1 since MACD is indicators inside MT, so you can use these inside EA directory:

double rest=CD(NULL,0,12,26,9,PRICE_CLOSE,MODE_MAIN,0);
if (rest>50) sonuc=1.5;
if (rest<50) sonuc=2.0;
if (rest==50) sonuc=3.25;

2 double deger=iCustom(NULL, 0, "IndicatorNew",13,1,0); this is errors for this!!!!!, since parameter 13 has no menaing, parameter 1 is for one of databuffer, but no any buffer and no any parameter exist in your indicator "IndicatorNew", you only have a indicator file, but no any indicator data inside it, you should reference MTedit's help, and MQL4 language, and a lot of sample file on internet, atleast you shoul learn the samples bringed by MTself and try to modified them.

these two files only a sketch of file format of indicator and EA, but no useful contents in them.
