Stoploss for BankNifty Buying Options

@siva-reddy @ShubhS9 @nithin

Hello Guardians,
My question may sound dumb but plz help me out.

Lets assume,
I buy ‘n’ lots of 35000 PE Weekly Expiry at Rs. 500 Cover Order / Stop Loss Buy Order
I want my stop loss at 500 which is 10%.

Can I keep it ? What is the maximum allowed % for Stop Loss in Zerodha for NFO?

Also many times when I go for Stop Loss it says it can not be placed below LTP. (When I check past posts here in this forum, it is said by you that 10% SL can be kept. Then why do I get LTP Error when placing SL for Options Buying)

Plz help. Thanks.
