Woodie CCI

[brianb]

I like the combining of 4 efs into 1 nice and versatile one but I can't stand the values that show up in the title (which is edited to read cci in the attached chart.) If any changes are made to this efs the result is that huge overlay that potentially blots out chart information. Can something be done to eliminate or at least minimize this?

Description: The Woodie CCI is two CCI studies overlayed on each other.
The main line in blue is a 14 period CCI based off of the High, Low and Close / 3.
The secondary line in red, commonly referred to as a Turbo CCI, is a 6 period CCI
also based off of the High, Low and Close / 3. Also, added to this study are 3 lines
added at 200, 0, and -200 for reference.

Version Control

1.1 -- Added Support for a 34 period CCI, and the ability to turn features on/off
in the Edit Studies window. Please note that 3rd CCI is the study that contains
the histogram.

If using 7.4 RC4 you have an option to hide all the study titles in a chart. To do this right click on the chart, select Properties then uncheck "Draw Study Titles".
Another option is to reduce some of the FunctionParameters in preMain(), in particular the ones used to set the colors (fp7, fp8 and fp9) as they return a long list of numbers in the study title.
Just some ideas

Thanks for the tip Alex. I'm using 7.3 and look forward to this new feature. Hope it works on basic studies as well as formulas.
