Contract Value
The notional value of the underlying that one derivative contract controls.
Formula
Contract Value = Lot Size x Current Price of the Underlying
Unit
₹
In depth
Contract value is the exposure being taken, and it is the number that matters for risk — not the margin posted, which is only the deposit. A trader with ₹2,00,000 of capital holding two Nifty lots is running roughly ₹36,00,000 of exposure, or eighteen times their capital, which is the fact that most often goes unnoticed until a bad day. Position sizing in derivatives should start from contract value and the underlying's volatility, then check whether the margin is affordable, rather than the other way round. Sizing to the margin requirement is how accounts are destroyed by a two-percent move.
Worked example
Nifty at 24,000 with a lot size of 75 gives a contract value of ₹18,00,000. A 2% adverse move costs 2% x 18,00,000 = ₹36,000 — more than a third of the roughly ₹1,00,000 margin.
