Punch's default spot chart is based on trader feedback, serving as the primary reference for trading. It integrates strike plotting, call and put pricing, and direct trading.
After consulting with hundreds of traders and experts, we found that while users trade on option price charts, they primarily use the underlying spot or index chart as the main reference.
Setting the spot or index chart as the default allows us to integrate strike plotting, call and put pricing, and trading directly from this chart.
