For example, SPY 141 April Call quote by C2 (usually the last traded price from real market) is 3.00
So there is a bid/ask if I look at from a real broker option chain: 2.90 bid price / 3.05 ask price.
In C2, how does the platform decides what is price to get filled and when?
Also, if I join TOS, will the filled price is like I trade in real broker like Thinkorswim or OptionXpress? Since those brokers have multiple accesses to different markets to get my limited order filled. My actual trades will get filled faster and subscribers with my system will get better filled price too?
