First, I would make sure your commissions are defined correctly in OptionVue and match what your broker charges.
Next, each time one of your live trades fill, open the T-Log and make sure the prices in OV match exactly what you got on the order confirmation from your broker.
When your trade is completely closed, OV should match exactly the P&L you have on your trading platform. I have been following the steps above and OV matches to the penny with my broker’s platform. If not, I know I have entered a price incorrectly or I am missing a transaction in OV.
Hope this helps.
