Plus, the challenge is to find a way around the limitation. Say, prohibit redrawing of EURUSD indicator until USDCHF data arrives. Now I am testing the following variant
while(nPos > 1 || (nPos == 1 && Time[0] <= iTime("USDCHF", 0, 0)))But it all depends on how MT calculates IndicatorCounted. If by tick arrival time - it won't work, if by the fact of bar re-drawing - it will work. Let's see.
Open[1] EURUSD H1 is 1.2755
Open[1] USDCHF H1 is 1.2443
A new one hour bar appears on the EUR, nothing has changed yet on the Franc. What will your algoitm do?

Stop, stop. Here's where you write :
So we're talking about online work, and now we've jumped to a tester. I don't have time for that.

Yes, you are right. You have to watch the time of the bar, not its number.
No tester. Only online.
I have outputted it to the second file of the list of bars to be able to see the dropdowns.

The picture is almost the same for both, I will show an example on MIG.

Take for example bars 46-47.
In the second file:
45 23.10.2006 4:00 23.10.2006 4:00 23.10.2006 4:00
46 22.10.2006 23:00 22.10.2006 23:00 23.10.2006 0:00
47 22.10.2006 23:00 22.10.2006 23:00 22.10.2006 23:00
48 20.10.2006 20:00 20.10.2006 20:00 20.10.2006 20:00
Seems to be ok... But here is the problem - bar 23.10.2006 00:00 is present in history on all three currencies! I.e. it is on the chart, it is in the quotes archive.
But it seems to be absent from the indicator.
And the last trick - if you try to put a vertical line on this bar it will shift to the next bar. :о) I tried to mark it with a vertical line but it didn't work.
