Heikin Ashi Smoothed in EA or extern as indicator?

 

Hello all,

I am searching for 'the best' option to save input variables for the excecution of buy/sell orders without any 'indicator lagg'.

I am relative new to coding and makeing bots (EA's), but i have heard to you can make a difference between an indicator loaded in your EA (And visible on the chart when you are useing the strategytester on MT4) and a different way to code where you only use the indicator code inside the EA (without showing this on the chart).

Can someone explain to me the pros and cons of the different options?

Greetz,

Rubin
