Futures Contract Quantity Calculator
Calculate allowable futures lots based on risk budget and stop-loss distance.
How the Calculation Works
Read parameters and compute total exposure: multiply order quantity by contract unit multiplier.
Evaluate terminal return at the selected target price using strict financial mathematical boundary logic.
Deduct upfront capital commitments, taxes, or net debits to produce final net profit or loss realization.
Calculation Formula
Example Calculation
₹5L capital risking 1% with 40-point stop on Nifty (50 lot size).
₹5,000 risk budget divided by ₹2,000 per-lot risk permits exactly 2 lots.
Assumptions & Parameters
- Quantities are rounded down to conservative whole lot integers.
Frequently Asked Questions
How do I determine how many futures lots to trade?
Divide your maximum allowable rupee risk budget by the risk per lot (Stop distance × Lot size).
Can I trade fractional lots in Indian futures?
No. Exchange-traded futures contracts like Nifty and Bank Nifty must be traded in discrete whole lots.
What if my calculated lot size is zero?
If your risk budget is smaller than the risk of 1 lot, you must widen your capital or trade smaller instruments (like micro contracts or options).
How does lot size impact risk?
Larger lot sizes increase rupee risk per point, requiring tighter stops or larger capital bases.
Does lot sizing prevent margin calls?
Yes. Sizing strictly by risk prevents taking positions too large for your account to withstand.
Should I scale lots based on volatility?
Yes. In high volatility, widen your stop and decrease the number of lots traded.
