Almost all backtests are to a certain degree curve-fitted — mostly unconsciously. The missing element is out of sample testing :.

An underrated part of trading is out of sample testing. Out-of-sample backtesting is when you divide your backtest into two parts: in sample vs. out of sample. The in-sample test is where you make the rules, signals, and parameters.

The out-of-sample is where you test your rules and signals on unknown data. The best out of sample backtest is an incubation. In this article, we explain what out of sample trading tests are and look into why this is important and how you should test out-of-sample in your backtesting. In sample vs.

out of sample means dividing your historical data into two parts: one part where you make the rules and parameters in sample , and one part where you test the in sample rules on unknown data out of sample.

Finally, before putting real money to the test, you test the trading strategy live in a demo account. At the end of the article, we test a short strategy by diving the backtest into two parts: in-sample and out-of-sample.

In order to succeed as a trader, you need to spend a lot of time testing ideas. We have written about this before:. Because most strategies tend to wither away as time goes by, due to a number of reasons.

One reason is curve-fitting in your backtests, and another reason is that markets change. This website is all about quantified trading, and backtesting is an essential part of forming trading strategies.

Backtesting is when you test your ideas on a sample of data to see how they performed historically. An in-sample test is simply the testing you do on your available data. Many traders like to split their dataset into two parts: one part to test in-sample and one part to test out-of-sample.

You compare the in-sample data vs the out-of-sample data:. When you have tested a trading idea and formed a conclusion you need to test your trading strategy on unknown data.

A practical way of testing is by splitting the dataset into two parts, for example, the in-sample test from until , and then out of sample from until Validation is when you confirm your trading idea or hypothesis via an out-of-sample test. Did the in sample predict the out-of-sample results well?

If not, you should not go live with the strategy or you should wait or test more. You get your results in the blink of an eye, but you miss the details.

We believe the best way to perform an out-of-sample test is to use a live demo account. We like to call this the incubation period. You observe the strategy and see how it performs out of sample.

Furthermore, you might discover some small details you never thought of when you did the testing. The main advantage with this method is time: a backtest is done in seconds and minutes, but via a demo account you discover the strategy in real life.

A backtest done in minutes is worth a lot less than incubation, in our opinion. Not in my book. What about adding a new rule, say a moving average cross? Still probably not enough? What if I remove a rule and add profit target?

There is no clear change to strategy when it is OK to use the data again. It is up to each individual to decide and that means we are likely to fool ourselves and say that small change is enough. Also we have knowledge about our test period.

I know from experience that mean reversion trading diid well from to If I use to as my OOS sample data for a mean reversion test, is that cheating? When we run our strategy on the OOS data, how do we know that it passed the OOS test?

First, the strategy will probably not perform as well because it was developed on the current market conditions and now it is being tested on different ones.

What if the CAGR only dropped a little? That sounds like a pass. But what if that is the worst CAGR if you ran all your original variations on the OOS data?

How about a goal of beating a simple strategy? Buy the SPY when it crosses above its day moving average and sell when it closes below it. I use this idea and another which I will explain in the next post.

Now this is where I have my biggest issue with how OOS testing is normally done. For example, we have a strategy with 1, variations. We go through some method to pick one to test on the OOS data.

See this post on how I would pick The One. Now we run The One on the OOS data and make our decision. Here is where I have my problem. What if I got unlucky and picked a variation that did poorly during this timeframe but many of my other choices did well.

My strategy concept held up but just not the one I picked. That is wrong because what we want to know is did our strategy concept hold up in OOS. Imagine the reverse scenario. Your strategy concept sucks and it behaves as well as choosing random entry and exit times.

Now you are off trading a strategy that is as good as random. In the next post , I will show results of doing an IS and OOS testing on a mean reversion strategy and how picking only one variation can be dangerous.

Then I will show how using a set of variations is a much better way to help determine if your strategy did well in OOS testing. The post will also show how one can come to different conclusions depending on how the IS and OOS ranges are chosen.

While waiting for the next post , you can read Optimization Mean Reversion which covers some of what I will next. Hi there.. thx for your article, I have to agree with everything what was said. Save my name, email, and website in this browser for the next time I comment. There is one more related issue in oos testing, out-of-sample data snooping.

Hi Cesar, thanks for an excellent post and I think you are spot on. There are plenty of issues to consider.

I like your idea of using a range of parameter values corresponding to high performance areas of an IS optimisation, for OOS testing, instead of picking the best set,. Otherwise you will not be able to use it later.

Now when we have loaded all data it is time to test our idea. In this demonstration we will be investigating what happens if you buy when the RSI2-indicator crosses over 50 and sell after 5 days.

This looks quite alright, but we want something better, so we try to tweak it a little bit by running an optimization and see what values work best.

We find that it was better to wait a little longer before selling, so we will not sell after 10 days instead of 5. This is starting to look quite alright. However, we want better performance, so we will try to add a filter!

After having tried many different indicators and setups, we find that applying the RSI2 indicator to the day prior to the signal, and requiring it to be over 15, works well. At this stage, we are satisfied with the performance, and decide to leave it here.

The strategy is ready for the out of sample verification. This was why we saved some of the data as out of sample. Below you can see how our strategy performed on the out of sample data.

As you can see, it does not fail miserably but makes no new equity highs in the out of sample data. If the market has not changed between our in sample and out of sample periods, the only thing we did was to curve fit our strategy to market noise.

It is clear that this strategy failed, which might not be that fun to realize. Especially not if you have put hours of hard work into developing it.

Nevertheless, it is much better than losing money trading it live! The main premise of out of sample testing is that true market behavior will be consistent throughout both data sets, while random market noise will not. Therefore, an edge fit to random market noise will not work in the out of sample, while the opposite will be true for edges based on true market behavior.

However, no method is idiot proof and so applies to out of sample testing. A curve fit edge could very well pass out of nothing but luck! Even if in sample and out of sample testing can be a great tool to be able to discern curve fit edges from true ones, it can be misused.

The most common thing that many do, and that should be avoided, is that they convert out of sample data to in sample data without realizing it. What often happens, is that traders validate their idea on out of sample data, only to find that it has failed.

Upon that realization, they return to the in sample data, tweak their strategy, and test it again on the out of sample data. Effectively, what they have done is to convert their out of sample data to in sample data.

Out of sample data needs to be unseen not to lose its value! Another important point to keep in mind, is that every trader who performs many backtests , will soon memorize what the market has done at certain times.

And I can tell you that I treat my talent VERY well and they are very happy. I also pay them at a higher rate than what colleagues do - that's just me.

So if I was interviewing you and you made this assumption and declined to write the requested sample, you'd be passing up on a quality client.

Jul 17, AM by Evelin M. I'm here because I experience free sample work as well.. and I would like to know how I can get my point across fermly and hopefully to any higher authority, because there are so many things that upwork does great for clients, but not good at all for freelancers.

Why is it so easy to create a client account, no real verifications no tests, no "scam spotting" system in place for all the dodgy clients, because there are soooo many. The comunitiy is always saying, we are working on it, although nothing significant changed, only in the clients favour again, like the connects.

I guess nothing will change still the clients should be so fermly worned about the rules and how to treat freelancers so that they can't post any jobs until it;s clear Also, upwork dumpes so much of these on the freelancer that is not fair, like you spot the scamer, you be careful with spotting scam jobs, you investigate clients, and so on, it is not efficient time spent.

If I spend all my time delivering my service, I make more money there for upwork makes more money, if I'm working as a part time detective on upwork, how is that efficient?!

Instead of upwork being MORE strict with scam clients May 6, AM by Tim B. I think your response is definitely a good one, coming from one who asked a couple of writers for a new free sample without realizing that it was against TOS.

Assuming at first that the client simply isn't aware of this is absolutely the first step. I loved it and was thankful that one of the first 2 candidates followed your proposed solution, and I ended up making it right - getting the requested samples from both of them and then setting up quick contracts to pay them.

In the end I hired 2 other individuals, but I now know how to handle this without violating TOS. I can see why this condition is put in place to protect the talent from unscrupulous clients that wish to parse out their work into free pieces. I will add that there is a valid reason to ask writers for fresh samples.

Seeing existing portfolio work is a place to start, but there are unscrupulous writers out there who will have poorly written content professionally edited and then present this as their own work.

A brand new sample to specification is a necessary part of my interview process, to ensure that they can follow directions and can provide quality written content without the benefit of a professional rewrite. I don't mind doing some editing, but I've known colleagues who get unusable content back that must be completely rewritten.

Apr 4, PM Edited Apr 4, PM by Arjay M. I usually receive a wide number of clients who ask for free work. I told him that this is definitely against the terms of Upwork and of course against my protocol. Apr 4, PM by Tiffany S. Jan 13, AM by Ali K.

Nov 11, PM by Chaitanya B. Nov 11, PM by Jo-An B. Thanks a lot for linking me to the correct answer. Surely he has asked for free samples from others he is interviewing as he told me "The sooner you provide the sample, the better".

Hopefully they deny free work too. Thank you for your help 🙂. Jul 17, AM by Melanie H. Did you report the client? If this was discussed in your messages here you can still report it.

If it was in the job listing you can definitely report it. Jun 21, AM by Yumna Q. It is important to clarify the difference between free work and sample work. While free work implies completing a task without any compensation, sample work allows freelancers to demonstrate their skills and capabilities to clients.

As a freelancer, it is within your rights to ask clients if they are willing to pay for a test or sample work. If a client consistently refuses to compensate for your time and effort, it may indicate a lack of seriousness or a disregard for Upwork's rules.

In such cases, it is advisable to report the client if you suspect any fraudulent activity. However, it's essential to understand the complexity and importance of a client's budget. As freelancers, we should strive to demonstrate our abilities and professionalism without compromising our value.

If you can showcase your skills through a showreel or previous work, that can be an effective alternative to providing unpaid samples.

Remember, gaining a client's trust often comes from showcasing your expertise and understanding their needs. It is crucial for both freelancers and clients to respect Upwork's policies regarding free work, and to maintain open and transparent communication throughout the hiring process.

In order to avoid typing Code:. You just put this inside a loop: Code:. Clyde Schechter It worked all fine for the ordinary logit model. Now a somewhat harder question: is it possible to test the out-of-sample accuracy for the conditional logit model?

For this, I think I cannot use the conditional sample, since it only consists of 40 matched pairs, instead of the true sample of ~ firms of which ~40 targets.

This, self-evidently leads to extremely biased results. However, using this method, the other ~ firms would not have predicted probabilities. Do you maybe have any idea on how to assess the out-of-sample prediction accuracy for a conditional logit model? A conditional logit model doesn't have predicted probabilities, so you can't port them anywhere.

That's why your -predict- statement has to use the option -pc it is the probability that each observation in the group will have a positive outcome conditional on there being one and only one positive outcome in the group. In order to apply this model to the out of sample data, you would need to form matching-groups like those in your -clogit- data, and then do the out-of-sample prediction.

But if the "out-of-sample" data consists, as I think you are saying, of the observations for which no match could be found, then this approach is not possible. Mohamed Elsayed. Dear Clyde Schechter Many thanks for the valuable information you provide in this post and generally in the forum.

I have a similar question, please. I was reading a paper in which author was using two models Base Model and Complete Model to predict bankruptcy in one and two years before the bankruptcy using logit model. To determine which model is better, in one of the tests, the author draws a figure shows the "Prediction Success Rates" I uploaded a pic showing the figure.

The author indicates that the Figure reports the sum of Type I and Type II errors from the base and complete models.

The figure shows the sum of Type I errors classifying a bankrupt firm as healthy and Type II errors classifying a healthy firm as bankrupt according to the predicted values computed from each model. In case if the uploading pic of the figure fails, under the figure, the author provides this definition of what he did to plot that figure: "This figure plots the incidence of Type I errors classifying a bankrupt firm as healthy and Type II errors classifying a healthy firm as bankrupt according to model scores.

Model bankruptcy probabilities are ranked from lowest to highest. For a given percentile, we report the frequency of Type I and Type II errors. For example, at the 50th percentile, we consider the incidence of Type I and Type II errors if all observations with a model bankruptcy probability above the 50th percentile are classified as bankrupt and all others are classified as healthy.

The horizontal axis presents the cutoff point while the vertical axis presents the sum of Type I and Type II errors. Your help will be much appreciated. Thanks in advance, Mohamed. Follow up Clyde Schechter. For your kindly interest. Attached Files.

Hi Clyde, Many thanks for advising me on this. In terms of data, I should duplicate the figure I showed in my previous post using any data. But, let me explain the sample, the variable and model I should use.

The sample contains a number of firms that go bankrupt and healthy firms during this period, so it's panel or pooled dataset. Base Model is nested in the Complete Model. I already run the multi-period logit and get the coefficients by using the code " logit y x1 x2 x3 i. In the picture above, you can see how I have set up Tradestation.
