Thanks for your interest, kishorejoga.
I'm using a combination of EAs, most of them were tailored to my request.
At present, I have no intention to sell my EA's or disclose their logic in detail, sorry.
I'm using scalping type EA's (including MegaDroid!) on multiple currency pairs,
a martingale type EA on AUD/CAD, and a grid type EA on EUR/JPY and AUD/JPY.
