Same Backtest - Different Results

Hi,

A friend and I are trying to run the same backtest and we are getting wildly different results. But not for the reasons you'd expect like choice of broker, latency, commissions, currency pair, tick frequency, user time etc. We're both set to UTC+1, both using IC markets and the cBot we're running is programmed using UTC+1. He is based in Aus and I'm based in the UK but that wouldn't explain why my chart doesn't show anything remotely looking like the NFP action on 2nd July 2015. Please could you advise? Please note that I have already tried deleting the cache and I have also tried uninstalling and re-installing cAlgo.

Thanks,
