Hi Chandan,
If your broker has a demo account I would recommend creating a $10,000 demo account. Then install all robots with lot size 0.01. Then let is trade for a couple of weeks. Then look to see which robots are performing the best. Then take the three robots that are performing the best with profit factor greater than 1.2 and put them in a $1000 live account. Then each weekend look at the demo account to see which three robots are performing the best with a profit factor greater than 1.2 and put them in the live account. Keep repeating this process. This is what I am doing with one of my $2500 accounts. Over the last few of weeks the account has grown more than 1%.
Hope this helps,
Alan,
