Hi,

I placed the following order:  
place\_order(symbol=“AAPL”, qty=5, side=“buy”, type=“market”, time\_in\_force=“opg”)

The order was filled at **2020-06-24T13:30:07.27345Z** , with price **$365.83** , which is much higher than the true open price **$365.05** at 24 Jun, 2020.

could anyone explain why? is there a **fee** during open auction period?

Also a bit confused that the order was filled after open auction period, but it is less critical.
