Hello Peter,

You can find a code example of the routine you're looking for in this post by Alex. See Keltner(color).efs. I found this by doing a search on the phrase, color AND increas* AND decreas*. You can find a few more good posts on this topic by searching on color AND rising AND falling. If you have any trouble implementing this routine, post your formula here as an attachment rather than an image.

Jason,

tried changing the script but the color just remains green & doen't change to red when decreasing, any suggestions

Hello Peter,

There are a few corrections you need to make to your formula.

1. You have initialized vRSX in both the global and local scope. Remove the "var vRSX;" that is inside main (local scope).

2. You are using two variables for your studies that need to be initialized in the global scope (outside of main). Add the following just below var vRSX outside of main.

var myJMAstudy = null;
var myRSXstudy = null; 

3. The central problem that you have is a logic problem with your if statements that determine the color. vRSX >= vRSX-1 will always evaluate to true since vRSX - 1 will always be less than vRSX by a value of 1. You have in your code the global variable, prevRSX, that is storing the previous bar's value of vRSX. Try changing the logic in your if statements to the following.

if (vRSX >= prevRSX) setBarFgColor(Color.green);
if (vRSX < prevRSX) setBarFgColor(Color.red);

Jason,

that works fine, also would like to know if it's possible to offset a Moving Ave by .5 (1/2) standard deviation to right or left. If this can be done what is the code to use.

Hello Peter,

It is possible to apply an offset to a moving average. However, the offset value is represented by a bar index value (ie. -5 etc.). What is the data series you wanted to base the standard deviation on?

I know that I can offset 1, 2, 3 .... or -1, -2, -3...., I tried using half (0.5) standard deviation & found that this value is not applicable or can this value be used by changing the script some how

Hello Peter,

Offsets for shifting indicators left or right requires whole numbers. Advanced Charts do not support offsets by fractions of a bar. You'll have to round the number to the nearest whole number.

Jason,

thnx for the info.
