Important: Margin can change, and stop-loss execution is not guaranteed. Confirm current broker margin and contract details before placing a futures order.

How Position Size Is Decided

LotLogic applies two separate position limits

Risk-permitted lots

Entry-to-stop distance is multiplied by the contract lot size, then slippage and charges are added.

Margin-permitted lots

Available trading capital is divided by the manually entered margin requirement per lot.

Use the lower result

The final executable lot count is the lower of the risk limit and the margin limit.

Worked Example

₹3,00,000 capital with a 1% risk limit

Assume entry at 25,000, stop-loss at 24,950, target at 25,100, lot size 25, and margin of ₹1,50,000 per lot.

Risk budget 1% of ₹3,00,000 = ₹3,000
Stop distance 50 points
Risk per lot 50 × 25 = ₹1,250
Lots permitted by risk 2 lots
Lots permitted by margin 2 lots
Final executable position 2 lots

Margin availability does not define trade risk

A broker may allow a position based on available margin even when the entry-to-stop loss is higher than your personal risk limit. LotLogic intentionally checks both calculations independently.
