One of the biggest challenges faced by futures and derivatives traders is determining the actual profit or loss from multiple buy and sell transactions spread across different trading days and contract expiries. Most brokers provide detailed transaction statements, but extracting meaningful insights such as realized profit, unrealized profit, open positions, average purchase price, and FIFO matching often requires manual calculations or specialized software.
This article presents a practical case study based on an anonymized trading account to explain how transaction statements can be analyzed to determine trading performance accurately. All stock names, trader names, account details, and quantities have been modified for privacy.
A broker's transaction statement generally contains:
While these values are useful individually, traders often need consolidated information such as:
Consider a trader who performs multiple trades in the same futures contract.
Example:
At the end of the month, only some positions remain open.
Questions arise:
Without proper matching logic, these calculations become confusing.
Professional accounting software and many brokers use the FIFO method.
FIFO assumes:
The earliest purchased shares are sold first.
Example:
Buy
Sell
Calculation:
First
500 × (270−250)
Then
200 × (270−255)
Remaining holding
300 shares @ ₹255
FIFO provides transparent and audit-friendly calculations.
After processing every buy and sell transaction, the remaining unmatched buy trades become the current holdings.
Example:
Buy
400 @ ₹920
Buy
400 @ ₹924
Buy
400 @ ₹930
If only the first two lots are partially sold, the remaining unmatched lots become the current portfolio.
This is known as the Open Position.
Realized Profit is generated only when a position has actually been sold.
Formula:
Realized Profit = Selling Price − Purchase Price
multiplied by Quantity Sold.
Example
Buy
800 @ ₹960
Sell
800 @ ₹975
Profit
₹15 × 800
= ₹12,000
This amount is locked and cannot change.
Open positions fluctuate with market prices.
Formula
Current Market Price − Purchase Price
Example
Bought
800 @ ₹960
Current Market Price
₹968
Running Profit
₹8 × 800
= ₹6,400
This profit changes every second during market hours.
Many traders prefer seeing average purchase cost.
Example
Bought
500 @ ₹950
500 @ ₹960
500 @ ₹970
Average
(950 + 960 + 970) / 3
= ₹960
Although FIFO remains necessary for accounting, average cost provides a quick overview of current holdings.
Ignoring brokerage can give misleading results.
Actual net profit should include:
Formula
Net Profit
= Gross Trading Profit
− All Charges
Professional traders always evaluate their strategy using net profitability instead of gross gains.
Futures contracts have different expiry months.
For example
ABC JUL Futures
ABC AUG Futures
Although both belong to the same company, they are separate contracts.
FIFO calculations should never mix different expiry months.
Each contract must be processed independently.
Modern portfolio analysis software can automate:
Automation eliminates manual calculation errors and saves significant time.
An advanced trading analysis application may include:
Many traders unknowingly make these mistakes:
Professional traders should:
Accurate profit and loss calculation is far more than subtracting the purchase price from the selling price. A complete trading analysis requires proper trade matching, contract-wise tracking, brokerage adjustments, and continuous monitoring of open positions.
By using FIFO methodology and automated analysis software, traders can obtain reliable realized and unrealized profit figures, reduce accounting errors, improve decision-making, and simplify tax preparation. Whether managing a small personal portfolio or executing hundreds of futures trades every month, systematic transaction analysis is an essential component of professional trading.
