Dunn's words (he may have a little more experience than some on this forum):I'm as awake/asleep as Mr. Dunn (Dunn's system remains unchanged since 1975 - yet I hear the markets have changed due to a few recent events?): Dunn Equity Graph to 2022
But I'm certainly not playing (Play), unlike some....
Can you explain your Sharpe ratio comment in your subtext thing please? Sounds interesting.Dunn's words (he may have a little more experience than some on this forum):
We only have two systems. The first system is the one I started with in 1974. The other system, we developed and launched in 1989. The major strategic elements of these two models—how and when to trade, how much to buy and sell—have never changed in almost 30 years. We expect change. None of the things that have happened in the development of new markets over the past 30 years strike us as making the marketplace different in any essential way. The markets are just the markets. I know that is unusual. I know in the past five years a lot of competitors have purposefully lowered the risk on their models i.e., they are deleveraging them or trying to mix them with other things to reduce the volatility. Of course, they have also reduced their returns.
Nice quote. Dunn is doing very well this year. It has been a very, very, good year for trend followers.We only have two systems. The first system is the one I started with in 1974.

Almost all investors (retail in particular) are unable/unwilling to experience any investment pain (draw-downs/losses).Can you explain your Sharpe ratio comment in your subtext thing please? Sounds interesting.
It is definitive clear you are below 40 indeed.so 15y experience in a perma bull market and i assume in Australia so a perma bull country during that time.Almost all investors (retail in particular) are unable/unwilling to experience any investment pain (draw-downs/losses).
Most investment managers cater to these strong loss aversions (in order to receive sufficient funding) - hence, deploying low-risk/low-return strategies (aiming for high sharpe-ratios).
Funds (strategies) with high past sharpe-ratios are rewarded, funds (strategies) with low current sharpe-ratios are punished (i.e. sharpe-ratio chasing).
This results in a huge market opportunity in the financial eco-system, for those able/willing to experience investment pain (draw-downs/losses) - reward being overall market outperfomance.
Thus, thanks to all the high sharpe-ratio chasers, I'm set to retire when I turn 40...
(****Sharpe-ratio stated above is based on risk-free rate of return****)

So i can assume you have a great system in a perma bull market in a perma bull country.
Anyway, good on you i do not pretend i have anything like that
Well Done!I started trading in 2008.... went as well as expected.
Perma bull indeed when looking at the index, but the index itself is a trading system which will only go higher in the long term (stock selection is based on relative market-cap strength, rather than absolute price strength).
Also one of the reasons why I based my system's back-testing on long term data-sets (lots of market events included in the 1992-now AUS dataset).
The way I interpret this is that you create strategies and optimize for % return rather than smoothness (like most of us). And that the set ups relate to functions of the market that occur when the Sharpsters are out of the market. Thanks, it's worth thinking about. Although I have no idea how it might work. Any clues?Almost all investors (retail in particular) are unable/unwilling to experience any investment pain (draw-downs/losses).

Old mate Nick Radge , too , has been fearless in his honesty. More power to him for that.
That six figure number with a minus sign in front of it, just turns my stomach over.
If you find yourself in a hole, the first thing to do is stop digging.
There are some brave souls who are "proud of their ability" to suffer great monetary pains while they wait for their convictions to be rewarded.
If you can't see the problem, there is no answer.
An issue with Mr Dunn's system is that drawdowns are steep and very common. How can you tell if the system is broken? If you can tell, just how deep of a drawdown would you be in at that point? If you can't, is that not a risk that is un-managed?
@ducati916 makes some valid observations about "Dunn's Performance" since 1970
First off, I should say the rate of return is impressive & even more impressive knowing the average return of 16.63% has been achieved over a long period of time.
Compounded returns
When "compound returns" are touted & proudly displayed, I tend to switch off. I should also say, I couldn't stomach his equity curve & I believe the majority couldn't either.
How can you tell if the system is broken?
The Duc is opening a segue for another topic in my opinion. For me, the answer to this question is pretty simple, "you only realise a system is broken" when it's too late.
How do you know when the market conditions have changed?
As a system trader, it's our responsibility to keep in sync with the markets, doing so allows us to capitalise on what most don't. Allowing losses to accumulate, is certainly not the solution IMHO.

All of us have to find our little spot in the eco-system.
This statement really requires some thought.
Hi Skate. Could I trouble you to share the code for your "Final Version" of Nick's WTT Strategy?Hopefully, someone will post
There are those (forum members) who would trade Nick's WTT Turnkey Strategy. I'm hoping that a backtest will be posted for a direct comparison.
Backtest Details
$100k portfolio with a backtest period from 1/7/2019 to 30th June 2022.
My previous best effort
The previous best effort of backtesting the WTT Strategy was acceptable. To be truthful, it was a struggle to improve on the previous results.
With a little bit more time
There were areas for improvement. I'll post my previous best effort then I'll post the backtest for my final version of Nick's WTT Strategy.

Now my "Final Version" of Nick's WTT Strategy
Improvements were hard to find in the final version. The next capture below this one is a side-by-side comparison between the two strategies with red highlights.

Side-by-side comparison
The upgraded version of Nick's WTT Strategy with a direct comparison to my previous best version. The upload unfortunately is a little smaller making it hard to read.
There are improvements
Not only with the Net Profit, but also increased winners. reduction in the number of trades, lower drawdown, & better Car/MDD metric. The improvements came from adding my "Ulcer Index Indicator" to the buy condition, & passing on those riskier trades.
View attachment 143665
What is the Ulcer Index Indicator?
The Ulcer Index Indicator attempts to estimate the “stress” of a position by estimating price retracements. The indicator is based on the notion that downward volatility is bad, but upward volatility is quite good. It increases in value as the price moves farther away from a recent high price & also falls as the price rises to new highs. I hope my explanation of how I use the "Ulcer Indicator" helps you better understand why some traders are luckier than others. Indicators play a big part in my trading & they have certainly helped me. The Ulcer Indicator's sole purpose is to control the drawdown risk (not eliminate the risk) without reducing the profit potential of a strategy.
Metrics
Two areas of a backtest that carry more weight for me in deciding whether to keep developing a system, a system that you could trust trading live. (1) "Maximum System Drawdown percentage" & (2) the "Ulcer Index". Both should be low. A low drawdown & low Ulcer index should go hand in glove to give you the confidence to trade the strategy. I've previously explained how I take advantage of the Ulcer Index Indicator even supplying the parameters that I elect to use.
Finally
# I can now put this exercise to bed.

Hi Skate. Could I trouble you to share the code for your "Final Version" of Nick's WTT Strategy?
Interesting comment
Stock selection based on "relative market-cap strength". There must be something in this as @Trendnomics reported that his trading has not been affected in the last few years using this method of trading.
Further reading here
Relative Strength By Market Cap
Whenever you talk about which sectors of the market are working, market cap is one aspect that is usually overlooked.seekingalpha.com
I would love to hear more
Explaining how to find that sweet spot would make an interesting read.
Stock selection is based on relative market-cap strength
In answering @Gringotts Bank, @Trendnomics made this statement & I was expecting follow-up questions in this regard. As this is an educational thread of sorts a fuller explanation of how you go about trend trading using this method would be a great topic in itself. I'm a bit lost for words as it's all about "price action" for me.
