The contract or spread mid price is the price between the bid and ask prices currently on offer for the option contract or the spread. This is a good target for a limit price placed on an options order.
The contract or spread mid price may be added to your Brutus Options Ranker strategy if you have a specific price you'd like to stay close to when executing your order.
We recommend only using this criterion in target mode. E.g., if you would like target contracts or spreads that have premium around $2/contract/spread.
We do not recommend minimizing or maximizing the mid price unless coupled with more heavily weighted criteria to ensure that proper underlying and options liquidity are considered as part of the strategy.
