Forex Profitable EA?

Hi guys,

I need your help. I wrote simple (is important) EA and I wonder is it worth to develope it more.
I have tested this EA for period 2011.01.01-now. EA has constant SL and positions opened by buystop/sellstop. Only for H4, EURUSD (but it works also with other currencies).
Just ~500 transactions.
I attached charts and data from tester. First two attachements present EA without any Money Management.
Another two pics presents this EA with MM added.

Plz give me advice, what number of positive transactions (period) you think is essentiall to think about going live ?
What other factors I should test/check to confirm it could be profitable on-live.

without MM (only trailing SL)
