What I have been hoping for is to get sharpe (or even better sortino) ratio as one of the result parameters from tester. Do you have any plans to add it (or any other profit/volatility ratio)?

Also, will it be possible to still handle trades as one trade instances? I mean that there will be a way to manage one part of a trade in one way (for example different tp and sl) and part of a trade in different way (other kind of method of managing tp and sl) or will tp and sl work in same way as in ECNs, as separate buy stop/sell stops?

Also, will we be able to use mql4 (is the client backward compatible)?
