custom indicator such as MTF_Moving average AutoRefresh cannot be correctly compiled and used in the version 851 !!!!!

autorefresh

Nothing to do with 851 (you get these errors on 840 also)

int deinit()      {    return;    } function must return a value autorefresh.mq4	You can't figure out what to do about that? learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.
int    i,shift,limit,y=0,counted_bars=IndicatorCounted(); variable 'shift' not used moving_average_mtf.mq4	You can't figure out what to do about that? learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.

it's a warning message, not a error, so pass the compiler, and output is correct oin 840, i'm the user, i'm get the output, buddy
