How lot size affects your trade
- Contract value = lot size × premium (options) or × spot (futures). A Nifty option at ₹150 with lot size 65 costs ₹9750 per lot.
- P&L per point = lot size × lots: ₹20 per Sensex point, ₹65 per Nifty point, per lot.
- Margin scales with contract notional, so with lot size.
