how to use indicator in ea

[ilove]

can I  use an indicator's logic in an EA ? for example : i want to create an EA buy when 10 EMA cross above 20 EMA , I dont have to rewrite the whole EMA caculation instead to call the EMA paramters from EMA indicator. that way I dont have to rewrite EMA inside the EA and shorter my programming time.

The time you spent writing and posting this rambling question could have been better spent writing and testing your idea instead.

So just do it!
