Why option selling needs margin, not just premium
Buying an option only costs the premium – a fixed, known amount paid upfront. Selling (writing) an option is different: the exchange requires the seller to post margin against the position, since the seller has taken on an obligation that could result in a loss larger than the premium received. This margin requirement is what actually determines how much capital you need to run an option-selling strategy, not the premium income itself.
Real capital requirements: four live strategies
Rather than quoting a generic range, here are the actual margin requirements of four live, deployed option-selling strategies:
- Melting Premium 1 (intraday, non-directional) – ₹2,00,000
- NiftyX (intraday) – ₹2,50,000
- Weekly TimeTrap (positional, Iron Condor) – ₹3,00,000
- HedgeX (positional, STBT-based) – ₹3,00,000
The pattern here is worth noting: positional strategies (which carry overnight exposure) generally require more margin than pure intraday strategies, since exchanges typically apply higher margin requirements to overnight risk.
Every one of these four strategies publishes its own live, auto-synced performance page – win rate, drawdown, and month-by-month P&L.

Running a strategy designed for ₹3 lakh margin with less capital than that isn’t simply a smaller version of the same trade – it typically forces a reduction in position size relative to what the strategy’s own risk management assumes, or it removes your buffer against a normal drawdown entirely. A strategy’s published maximum drawdown figure assumes the account is capitalized at the level the strategy is designed for; running it thinner removes the cushion that figure assumes exists.
How to actually size your account
A reasonable starting framework:
- Match the strategy’s stated margin requirement exactly – don’t approximate downward.
- Add a buffer beyond the bare minimum – a small cushion above the stated margin absorbs day-to-day mark-to-market fluctuation without triggering a margin call mid-strategy.
- Only allocate capital you can leave in place through a full drawdown cycle – every one of these strategies has losing months in its published track record; capital you might need to withdraw mid-drawdown isn’t capital that should be deployed to begin with.
Frequently asked questions
Can I start with less than the stated margin requirement?
Technically your broker may allow it depending on their margin policy, but running below the strategy’s intended capital level changes its effective risk profile from what the published performance data reflects.
Does more capital mean proportionally more profit?
Generally, yes, if position sizing scales with capital – but drawdowns scale proportionally too. More capital doesn’t reduce percentage-based risk, it only changes the absolute rupee amounts involved.
Is there a strategy that needs less than ₹2 lakh?
Among our four current live strategies, ₹2,00,000 (Melting Premium 1) is the lowest capital requirement. Capital needs vary by broker, lot size, and market conditions, so always confirm current margin requirements before committing capital.
