Using Information of an Custom Indicator

[Deleted] 2009.03.10 11:33

Hey everybody,

i would like to use some information of this custom indicator. I need to know, how to get the collours out of this indicator in an EA.

I tried to use icustom, but this one gives me only the value of the indicator. is there another way to get some variables out of the indicator,

so i can use it for an ea? (some kinds of global variables, which can be declared in the indicator and than be used in the ea?)

thanks for help

i'm not going to analyze the code, but, read in all values with iCustom, and look at the correlation between how values change and how colors change. In the HMA indicator, to read the colors, i had a reading of 0 in one array, and an integer in another array, so (0, 1.28) that is red for example. Now when you have an integer in first array, and a 0 in the second array, that was blue, (2.12, 0).

So (0,x) is red, and (x,0) is blue. Look for these patterns.

Work with these arrays:

#property indicator_color1 Orange
#property indicator_color2 Aqua
#property indicator_color3 Magenta

TTM Squeeze/BB Squeeze Indicators with alerts/signal Help me!!!! Why this
