Back testing

 

We are currently rewriting our automated trading system using MetaTrader. Our trading system has already been written and extensively back tested using aother platform and language. We are now aiming to compare our detailed back test datas (period covered is January 2005 to July 2007 for EurUSD - GBPUSD- EURJPY - GPBJPY and AUDUSD with 1 mn interval) with our trading system built on MetaTrader. We are then looking for the best solution. Any advice is welcomed.

 
I am interested in doing something very similar. What format do you order/ save good clean reliable data in so that you can upload it into MetaTrader and backtest?
