Buying options contracts at mid price

If an options contract is at say 1.50 x 2.00, and I put an order in for 1.75, would that fill? Or, does the system only simulate a fill at $2.00 for a buy and $1.50 for a sell?

We use the bid (Sell) and the ask (Buy) to simulate fills for options. In other words, you would only fill if you put in an order to buy at 2.00.

Okay thanks. Makes sense, since it’d be tough to sim the liquidity of the mid.
