Joris, with thanks for your explanation.
My aim is to plot the vertical cursor ( why not the cross cursor )
simultaneously into the main AB window and a floating window. These two
windows display two different futures tickers, both in 5 minutes.
The code, you sent, show me features I will adapt, Dennis Brown sent me
few month ago interesting code as well.
I want to finish a book (Al Brooks - Reading Price Charts Bar by Bar)
and I'll come back to this functionality .
Hoping that TJ will implement a built-in feature someday. It's a bit
late for a Xmas' present, maybe next year...
Best regards
