Hi.I´m new in the forum. I have a real trading account with Tastyworks and a paper account in TOS. In my country I can´t open a real account with TOS. Today I was comparing the bid-ask spread for the same strike and expiration in companies with volume like SBUX,CMCSA y VZ between Tastyworks and TOS and there was a big difference. My paper account with TOS has 20 min delay but I was comparing the quotes taking in consideration that 20 min delay and the difference was really big. If in TOS the difference between bid-ask was 10%,en Tastyworks was 30%... It´s possible that these 2 brokers have different bid-ask spread or they are taking the quotes from the same source? Can happen that difference because my account with TOS is paper and quotes are not accurate? Thanks a lot in advance.
They should be the same. Post some screenshots so that others can see the same things you're looking at.
