Backtest Signal with fixed expiry time.

Hello. I need help/system to backtest any signal from history trades (http://www.mql5.com/signals) with fixed expiry time.

Has to work for both MT4 and MT5 signals. 

Based on the History Trades the system have to:

1. Find the opening price on the asset with my broker/pricefeed with the same time as Signalprovider. To check the slippage.

2. Find the closing price on different fixed expiry times. (ex: 2, 5, 10, 15 , 60 min etc)

3. System have to be able to handle multiple currency/pairs at the same time. (The same as the signalprovider)

 Spesifications:

 System have to check:

a) Signal open a new positon/trade = find the closing prices with fixed expiry times

b) Signal close a old position = do nothing 

Requirements:

The history trades can be downloaded to a .csv file.

System has to filter out and use only "opening signals"(going in). ("Closing signals" will be irrelevant to my system.)

System has to plot a new .csv files with the result of the backtesting for further analyze. 

(or alternative; a good UI inside Metatrader? )

I can send spesifications on what kind of information I want.

System also has to work on MT5 signals!

I am also open for other soultions for this side-step project?
