What is Monte Carlo Simulation?
Monte Carlo simulation resamples historical trade R-multiples to estimate distribution of outcomes and drawdowns.
Formula
5th percentile curve → worst realistic equity path 50th percentile curve → median expected outcome 95th percentile curve → best realistic equity path P(drawdown above 20%) → % of simulations that hit a 20% drawdown P(drawdown above 25%) → % of simulations that hit a 25% drawdown
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 Monte Carlo Simulation shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Apply Monte Carlo Simulation for Trading Strategies to your Nifty 50 sleeve (spot near 24,300): track the metric on closed index F&O or ETF trades over at least 30 sessions before changing rules. NSE costs and slippage on fast opens often widen the gap between spreadsheet monte carlo simulation for trading strategies and bank P&L.
Reliance Industries perspective
On Reliance (₹1,300) delivery or intraday trades, calculate monte carlo simulation for trading strategies with contract-note costs included. Single-name results can look strong on monte carlo simulation for trading strategies while your Nifty-correlated book tells the opposite — tag “RELIANCE” separately in TradeLyser.
Bank Nifty futures perspective
Bank Nifty futures near 55,000 (lot 30) amplify monte carlo simulation for trading strategies swings versus cash — one volatile session can move the metric more than a week of Nifty trades. Log margin mode (MIS/NRML) with each entry for honest review.
How to validate
- Minimum sample: 30 closed trades on one strategy tag before trusting Monte Carlo Simulation.
- Check for one outlier week inflating Monte Carlo Simulation — export largest winners and losers.
- Recompute Monte Carlo Simulation after including brokerage, STT, and slippage on F&O tags.
- Compare Monte Carlo Simulation 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 Monte Carlo Simulation (or export trades to compute manually).
- Store snapshot values in weekly review: Monte Carlo Simulation, profit factor, drawdown, trade count.
- If Monte Carlo Simulation is custom, add a spreadsheet column fed from TradeLyser CSV export.
Best practices
- Publish Monte Carlo Simulation per strategy, not only at account level.
- Use the same calculation window (weekly vs monthly) year-round.
- Pair Monte Carlo Simulation with sample size in every review slide or note.
- Document formula used so mentors interpret the same number.
Common pitfalls
- Changing rules after fewer than 20 trades because Monte Carlo Simulation moved slightly.
- Mixing intraday and positional tags when computing Monte Carlo Simulation.
- Ignoring costs so Monte Carlo Simulation looks better than banked P&L.
- Letting one outlier trade dominate the Monte Carlo Simulation reading.
How to use this in TradeLyser
Run MC on 50+ closed trades per tag; note 95th percentile drawdown before sizing up.

Backtesting applies strategy rules to past data to estimate performance — subject to bias.
Drawdown at any moment is the gap between your latest equity peak and today’s equity. Max drawdown is the largest such gap over a period.
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.
Risk of ruin models chance of hitting ruin given win rate, payoff, and risk per trade.
