Some charts would be good

Hello friends,

Even after correction and pasting here it shows some errors. In this regard you have to paste in the formula editor and remove spaces with the help of VERIFY SYNTAX.

pl explain the setup. what it does? i see 4 EMA and 1 MA. cross over of EMAs with MA is the signal? ho do you handle whipsaws? on what time frame it works? did u test beteen jan - mar 09 ?

This corrected afl did not work
