Zerodha has classified IOLCP as illiquid stock in their risk management system and many smallcase users are unable to add that stock without going through the TOTP process https://zerodha.com/z-connect/tradezerodha/kite/mandatory-totp-for-illiquid-risky-contracts I am in conversation with the smallcase team on this . I will send an update soon

Please replace the NSE code of NIITTECH with COFORGE at your tracking sheet if you hold it in your portfolio
