Using a value of an array from an indicator

Hi All,
I'd like to use the values that generate arrows from an indicator file. However, iCustom doesn't allow me to choose an array from an indicator.

The EA that I have set up calls to, include files so that my EA isn't long and hard to scroll and so the trading criteria include file is where I need to have the values.

I've tried to take the arrays CrossUp and CrossDown and move them to the Global Variable include file, which compiles fine, but doesn't seem to allow me any advantage in using the values.

Thanks for any assistance.
Scott

The code that I see is available in this indicator is:

double CrossUp[];
double CrossDown[];
extern int FasterMode=3; //0=sma, 1=ema, 2=smma, 3=lwma
extern int FasterMA= 3;
extern int SlowerMode=3; //0=sma, 1=ema, 2=smma, 3=lwma
extern int SlowerMA= 3;

//+------------------------------------------------------------------+
//| Custom indicator initialization function |
//+------------------------------------------------------------------+
int init()
{
//---- indicators


SetIndexStyle(0, DRAW_ARROW, EMPTY);
SetIndexArrow(0, 233);
SetIndexBuffer(0, CrossUp);
SetIndexStyle(1, DRAW_ARROW, EMPTY);
SetIndexArrow(1, 234);
SetIndexBuffer(1, CrossDown);

hi Scott
i'm not sure if i understood your problem correctly, but i assume you want to open trades based on up and down arrows draw by indicator. The simplest way to do this (in my opinion) is to use lines that are draw by this indicator - if it draw lines. If it doesnt draw anything besides arrows then you must incorporate part of indicator code into your EA, or modify indicator to insert it's MA values to buffers, so you will be able to use it in your EA by iCustom function.
I hope this makes sense, if you still have a problem post an indicator here.
regards

I expect modifying the indicator to insert the values into buffers is the likely course for me, I'll be working on that-as soon as I learn how to do it. Here's the contents of the indicator, in case anyone would like to provide some direction. Thanks, Scott

From what i see here the two arrays you are interested in are already properly mapped to indicator buffers, no change is needed.

You can use iCustom() to access any value in any of these two arrays at any time. All you have to do is call iCustom() and specify the buffer number (which array you want to read, 0 or 1) and the array index (which bar) as the two last parameters of this iCustom() call


where the barnumber is the array index (which bar you want to access), the 0 or 1 is the buffer number (which array to read) and the four 3's are the external parameters of the indicator.

Many thanks,
I guess I was just miss-interpreting the formatting in the help function.
Now on to the next step.......
