comment mistake edit:.....plunging of Swiss frank pairs on Jan-14-2015.....

:)

Hi all, 

I back tested on XAUUSD - m5  and some other pairs, but finding the optimum params is really hard. Most of the time it is showing loss. Even if I find a set of params that shows profit, it shows loss on other periods with a max Draw down upto 97%. So it is a hit and miss thing but trading with real money on this seems gambling I prefer not to use. This is a 5 star rated bot and many people are commenting like its working perfect for them. Please share with us the best params you found out and the time period you got the profit. 

If you test any bot, dont forget to back test during the periods of the most important news like plunging of Swiss Frank on Jan-14-2015, Brexit, Trumps victory. The account is blown up with a max DD of 106%, 95% 113%. So I guess there is no money management strategy applied on this bot. 

nobulart Had worked had on this bot and I appreciate very much sharing this work with us. 

Thanks.
