I observed a peculiar thing in the margin requirement for the option selling. I compared 3 broker platforms and all the 3 have different required margin amount for the same contract. Zerodha is requiring the lower margin followed by dhan. Can anyone explain why?

Great observation! Margin differences often happen due to the way different brokers handle Intraday vs Overnight limits and their own Risk Management (RMS) rules. Also, some brokers include additional ‘Adhoc’ margins for security. Hope the team explains Dhan’s calculation! 
DAMN! That’s 20% more margin on dhan and almost 40% on Fyers. i’ll have to dig deeper in this. never thought it’ll be this much variation! i thought diff. would be not more than 5-10k per lot but this is huge! i can literally short 1 lot more on zerodha for every 5 lots! this makes huge difference!
