How to pull value from another indicator for script

Hey guys, I am trying to write a script that places order and sets TP according to a value calculated in an indicator.

The indicator is TriangularMA and I have attached the copy that I am currently using and it displays three bands on the graph, the value that I am looking to use as TP is the middle band.

I have been looking around and it seems like I would use iCustom in this case? I am not sure how to deal with the parameter. Any help would be much appreciated, thank you.

You need to look at the indicator and find the SetIndexBuffer of the middle line. Then you need to look at the settings of the indicator. So lets say the indicator has parameters TMA_Length and TMA_Period (in that order, the order the parameters are in is important) with middle line indexbuffer at 2 and you want to know the value of the previous bar with TMA length over 30 bars on the current timeframe:

TMA_Length = 30;
TMA_Period = Period();
iCustom(Symbol(),0,"MA v1.4 Color Center Line",TMA_Length,TMA_Period,2,1);

Im not sure how it handles spaces in the name of the EA, if it messes up you might want to try replacing spaces with _ in both the indicator name and the name in the code.

Do I just need to put in parameter that I use or list every single one thats in the indicator?

Also what is the 1 at the end of iCustom for?

Ok i get it now , I set out the parameter first in the script, buffer is 0 and I want current bar,

Takeprofit = iCustom(Symbol(),0,"Tma v1.4 color center line",para1,para2,etc,0,0);

it's 0?

Bold part is the value you need: SetIndexBuffer(0,blahblah[])

If you have Function(int,int,int) and you switch up the integers, then, well, it won't use the right ones. It's generally best to use iCustom with ALL parameters that matter, just to avoid integers getting switched around. If you don't need integer 3, this could screw up possibly if you only fill in the first 2.

Yeah pretty sure it's 0 I will just list them all to be sure, thanks for the help much appreciated.

Got it working! Thanks

Hi

I cant seem to get the iCustom to return the same value which the indicator draws on the chart.

Drop the indicator(!TriangularMA centered bands) and EA (Test_TMA_Center_EA) on a 5 min chart.
I print a comment via the EA at the open of every new bar and display the value of the indicator via iCustom for previous bar (Bar=1)
This does not match with the values which the indicator draws on the chart.
Could you guys look into this and advice me as to what I may be doing wrong here.

Thanks

Hiii Master,

Can anyone help me, the difficulty of getting a return from iCustom TMA, the value that appears sometimes using iCustom cancle2 before.

Thank you Master.

Centered TMA recalculates/repaints
You will never get the signals that you expect just from visual inspection of the past

Thank you Master.

From the TMA I intend to use High, Low and Midle Line values on Candle current, but the resulting value is different with in Chat (when pressed Ctrl-D).

Sorry, one more why when Backtest run time is very long, the data one day about 15 minutes, on the matter of data indicator a month only 2 minutes,
Syntax: double TB = iCustom (Symbol (), 0, IndiName, 1, HLength_, Price_, Deviation_, 4.1)

Thanks.
