Nope, you shouldn't. Here's why:
smallcase doesn’t receive your order/trade activity on Kite/Pi/Zerodha platforms, and selling a smallcase stock through any of the Zerodha platforms will not automatically reflect in your smallcase.
In this case, your smallcase holdings and P&L will be impacted and will display incorrect returns.
You have all options to manage your smallcase (invest more or exit smallcase in a few clicks, add/remove stocks to your smallcase) on our platform, so do ensure you use the smallcase platform for all smallcase-related transactions.
