Fxdreema not allowing to load my Indicator:

[TashaB]

I'm trying to input my custom indicator but its refusing......

[sktsec]

Check if your indicator has any buffer. Maybe it only create some objects

[TashaB]

@sktsec

beever.mq5
i've checked....i dont think the indicator is the problem, it must be fxdreema

[sktsec]

Check the source code of your indicator,

SetIndexBuffer(0,BufferPOS,INDICATOR_DATA);
SetIndexBuffer(1,BufferColorsPOS,INDICATOR_COLOR_INDEX);
SetIndexBuffer(2,BufferNEG,INDICATOR_DATA);
SetIndexBuffer(3,BufferColorsNEG,INDICATOR_COLOR_INDEX);
SetIndexBuffer(4,BufferPosTMP,INDICATOR_CALCULATIONS);
SetIndexBuffer(5,BufferNegTMP,INDICATOR_CALCULATIONS);

It seems that the last parameter in each setindexbuffer() is not defined yet. Are you sure the file is the whole source code?

Maybe you can try removing those parameters and see if the indicator works fine. Then import again.

@sktsec Actually, this is the original code;

@sktsec Still doesnt work either....

@TashaB That is a very common problem when trying ex5 files. Here you have two tutorials created to emulate the input parameters and buffers. If you can't make it after trying them that means the indicator is not compatible with fxDreema:
