc. These lines instead of x1+3+3*abc changed to x1+3*abc resulted in x1*abc . And as it turns out, there can be as many of these +3's as you like, it will still be x1*abc. Rows with e.g. x1+3+4*abc change correctly.
This is a very single and rather curious case. Of course, this correction is not urgent, but I think it is necessary to avoid troubles during coding.
Doesn't work.
Although the function returns true, the object in the graph has the old name.
I don't know if this is a bug or not, but when calling Comment () in OnDeinit() the information is not displayed on the chart
example code
it means when deinitialising an EA, we can only get deinitialisation and other info via print ?
OnChartEvent
Doesn't work in the strategy testerbuild 563:
ObjectSet(labelobj,OBJPROP_CORNER,CORNER_LEFT_LOWER)
puts a label in the RIGHT corner...
Have an Alert with the name of each different MT4 instance written in it... When it pops on screen you should know which one it is.
Alert() blocks the EA/indicator...
Would be nice if MT4 alerts (from the Alerts tab) had a MQL API too.

What do you mean "Alert() blocks the EA/indicator..." ? No it doesn't. When do you want the icon to flash? When some action is performed by EA? Well, just place the alert right there in the code and be happy. :) A millisecond delay spent on giving you an Alert won't cause a major disruption, would it ? :)

Hm. Indeed it does not (just tried it in an EA). But at the same time I know I stopped using it 'cause it would block.
Anyway thank you for pointing it out.
I think there is a bug The advisor cannot call a function from the library
EA code calling the function
