Is there a plan to add the function
as it exists in MQL5?
It is even referenced in the example at https://docs.mql4.com/chart_operations/chartsavetemplate but seems to be not implemented yet.. :(
Although both OrderOpenTime() and TimeCurrent() are datetime types.
One gets commented as seconds and the other in date time format..
with the strict property disabled they both display in seconds.
More interesting behaviour of datetime functions.

Why not use TimeToString?

The OrderOpenTime displays int type rather than datetime in the Metaeditor. So discrepancy, you may ask for a fix.
There's a lot of examples in the docs. Like iMA taking int arguments instead of ENUM_TIMEFRAMES, ENUM_MA_METHOD, and ENUM_APPLIED_PRICE.
Yes, it is too early yet to report every glitch.
I thought int arguments were an acceptable alternative, I have always used int arguments instead of MODE_EMA etc. Also in functions like SetIndexStyle(). In the docs it usually gives the int value along side the formal identifier.

Yes, they are, but the word is about discrepancy between help and editor/compiler.
Oh I see ... yes that could cause confusion.
I have found what seems to be an undocumented feature and was hoping some one could help me fix it.
I have an EA which I have been developing for quite some time now and found unusual behavior when I added a new feature to size the chat based on historical bars. I simply get the highest high in the last x bars and the lowest low then set the chart to size this range. I have recreated an example and will post the code below. My problem is when the chart is in focus everything seems to work as planned. But when the chart in not in focus it behaves strangely, if you switch the focus to the chart it seems to be condensed at the top of the chart, then corrects on the next cycle. I don't think it is a show stopper but I found it confusing. If anyone could shed some light as to how to avoid this behaviour I would happy. I hope I have explained my problem well enough for some help.
