Hey Taylor,
This is probably because you did not have that much Historical data on MetaTrader.
EA Studio offers data for 200 000 bars so your backtest there was for a longer period.
You can check how much data you have on MetaTrader if you press the home key and use the cross-hair to spot the first date.
So basically, you tested the strategies for a longer period in EA Studio and for a shorter period on MetaTrader.
