I try to convert indicator to Expert Advisor

I have indicators and want to convert expert using indicator, I added some line to indicators. When load the expert meta trader give message like ""Expert 'aydin_expert' is an indicator and cannot be executed""
I attached the expert file please help where is my mistake.

You can also try to the use the iCustom function.... you use it just like you can call iMA(), passing it the symbol, timeframe, name of your indicator, and a list of the external parameters That way you can keep your indicator code separate from your expert advisor.

From the Metatrader help file:

double iCustom( string symbol, int timeframe, string name, ..., int mode, int shift)

Calculates the specified custom indicator and returns its value. The custom indicator must be compiled (*.EX4 file) and be in the terminal_directory\experts\indicators directory.

Parameters:
symbol - Symbol the data of which should be used to calculate indicator. NULL means current symbol.

timeframe - Timeframe. It can be any of Timeframe enumeration values. 0 means the current chart timeframe.

name - Custom indicator compiled program name.

... - Parameters set (if necessary). The passed parameters and their order must correspond with the desclaration order and the type of extern variables of the custom indicator.

mode - Line index. Can be from 0 to 7 and must correspond with the index used by one of SetIndexBuffer functions.

shift - Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago).

Sample: double val=iCustom(NULL, 0, "aydin_Indicator", param1, param2, paramX, 13,1,0);

Does anyone have example code of a simple indicator and an EA that calls that indicator using the iCustom() function so I can see exactly how variables are passed from the indicator to the EA?

Any help will be greatly appreciated.
Thanks.
