MA Vol EFS help

[earl540]

I tried a few ways but they did not work and could use a small favor.
When the MA is greater then 250 the background truns one colr and when less then 250 the background turns another. I have gotten real rusty. If someone could add the 2 lines of code I would greatly appreciateit. Kind of frustrated with my results.
Thanks

The code enclosed below shows you how to evaluate if the average is above 250 and color the background.
Add it to your script just before the return statement replacing your_color with the color of you choice and use it as an example to create other conditions
Alex

if(xMAofVol.getValue(0)>250)
     setBarBgColor(Color.your_color);

Worked like a charm. One more thing.

I also wanted to do the same based on the just actual volume bar over or uner 250. I replace xMAofVol with vSymbol, and it did not work. What is the correct word to put in here.
Thanks.

In that case use volume(sym(vSymbol)) in your conditions

Works perfect Thanks
