What is Profit Factor?
Profit factor summarises whether total winning rupees outweigh total losing rupees over a window. Below 1.0 means net losing; above 1.0 means net winning before you judge consistency.
Formula
Profit Factor = Gross profits ÷ Gross losses (absolute value)
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Profit Factor shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Nifty intraday strategy: gross wins ₹1.2L, gross losses ₹80k over 60 sessions → profit factor 1.5. Costs on index F&O can shave 0.1–0.2 off live PF versus backtest.
Reliance Industries perspective
Reliance swing book: ₹45k gross wins vs ₹30k gross losses → PF 1.5. Single-name concentration means one gap on results day can dominate the denominator.
Bank Nifty futures perspective
Bank Nifty scalping: PF 1.8 on 200 trades looks strong — confirm with max drawdown and slippage on 55,000-level fast markets before scaling lots.
Reading profit factor in context
Profit factor is a ratio of sums, not an average per trade. It reacts quickly to a single large loss or gain. Always inspect the underlying distribution in your journal before changing rules.
| Profit factor | Meaning | Action in review |
|---|---|---|
| < 1.0 | Losses dominate | Pause live size; audit entries and costs |
| 1.0 – 1.3 | Thin edge | Check if costs erode live results |
| 1.3 – 2.0 | Common viable band | Focus on drawdown and consistency |
| > 2.0 | Strong — verify sample | Confirm sample size and outlier trades |
How to validate
- Minimum sample: 30 closed trades on one strategy tag before trusting Profit Factor.
- Check for one outlier week inflating Profit Factor — export largest winners and losers.
- Recompute Profit Factor after including brokerage, STT, and slippage on F&O tags.
- Compare Profit Factor on the same date range as profit factor and max drawdown.
How to track in TradeLyser
- Open Strategy Board or analytics → filter by strategy tag and review period.
- Locate the widget or column reporting Profit Factor (or export trades to compute manually).
- Store snapshot values in weekly review: Profit Factor, profit factor, drawdown, trade count.
- If Profit Factor is custom, add a spreadsheet column fed from TradeLyser CSV export.
Best practices
- Publish Profit Factor per strategy, not only at account level.
- Use the same calculation window (weekly vs monthly) year-round.
- Pair Profit Factor with sample size in every review slide or note.
- Reconcile Profit Factor with broker statements before tax filing.
Common pitfalls
- Changing rules after fewer than 20 trades because Profit Factor moved slightly.
- Mixing intraday and positional tags when computing Profit Factor.
- Ignoring costs so Profit Factor looks better than banked P&L.
- Letting one outlier trade dominate the Profit Factor reading.
How to use this in TradeLyser
Open Strategy Board or analytics filtered by one tag. Profit factor should be read with win rate, expectancy, and max drawdown on the same date range. Export the trade list if a single symbol or session skews the ratio.

Expectancy answers whether your edge pays each time you repeat the setup. Positive expectancy means the system earns over many trades; negative expectancy means it bleeds even with a high win rate.
Maximum drawdown records the worst fall from a prior equity high to the subsequent low. It describes pain and capital required to stay in the game — not just the final P&L.
Profit and loss (P&L) is the change in value from trading activity. Realised P&L locks at exit; unrealised P&L marks open positions to market.
Win rate is the share of your closed trades that closed in profit after costs. It tells you how often you are right — not how much you make when you are wrong.

FAQ
Is profit factor above 1.0 enough?
Above 1.0 is positive gross edge before costs. Re-check net profit factor after fees on the same tag.
How many trades before trusting profit factor?
Wait for 30–50 closed trades per strategy tag. One outlier week can inflate small samples.
