Quick pointer on how this indicator rounds to 4 decimal places....

Hi

Here is the ATR indicator in mt4:

It outputs to 4 decimal places, eg: 0.0023 can anyone show me were this is set in the above code?

Thanks

I don't understand your question. What should it be if not 0.0023?

Hi

The 0.0023 is jsut an example, it always displays 0.**** which is 4 digits after the decimal point, I was wondering how it does this as I need to change it to 0.*** 3 digits, if this is possible.

Thanks

can someone help me edit sar ohlc to use heiken ashi ohlc

Hi, I have an MTF indicator that uses sar, however I'd like the sar to calculate heiken ashi ohlc, and not the normal type

Can you tell me how I can do this, my mtf indicator calls to the sar indicator to calculate sar formula, I think it is calling to the internal indicator in mt4 that can not edit

you can skype or email if you can assist and like to talk about it

I can also supply the original file that I'm trying to use heiken ashi ohlc for
