Many of which suffer from natural mean reversion. CAPE has a good record of market timing over the last years which is why it has become such a popular tool. Buy the selected items together This item: If your equity curve starts dropping below these curves, it means your system is performing poorly. The idea is that you buy more shares when volatility is low and fewer shares when volatility is high. Use it to improve both your trading system and your backtesting process.
Considerations for mean reversion trading systems. Risk Control. One of the major problems with mean reversion trading systems is risk control. A mean reversion trader sees a market that has dropped from the average as cheap; the problem is that if the market continues to drop, it becomes even cheaper.

Now, low commissions, on a relative basis to the equity markets, have been a fact in the futures markets forever. And trending has survived there. My sense is we saw a shift in equities because of the market structure shift, and that it will stabilize again once the MR money is arbed out — which it appears to be doing.

Mean reversion strategies have been very popular since Some use the RSI indicator, some use a short term simple moving average, some use boillinger bands, etc. The concept is the same: Anyway, thought I'd share a connection to you past work. BTW, you should still post insights here despite being with LogicInvest. Leave a Reply Cancel reply Your email address will not be published.
First, I have not tested the short version of this. The inverse rules changes are Setup changes would be Close MA5. I find it interesting that this person was able to program this strategy, generate the results and test them in less than half a day.
Originally, when you gave the rules the option I gave you was not included. This is what you gave:. Your post that this must be included has a time stamp at least 3 hours after my post.
I do not see a reason for omitting it in the first place because it deals with exactly the issues raised. Therefore, one way for you to prove that your results are correct is to post an excel file of the Amibroker trade-by-trade output for the first case of Russell Then the issue will be settled either way.
You may have something here but the odds are against you and you possibly either have optimized the system to fit past data or you have a bug that overstates CAGR. The reason for the omission is I missed that one line of code when I copied over what I wanted to show.
Since you have had someone code it up, you can verify for yourself if the results are correct or not. As far as I am concerned, these results are correct as I stated I had a another person code them up and get exactly the same results. I appreciate you bringing up your concerns that the code was wrong but I have proved to myself there are no issues.
I will only spend more time and energy on this topic, if someone brings proof that the results are wrong. This strategy is in fact an intraday strategy, not interday.
You might have many stocks that meets the criteria on given day. In real life however, you would only buy these stock, that will go down earlier. Having EOD data you do not really know, which one you will buy. That is why you need to use MonteCarlo. Lets suppose, that on given fay 5 stocks meet criteria and goes down by at least 5 percent. MonteCarlo assumes that the distribution of probability is uniform. Other words, you will buy good stocks in 4 cases and the bad one in 1 case. And what if bad stock almost always goes down quicker that good stock?
That will mean, that the distribution of probability is not uniform. And the test results are not reliable. I am asking the question, because I created similar mean reversion strategy, but this question worries me. I did do a Monte Carlo simulation on these results. We do not know which stocks trigger first. You are correct that we do not know if bad stocks tends to trigger first or not, thus the distribution is not uniform.
I ask becuase it seems every time I attempt to code a limit order in amibroker I get a Holy Grail outcome! The reason you end up with a Holy Grail system is that there may be signals and your system like this one, takes those that signal.
In most peoples real trading they are not sitting in front of the computer to see which ones trigger first and then entering those. The more likely case is that one places limit orders for the first 10 ranked stocks. But then these may or may not get filled. Thus you end up with a much lower exposure and lower CAGR. If you have many signals on one day. That way you will always buy the stock, that first triggers on the limit.
However, you will buy a maximum one stock daily, On the other hand, if you have stocks with signal and if you place orders for 10 of them, you might buy nothing.
Also, thanks for sharing this very hard work you have done. It seems no good deed goes unpunished. Results improve considerably when the requirement that the price be above its day moving average is removed. I have had several people email about suggestions on how to improve the strategy or make it easier to trade.
I will likely do a post on that in the future. I will remember to test by removing the MA rule. Good work but needs some checking. Cesar, I ran the data as per your adjustments back to using delisted and historical constiuents to alleviate survivorship bias this also offrs some out-of-sample data as your test started Results as follows Original vs Adjusted:. Certainly a significant outperformance, but coming with greater downside.
It can be done. Interesting to see these results. I agree it can be done. It just requires some experience on order placement from the user. Therefore I would personally not remove the day MAV. I feel I am missing the point, but if you start your tests on a given date, why must you run separate tests? Is this because the random parameter leads to different results each time? I use these two lines: This post will cover three of […]. I backtested this strategy myself, I can comfirm the results above.
It seems there is no survivership bias involved as there are good results on random portfolios as well. You can increase the return even more with a same-day-exit on close, althoug that rule makes it even less tradable manually.
This strategy needs automatic execute anyway…. Hi Cesar, i could not find any information in your describtion neither in the comments regarding initial stopp loss.
What value did you use for that? Thanks for all this great and interesting materials. Is it 3 LLV in a row? Is it 3 LLV over a certain period? If not on a close, then on what? I can personally verify that this strategy works in practice. I have been trading a very similar method to this constantly since April I trade much smaller on each position and trade it globally on Interactive Brokers. Max drawdown was My thanks particularly to Cesar as I was a longtime paying student of Connors research and all my methods are based on them.
David, thank you for the kind words. It is good to hear that your strategy is doing great. I use Tradestation so ask. That is what a lot of people do. I have not found a trend following strategy that I like. I do trade multiple strategies with the same general idea that one is at least working at all times.
But remember, when markets go to hell correlation goes to 1. Thks Cesar for posting this strategy. I am going to try the same like what Dave said here. Thanks for a great contribution to mean reversion trading MRV. This is a very valuable work that I highly recommend.
I am wondering whether MRV works as well with Forex or futures markets. Do you have any experience with this? First let me say I am not a Forex or futures trader. What little testing I have done in these markets, MR seems to work on the futures market and not as much on Forex. I have entered my information so you can send me the link to your spreadsheet.
I think there are so many trades that fit the criteria 3 lowest lows, etc. I got the same good results until I turned same bar exits off. See symbol CHK on 3 June Review Hi Howard, Thank you so much!

This is an insightful book that has rally doubled my knowledge of quantitative trading in one reading. And it's the sort of book that one wants to read many times as new ideas and questions form.
I like mr bandy's style a lot. His no-nonsense approach requires everything to be tested, which is right up my alley. No fluffy candlestick patterns or trend lines or anything that can't be rigorously tested. Anyone who has done a fair amount of coding in other platforms should have no trouble translating, but it does make the book somewhat specialized.
If you have an interest in swing trading systems that can be rigorously tested though, don't miss this book! I have each book published by Howard Bandy. This book, the Mean Reversion one, is the first that I've read in detail. I've worked through various aspects of each of the others. Howard Bandy is one of the real centers of knowledge on this topic and the topic of system development.
The books are gems. Prior to reading this book, I noted that one other reviewer's comments consisted of how this book is a "major contribution" to technical analysis. Having now read it, that reviewer's comments were no overstatement: It is most certainly a major and important contribution.
When used against the backdrop of Bandy's other publications, this is also a major contribution to the thinking dealing with system development. You can and will learn an enormous amount from this author. Thanks to the author for putting together a very valuable collection of books. Bandy carefully takes the reader through elements to consider to come up with trading systems which have low single digit levels of drawdown.
Not only does he explain the systems thoroughly, he gives the Amibroker code, which enables one to use the system in one's own trading. The only qualm I have with the book is that I wish the author would have added an equal amount of short systems. There are some of us who trade options, and it's just as easy to short as it is to go long.
Bandy's comment, below, as to why longs were the concentration of discussion. Not a field guide for mean reversion systems. Just got this book it looks like just what I wanted as I have been using AmiBroker for a long time and interested in trading systems and methods. The thing I am confused about is where do I find the code.
At the books end it says you can find down able code [ So where is the code or must I hand type it from the book? One person found this helpful 2 people found this helpful. This is a great book that was written by a truly knowledgeable computer scientist and skilled trader.
I've met the author, and he's a great guy and was generous with his knowledge. One person found this helpful.
