It would be a great UX experience if the below point can be considered.
1.Can we display the volume when we hover over strike price
2.Option to choose Call & Put Color or can it be defaulted to Green & Red
3.Color combination depicting volume in Option chain is difficult to interpret easily
Thanks for your feedback on the displaying the volume when user hovers over the strike price. We are also evaluating on changing the colours for the graph or even giving the user the option to change the colours as per their need.
