manual back testing of "manual strategies " is a nightmare, there is not any good-reliable- accurate-robust software which works like mt4 in testing mode,
i tried several software, EA, etc. , in the market(which mentioned in Forex sites like mql5, etc), all of them have big drawbacks, hard to use, and not complete ,

i suggest to build a manual back test section which works like mt4 but with history data, and with following capability:

1- work with all pairs which history is available
2- easy to use , like mt4
3- easy to code , import, export indicators,scripts, ...
4- work with all time frame at once (not like mt4 strategy tester which works and shows just one time frame)
5- easy to share results , strategy, scripts, indicator with others

thanks a lot.
