Strategy Performance Report
Posted: 24 Apr 2010
When I'm running an automated strategy, and I compare the daily period results with what is actually happening with my account in IB, the results are fairly similar. However, if, at the end of the day, if I close my workspace and then open it again (i.e., it goes into backtesting mode), the results for that day change (and are often markedly different from what actually happened).
In other words, let's say I'm running an automated strategy and at the end of the day, before I close it, my performance report says there is a profit of X. If I close the workspace and open the same one again and check the performance report, the daily profit will have changed (to X +/- Y). Nothing has changed in the strategy (i.e., code, settings, etc. are exactly the same). Can someone help me understand why this is happening? Thanks.
