Tick volume histogram in chart window - page 2

[zzuegg]

Here you go, im feeling generous today. No warranty that it will work 100% and i am still not sure if i understand your idea:

With the external parameter you can adjust the percentage of the screen used to draw the indicator.

If you are feeling generous too you can donate something trough paypal @ [e-mail] or to your favorite organisation.

Hi zzuegg, I cant thankyou enough for your help, I will compile it and give you some feedback, hopefully it will be something I can work with.

[zzuegg]

there is still a Print() statement in the code which floods the Expert Tap, you can delete that line

I was only kidding . . . . it's not finished, it doesn't do the re-scaling.

[Simon Gniadkowski]

Made a small mod, the TickCount bars were being scaled to the same size regardless of TickCount . . . just testing now.

Looks better . . .

Huch, i have reread most of the thread, Raptor's solution might be more what you are searching for

Thankyou so much Raptor and zzuegg for all your help, just about to try it out.
