Change the sample and test cost. All totals use the completed trades below. Gross means before costs. Net means after costs.
A leg is one option position. Each leg uses 50 example units. Entry is at 09:30. Costs cover opening and closing both options once. These are test costs, not broker fees.
- Profit or loss after costs
- ₹520
- Largest fall
- ₹1,840
- Winning trades
- 57.1%
- Completed / skipped
- 7 / 1
Gross ₹800− Costs ₹280= Net ₹520
Net equity is the total result after costs. It starts at zero. Drawdown shows each fall from an earlier high after completed trades. Largest fall is the highest drawdown. It excludes losses during open trades. A winning trade has a profit after costs.

Sell 24,000 CE at 126; Sell 24,000 PE at 112. CE means call. PE means put. We set all sample exit times in advance.
We made up these trade records. They are not market prices or past market results. This sample shows how we calculate reports. It does not test past market data or apply your own risk rules.
Check each trade.
See when each trade opened and closed. Check its prices, quantity and exit reason. The example shows both option prices so you can check the result.
Check the largest fall.
Drawdown is a fall from an earlier high in your results. Check these falls as well as the final profit. A profitable test can still have large losses along the way.
See where data is missing.
See which dates passed, failed or could not be tested. A missing price is not zero. Check how many trades had enough data before you compare results.
Include the costs.
Profit before costs is not the final result. Change the example cost per trade. The chart, final result and number of winning trades update together.

The option price you receive limits your profit. A large index move can cause a large loss.
A leg is one option position. Strike is the fixed index price used to calculate the result at expiry. Premium is the option price. Expiry is when the option ends. Breakeven means no profit or loss. Each leg uses 50 example units. Costs are excluded. This chart shows the result at expiry. It does not show current option prices or actual lot sizes from past dates.
Build the complete position.
Combine buy and sell positions. Set the quantity and holding period. Use contracts with checked data in the same strategy.
Test the exit rules.
Set a stop loss, profit target and trailing stop. Limit repeat entries after an exit. Apply rules to one leg or the full strategy.
Separate the results.
P&L means profit or loss. Check open positions, closed trades and costs separately. A payoff chart shows possible results at expiry. An MTM chart shows how the result changes over time.
See where a loss can occur.
Move the index price in the example. Compare the three strategies. A breakeven is a price where profit and loss are zero. Costs can change that price.

5 sample contracts
Volume counts traded contracts. OI means open interest: contracts that remain open. V/OI means volume divided by OI. These counts do not show whether buyers expect prices to rise or fall.

Volume divided by OI is 0.40× at this sample time.
Each step shows the next price. OI stays at its value for the sample time. This sample does not create orders or calculate profit or loss. This is made-up data, not market prices.
Check each contract.
Know the limits.
Recorded prices do not show every buy and sell order. Test results depend on the available data, trading costs and order rules.
We check each contract, its lot size and its official settlement value before we allow trades for that period.

Learn what you can test before you start.
Getting started
Can I use TradeOnLogic now?
The full app is not open to the public yet. You can try the examples on this website. Their prices are made up. They are not market data.
Which markets will I be able to test?
We plan to include NIFTY, BANKNIFTY and SENSEX options. Available dates and contracts will depend on our data checks.
What is market replay?
Market replay lets you move through a past trading day. You can add a position and see its profit or loss as time moves.
Can it place orders with my broker?
No. Live orders through a broker are a future plan. We are working on tests with past data first.
Testing a strategy
What is a backtest?
A backtest tests your trading rules with past data. You set when to buy, sell and exit. The results show trades, costs, profit and loss.
Can I combine buy and sell positions?
Yes. We plan to support up to eight legs. A leg is one buy or sell position in your strategy. Each leg can have its own risk limits.
Can I hold a position until expiry?
Yes, for dates with checked contract and settlement data. Expiry is the date when the option ends. We need the official settlement value to show the final result.
Does a good backtest mean I will make money?
No. Past results do not guarantee future profit. A test uses recorded prices and rules for costs and order prices. Actual trading results can be different.
