Is there a TOS indicator out there (or anywhere else) that shows what an option should be worth intraday when the underlying hits a certain price. What I mean is prior to the start of a days trading, is there a place to find what a liquid actively traded option should be worth if the price hits a certain price during the day. i.e. a stock starts the day from the previous close price of 50 and I want to buy a specific strike and month option if during the day the price hits 49. Is there a way to know what that option price should equal if it hits 49 so that an order could be placed without having to watch the market all day? Thanks for any input in advance.
