You can pledge your holdings in Zerodha (even Mutual fund units - after transferring it to Zerodha Coin).
This can reduce your margin requirements to roughly around 60%.
Buy NiftyBees and LiquidCase in 50:50 ratio and pledge it for option selling margin if you’re not already doing that. Easy 8% ROC in addition to your option selling profits.
Rules require cash margin of 50% so the ratio can’t be more in favor of equities or gold.
If you’re hedging to reduce margin requirement, you’re probably doing it wrong (over-leveraging)!
