Top tips from this episode
Here are few of my favourite takeaways from the chat with Alan this week:
- Dynamic position sizing using Monte Carlo analysis – when live trading use a moving window of trades by feeding in the most recent trades into your Monte Carlo engine and using that to determine the position size for the next trade. The advantage of that is a reduction in position size when the system is in drawdown but also increased position size when the system is going through a profitable run.
- Trading based on system health – you can monitor system health by comparing short-run statistics to long-run statistics, using a rolling window of the most recent trades and comparing the results to the longer-term backtest results. Establish a limit where you will stop taking trades if performance degrades by a specific measurement, whether it be drawdown level, win %, consecutive losses etc. When that point arrives you stop taking new trades but continue to monitor how the system would have performed if you’d taken those trades, waiting to see if the system comes back into the sync with the market and pops back up above your limit point, in which case you can start trading the system again.

Fantastic episode but I was confused by one point that Alan made when he was discussing position sizing alternatives.
Alan suggested that one could use Monte Carlo Analysis for dynamic position sizing by feeding a rolling window of the most recent trades into a MC Engine and using the results to determine the position size for the next trade.
Why wouldn’t you just use the actual results to either scale up or down your position size? If you are on a winning streak, you are on a winning streak and can lever up; how would MC Analysis change any of that?
Sorry if the question seems naive and thank you.
Hi Brian, here’s a response from Alan:
“What we are trying to determine is the potential for our system’s drawdown to exceed our own personal threshold within a given probability, and then using that to determine the position size. The best way to determine that probability is through a Monte Carlo process, which will provide a distribution of potential outcomes.
We are still using the actual trade results as inputs. A winning streak of late will produce a lower probability of a large drawdown, allowing us to increase the position size, and a string of losers will produce a larger probability of a large drawdown allowing us to calculate a smaller position size.
Since we have no way of knowing the future order of winners and losers in the system, we can only work off probabilities, and it’s MC that gives us that ability.
For more study on this, I can recommend Howard Bandy’s book Quantitative Technical Analysis. http://www.quantitativetechnicalanalysis.com/”
Cheers,
Andrew.
Hi Andrew,
