What is the typical broker commission rate based off of?

I’ve been posting option trades, quantity of 50 and noticed that it comes to $59.90 total (or $1.198/contract) where is this value from and is there anyway to change it to align with the broker that I use, or set it off IB and or another option? Or is there a way to choose this that I’ve overlooked?

You can set the broker commission using a drop down under the Summary Statistics on the right side of the strategy summary page. This section may be hidden on small screen resolutions.
