In my Fyers account CO and BO order not working for option trading. can anyone suggest me how to enable BO and CO order for option trading ?

Hi @Ramesh Solanki18,

BO/CO is disabled in Fyers due to the discontinuation of SL-M orders by the exchange. 

Thanks!

cover order (co) and bracket order (bo) is blocked by SEBI in all broker these orders are blocked for option trading
