What paper trading is for
| Use | What you learn |
|---|---|
| A new strategy after its backtest | Whether it behaves on live prices as it did on past data |
| A change to an existing strategy | Whether the change helps without risking money on it |
| Learning a new instrument | How Sensex options or stock options move, with no cost of mistakes |
| Practising execution | Order types, limit prices, stops and the bid-ask spread |
| Practising discipline | Following exit rules when the P&L swings |
Paper trading is one step in the path from idea to live trading: build the rules, backtest them, paper trade them, then deploy them with a small size. The paper trading meaning page defines the term, and paper vs live trading compares the two in detail.
How paper trading works in QuantPower
- Choose virtual mode for a trade or a strategy.
- Trade as usual. Place orders from the option chain, the terminal or a strategy's rules. Prices come live from your connected broker.
- See the fills. Orders fill against live prices, and positions show live P&L.
- Track the results. The strategy performance screen keeps the trades, P&L by day and the drawdown.
- Compare with the backtest. Large differences between the paper results and the backtest point to a problem in the rules or the assumptions.
- Go live when ready. Deploy the same strategy on your broker account, starting small.
Paper trading app for options: what to test
A paper trading app for options is most useful when you test what matters for options in particular:
- Strike selection. Whether your rule picks strikes you would actually trade, with tight spreads.
- Entry timing. How premiums and IV look at your entry time on real days, including event days.
- Stops on premium. Whether stops trigger where you expect when premiums jump.
- Time decay. How a position's value changes overnight and through the expiry week.
- Expiry day. How positions behave in the last hours, including the 3:40 pm close of F&O.
- Multi-leg orders. Whether all legs of a spread or condor fill close to the prices you planned.
How long to paper trade
There is no fixed period, but a few rules of thumb help:
| Strategy type | Paper trade for at least |
|---|---|
| Intraday, several trades a day | Four weeks |
| Weekly option selling on Nifty | Eight weekly expiries |
| Monthly or swing strategies | Two to three monthly cycles |
| Any strategy around events | At least two events of the kind it trades |
Long enough to see the strategy's normal days and at least one bad day. If the paper results differ from the backtest, find out why before going live.
How paper results differ from live results
Paper trading is close to live trading, but not the same.
| Factor | Paper trading | Live trading |
|---|---|---|
| Prices | Live market prices | Live market prices |
| Fills | At the market price, without your order moving it | Your order can move thin strikes, and partial fills happen |
| Slippage | Often less than live | Real, larger in fast markets |
| Rejections | Rare | Can happen for margin, price bands or freeze limits |
| Emotions | Lower, because no money is at risk | Higher, especially in losing runs |
| Costs | Estimated | Charged on every order |
Allow for these gaps when you read paper results. A strategy that barely makes money on paper will usually lose live, after slippage and costs. The brokerage calculator estimates the charges per trade.
Paper trading app in India: who it suits
A paper trading app suits Indian traders at several stages:
- New option traders learning how premiums, Greeks and expiries behave before risking money.
- Manual traders moving to automation who want to watch a bot trade before trusting it.
- Experienced traders testing a new strategy or a new index, such as Sensex weeklies on BSE.
- Traders after a losing period who want to rebuild a plan without adding to losses.
Signs you are ready to trade live
- The paper results over the full test period are close to the backtest, after costs.
- You followed every exit rule, including on the worst day.
- The worst drawdown in paper trading is one you could accept with real money.
- You know what the strategy does on event days and on expiry day.
- You have set a daily loss limit for live trading.
Start live with the smallest size the strategy allows, and increase it only after the live results match the paper ones.
What to record while you paper trade
Treat paper trades like live ones and keep the same records:
- The time, price and reason for each entry and exit.
- The bid-ask spread at entry, especially on option strikes away from the money.
- Any rule you broke or a trade you skipped, and why.
- The day's P&L and the largest open loss during the day.
- Events that day: results, policy meetings, data releases, expiry.
These notes show whether a difference from the backtest comes from the market, from the rules or from you.
Common mistakes in paper trading
- Trading larger than you would live. Virtual money makes big positions feel easy. Use the size you plan to trade.
- Ignoring costs. Subtract brokerage, STT and slippage from paper P&L before judging it.
- Stopping after a good week. A few winning days say little; wait for the full test period.
- Changing the rules during the test. Each change restarts the test. Note the idea and test it separately.
- Skipping the bad days. Stopping the strategy on a volatile day hides how it behaves when it matters.
Paper trading and backtesting
Backtesting runs the rules on past data in minutes and shows how they would have done over many market conditions. Paper trading runs them on today's market in real time, with today's prices and spreads. The two answer different questions, so a strategy should pass both.
Paper trading an options strategy step by step
Take a weekly Nifty iron condor built in the strategy builder: sell the call and put about 250 points from the index, buy wings 250 points further out, enter on the morning after the previous expiry, exit at half the credit or if a short strike is breached, and close by the day before expiry.
- Save the strategy and start it in virtual mode.
- Each week, check that the strikes chosen match what you would have picked by hand, and that the spreads at those strikes are tight.
- Note the credit at entry and the price at exit, and compare them with the backtest's figures for similar weeks.
- On the first volatile week, check that the breach rule closed the position when it should have.
- After eight expiries, compare the paper P&L, after estimated costs, with the backtest over the same weeks.
If the strategy passes, deploy it live with one lot and keep the paper version running alongside for a few weeks to compare.

Frequently asked questions
Does QuantPower's paper trading use live prices?

Can I paper trade an automated strategy?
Yes. A strategy can run as a bot in virtual mode, with the same rules it would use on your broker account.
Is money at risk in paper trading?
No. Trades use virtual money. Your broker account is used only for live prices.
Do Zerodha users need Kite Connect for paper trading?
Yes, for live prices. Zerodha charges ₹500 a month for the Kite Connect API that third-party platforms use for live data.
How long should I paper trade before going live?
At least four weeks for intraday strategies and eight weekly expiries for weekly option strategies, and long enough to see at least one bad day.
Why do my live results differ from paper trading?
Live orders face slippage, partial fills, rejections and full charges, and decisions feel different with real money at stake. Expect live results to be a little worse than paper.
