VERY interesting discrepancy in backtests

 

In the report of a backtest, i'm getting mismatched chart errors (165,033). What are these in reference to? Does this impact the reliability of an EA or is my data (from alpari) off? The modelling quality is coming up as n/a but the entire bar is green, again, what does this say about the reliability of my backtest and my ea? (It's worth noting the backtest give phenominal results with a 200% balance increase in a year)

On another meta platform i'm using the metaquotes data (from hitory center), i'm getting 90% modelling quality, no mismatched chart errors, and the account get's blow out? What is going?

Please help me, what does this say about my EA and the discrepancy between backtests?

Thank you,

Pat
