TRADE ANALYSIS

I am not sure if this request is possible within the mt4 structure, but I am looking for a script (or software) that I can use to analyze my trade performance so far this year. 

I trade manually and most of the trading guidelines revolve around on-going market sentiment. Therefore it is impossible to set up typical parameters to be backtested. The only information I can provide is my detailed trade-log, along with the account balance at the time of each trade. I would then need the script (or software) to go back and figure out the DD that occurred during each of my trades.

 Again, I do not know if this is even possible.
