Add Option Buyer/Seller Logic for Accurate P&L Calculation in Entry/Exit

Being an option seller myself, I would gain upon decrease in option price (for Upside & downside moves) . Hence, I would always have to select "Short" over here for both upside and downside trades.

Can we add a logic to select "option buying/selling" as well and calculate the difference between entry & exit accordingly.

As a result, below diagram will only show "Shorts" though i took both upside & downside trades
