different results

[pman777]

hi, I am running a backtest with a friend of mine running the same backtest on a different PC ... we both have zenfire connections. all of our parameters are identical (we've checked them several times) but our results are different. we are at a loss as to why this is happening. We are running 2/1/2012 through 6/19/2013. any thoughts?

If your signals depend on any kind of infinite impulse response filter, your charts MUST start on exactly the same bar, or you are liable to get different results. Check that you are both starting on exactly the same bar: not just the same date.
