Please see the following screenshots

Screenshot 1 is the normal display where in you display the calls strike price and if you select Put it will display the Put Strike price and its details

Screenshot 2 is my modifies Chain which will be used as reference in this thread

Here are the Use cases

In the screenshot All is in Orange color, meaning its the active selection. If the user clicks on Puts or Calls , it should toggle to Active selection color accordingly

Case 1:

Step 1: Initial Load up of this form for the first time

Screenshot 2 All button is highligted is displayed in the format shown, witj Limited information

Step 2 : If the user want the main charts to be loaded with either Call or Put charts with any strike price of his selection he will just click on the Call side row of the call strike price and the main charts will be loaded (Exisiting functionality of the app)

Step 3 If he wants to select any put side strike price , he just selects the row of the relevant put strike price row and that gets loaded on to the main chart

Case 2:

Step 1 : User selects Calls (The “Calls” Button beside “ALL” Refer my screenshot) and the exisiting screen which you have in place is dispkayed with Additional Information like Price Chg%, OIl(l) and OI% is shown and the same exisiting functionality of the loading that particular strike price on to main chart will follow

Step 1 : User selects Puts(The “Puts” Button beside “Calls” Refer my screenshot) and the exisiting screen which you have in place is displayed with Additional Information like Price Chg%, OIl(l) and OI% is shown and the same exisiting functionality of the loading that particular strike price on to main chart will follow

Advantages:

Assume if the main charts has an active strike price of call 25950 and the user immediately want to load 25400 PE. Your App loads the default screen which shows Call strike price. Then the user has to switch to Puts and then selects the strike price , where he loses valuable time , if he is ascalper

Best would be show the modified screenshot which I have given or similarr one , where in the user can directly select call or put strike with ease , without switching to multiple screen
