Getting the color of the line from MA_ColorwithAppliedPrice

Hmm.. I'm having issues trying to call the MA in Color with Applied Price with iCustom. I cannot figure out how it decides the color for the line, despite looking over the source code and trying many things. It just doesn't seem to make sense. Can anyone shed any light as to how I would go about grabbing the colour for the line on the previous bar?

Here's the relevant portion of the code in the MA source:

ExtMapBuffer0[i] = MA_Cur; //red
ExtMapBuffer1[i] = MA_Cur; //green
ExtMapBuffer2[i] = MA_Cur; //yellow

if (MA_Prev > MA_Cur)
{
ExtMapBuffer1[i] = EMPTY_VALUE;

}
else if (MA_Prev < MA_Cur)
{
ExtMapBuffer2[i] = EMPTY_VALUE; //-1 red/greem tight

}
else
{

ExtMapBuffer2[i]=EMPTY_VALUE;//EMPTY_VALUE;
ExtMapBuffer1[i]=EMPTY_VALUE;//EMPTY_VALUE;
}


I've just replicated part of the code from the indy as that was quickest, with the following:

double MA_Cur = iMA(NULL,0,8,0,MODE_LWMA, 6, MAtimeperiod1);
double MA_Prev = iMA(NULL,0,8,0,MODE_LWMA, 6, MAtimeperiod2);

if (MA_Prev > MA_Cur) Comment("This is DOWN, possibly yellow");

else if (MA_Prev < MA_Cur) Comment("either UP or DOWN, but not yellow");

else Comment ("This is UP, possibly yellow");

The Comments show how little luck I've had with figuring out how it decides what colour the line is. If someone could shed some light on this I'd be damn grateful. Cheers!

Hi buddy

I think you dont need the colors for an EA... too complicated.
Just use the MA settings with shift 0 and shift 1
and the if MA previous > MA current = down as a condition.

Should be enough, no?

Hey, you're right! Why didn't I think of that. I've been pulling my hair out for an hour. Oh god. Thanks!

Funny old world, but I just had a look at the source code in order to call the values with iCustom. What I noticed was that index0 contains all values for the indicator, and is permanently plotted as a Goldenrod colour. Overlaid over this are values for index1 and index2. You can verify this by widening the width for index0 to be larger than the other 2.

So I have called all the values from index0 into my new indicator, and then performed the calculations there. Your recent conversation about Acceleration prompted this, and I figured acceleration was the rate of change of the moving average. Once you have all the values, it is easy to plot the rate of change to look at the change in velocity. And guess what? TRIX crossovers are pretty similar to changes in velocity.

I've attached the quick and dirty version from this morning.

Sent you a PM Roy

only trix not just ma1-ma2 but ma of ((ma of ma of ma)1- (ma of ma of ma)2)
