1. What “LTP” Means

In any live market (like NSE, BSE, or Forex):

• LTP = the price at which the last trade happened.
  Example:

  • If Reliance share last traded at ₹2,450, then LTP = ₹2,450.

2. What an LTP Calculator Does

An LTP Calculator helps you analyze price movement and potential profit/loss based on the LTP.
Depending on the type, it can:

Basic LTP Calculator:

• Shows % change from your buy price to current LTP.
  Example:

  • Buy price = ₹2,400

  • LTP = ₹2,450

  • % change = $(2450-2400)/2400$ × 100 = 2.08% gain

Futures or Options LTP Calculator:

• Compares current LTP of futures/options to your entry price.

• Helps you track unrealized P&L (profit/loss).

• Can also factor in lot size.

Example:

• NIFTY future buy price = ₹22,000

• LTP = ₹22,150

• Lot size = 50

• Profit = (22,150 − 22,000) × 50 = ₹7,500

Advanced LTP Calculators (used by traders):

They may also include:

• Entry price

• Exit price

• Stop loss

• Target levels

• Margin requirements

• Brokerage fees

3. Why It’s Useful

• Helps track real-time performance of your trades.

• Quickly see profit/loss based on current LTP.

• Useful for day traders, F&O traders, and investors tracking multiple stocks.

4. Example in Simple Words

Let’s say you bought 100 shares of TCS at ₹3,600 each.
Now, LTP = ₹3,700.
LTP Calculator shows:

Profit = (3,700 − 3,600) × 100 = ₹10,000
% Gain = 2.78%

That’s how traders instantly check how much they’re up or down.
