How the Calculation Works

Step 1: Input Valuation

Read parameters and compute total exposure: multiply order quantity by contract unit multiplier.

Step 2: Payoff & Boundary Evaluation

Evaluate terminal return at the selected target price using strict financial mathematical boundary logic.

Step 3: Frictional & Premium Netting

Deduct upfront capital commitments, taxes, or net debits to produce final net profit or loss realization.

Calculation Formula

Long Trailing Stop = Peak Market Price × (1 - Trailing %)

Example Calculation

Stock surged to ₹600 peak with a 5% trailing stop.

Outcome: Active Trailing Stop: ₹570.00 | Locked Gain Protected

Stop ratchets upward to ₹570, locking in previous gains.

Assumptions & Parameters

  • Trailing stop moves only in the direction of trade profit; it never moves backward.

Frequently Asked Questions

What is a trailing stop?

A stop order that automatically adjusts upward (for long positions) as price reaches new highs.

What is the benefit of a trailing stop?

It lets winning positions run during strong trends while locking in accumulated profits if the market reverses.

How tight should a trailing stop be?

Too tight (e.g. 1%) leads to premature exits; too loose (e.g. 15%) surrenders too much open profit.

Can trailing stops be based on moving averages or ATR?

Yes. Many traders trail stops using 20 EMA or 2x ATR instead of fixed percentages.

Does this calculator execute automatic orders?

No. This tool calculates stop levels mathematically for order entry in your broker terminal.

How do trailing stops work on short positions?

For short trades, the stop trails downward behind lower lows: Trough Price × (1 + Trailing %).
