When backtesting one and strategy that is the same strategy on a chart and in [[Portfolio_Trader|Portfolio Trader]] a user might may encounter some discrepancies in the [[Using Performance Report|Strategy Performance Reports]]. To achieve similar results in both applications one needs to verify the following:
==Instrument settings==
<br><div style="background-color: #E3FBE5;">'''Important:''' Portfolio workspace should contain only 1 symbol in the [[Data_Numbers|'''Data 1''']] column!</div>
# [[Changing_Symbols|One and the same Only one symbol]] from one and the same [[:Category:Built-in_Data_Sources|data source]] should must be chosen used and they must be identical in both the MultiCharts Chart and the PortfolioTrader;
# The following parameters should be set identically:
#* Chart type - regular or [[:category:Non-Standard_Chart_Types|non-standard]];
#* [[Limit_Order_Execution_Assumptions|Backtesting assumptions]];
#* [[Realtime-History_Matching|Realtime-history matching]];
#* [[Bar Magnifier]] and [[Precise_Backtesting|Extended backtesting]] are also unavailble for Portfolio, so on the charts chart it is required to disable themthese options.
With all these recommendations met the backtesting results of Portoflio and charts should coincide.
