Oh, disappointing, You said option writing as well as on yesterday...that was good news.
Dear zerodha, As per my experience, Option writing is more safe than future....because if your trade gone wrong you will benefitted by premium reduction and time decay etc. and also trading cost is less.....
So please allow cover order in option writing (No need for Option buying)
You can fix range as following....
1 Price below Rs 10 SL percentage 50%
2 Price 10-30 SL percentage 30%
3 Price 30-60 SL percentage 15% Etc.
At present, only big players doing option writing, and retail traders only buying options due to high margin, some time, the big players manipulating prices of instruments
