How To Call This Custom Indicator ?

Rohit Sharma 2014.06.06 15:56

Dear Traders ,

Please help me to call this indicator in to an Other Custom indicator I create, some problems I face now,

iCustom(Symbol(),0,"FractalZigZagNoRepaint",ZZDepth,ZZDev,0,i) '0' Buffer For BUY
iCustom(Symbol(),0,"FractalZigZagNoRepaint",ZZDepth,ZZDev,1,i) '1' Buffer For SELL

I have Added the Indicator Code Here, Please Help me to Find Which Parameter I missed

Rock-Trader: Is this the Right way ? iCustom(Symbol(),0,"FractalZigZagNoRepaint",2,3,0,i) '0' Buffer For BUY iCustom(Symbol(),0,"FractalZigZagNoRepaint",2,3,1,i) '1' Buffer For SELL	Previously asked and answered. The indicator has three parameters. You are passing two.
