Subject : RE: Discrepancy between simulated and TP trades

I believe I can explain. There should definitely be no TP/broker reason why NFLX was 200 shares in OV & 300 were submitted to the broker from TP. So let's take the TP & broker out of the equation & look at the NFLX example.

On your Accounts page, looking at the simulated trades, we see that NFLX does indeed show 200 shares.



But if we look at the actual trade on the Trades page, we see that it was 300 shares at the time it was tracked/saved on 9-7.



So why are they different? The Trades page (which is what the TP uses) tracks or saves the trades each day. Once trades are Historical Positions they remain there forever (unless you reset the account). Simulated trades on the other hand are not saved on a day to day basis. You change anything in the account (setting, portfolio, etc) & the Simulated trades will update to those changes & show them instantly.

As a result, it's very difficult to get them to match especially over time. The closest you can get is to make sure the Simulation Starting Date/Balance both match your Trading Start Date/Balance & never change anything after the first day. The slightest change in the account, will cause them to never match again.

If we look at your Simulation settings, it shows that it's calculating all your Simulated Trades using a starting balance of $60,000.



But your Trading Start Balance shows $100,000.



Not only that, but your balance at IB wasn't $100,000, so after you started that account, at some point afterwards you connected your TP to it & your actual broker balance updated your Trading Current Balance. (That isn't taken into account in Simulations as Simulations just use one starting balance)

And I also see some activity where you made a couple changes in your account after you connected the TP to it, but also all the settings changes from before the TP was connected. All the changes made in setting up the account would be fine, but the important piece is that there was no account reset performed after everything in the account was finished being set up. This is something we plan to improve. Ideally we want OV to prompt an account reset after connecting a TP so that it starts the account with your broker's exact balance.

So for someone that wants to get Simulated Trades to match (which isn't really necessary, but some may choose to do so), you would need to set your OV account up exactly how you want it, connect your TP to it, then reset the account using your current broker balance as the starting balance. Going forward never change any settings or portfolios in that account. Any deviation from that will cause them to not match.
