Behavioral biases favor trend following

Commodity Trading Advisors (CTA) that utilize trend following through managed futures accounts have long known that there is no Holy Grail in investing.

When following trends, they know that anything can happen, so they have completely abandoned strategies involving fundamental analysis or buy-and-hold fallacies. Many successful trend followers and CTAs have developed trend following systems based on multiple time frames with the objective to harness the trend that herding generates in the market. In order to do that, their primary focus lies in managing risk so that the return would somehow take care of itself. Whenever they engage themselves in a trade, the potential loss is always known upfront.

In perhaps no other industry, subjective misjudgments become so blatantly obvious as in the trading business. Trend following tries to circumvent this. Behavioral finance has documented some of the investor biases explaining the rationale for trend following:

  • Anchoring bias: Tendency to rely too heavily on one piece of information, specifically the recent price history to estimate “fair-value”.
  • Bandwagon effect and feedback trading: Tendency for traders to act as a group and jump on the bandwagon of a rising price trend (herding).
  • Confirmation bias: People tend to look for information supporting their beliefs and consider recent price moves to be representative of future prices. This leads investors to over-allocate funds to markets having already risen and under-allocate to fallen markets. This behavior favors trend continuation.
  • Overreaction: Market participants overreact to new information, creating larger- than-warranted effects on market price and stronger trends.

The trend following industry prefers to analyze trends on a meta-level according to the Dow Theory: Higher highs and higher lows for an uptrend, or lower lows and lower highs for a downtrend.

Practitioners understand that the crowd is always collectively smarter and therefore do not bother to predict or outsmart the market with discretionary analytical methods. Instead, their goal is to participate in the crowd’s wisdom and follow the path as it is given to them without judgment.

Traders’ delusion with random patterns

In his book How We Decide, Jonah Lehrer wrote about a simple experiment conducted among students at Yale University. It reminded me a lot of the senseless undertakings that traders do to seek logic in random price action:

Look, for example, at this elegant little experiment. A rat was put in a T-shaped maze with a few morsels of food placed on either the far right or the far left side of the enclosure. The placement of the food was random, but the dice were rigged: over the long run, the food was placed on the left side 60 percent of the time. How did the rat respond? It quickly realized that the left side was more rewarding. As a result, it always went to the left of the maze, which resulted in a 60 percent success rate. The rat didn’t strive for perfection. It didn’t search for a unified theory of the T-shaped maze. It just accepted the inherent uncertainty of the reward and learned to settle for the option that usually gave the best outcome.

The experiment was repeated with Yale undergraduates. Unlike the rat, the students, with their elaborate networks of dopamine neurons, stubbornly searched for the elusive pattern that determined the placement of the reward. They made predictions and then tried to learn from their prediction errors. The problem was that there was nothing to predict; the apparent randomness was real. Because the students refused to settle for a 60 percent success rate, they ended up with a 52 percent success rate. Although most of the students were convinced that they were making progress toward identifying the underlying algorithm, they were, in actuality, outsmarted by a rat.

The hostile opponent never ceases

Have you experienced repeated hostility from someone, without a chance to change the situation? This is probably what every trader is confronted with every day. I am not referring to a distinct enemy figure per se, rather a metaphor for everyone whose opinions and actions oppose your interests. Trading is challenging (at the very least, it is emotionally exhausting). I don’t attempt to sweet-talk it.

If you are long, you condemn the bears for selling off. Once you switch sides, you condemn the bulls for recovering. There is little you can do about it. As a trend follower, I’m in a position basically throughout the year, which is why I have to deal with adverse movements frequently. The only solution I have found is to look at the big picture and trade trends that sustain itself over multiple days while managing my stops rigorously.

Although it demands a lot of attention, trend following can be done in any market condition. It is only a matter of time frame and frequency of adjustments whether you prosper from trends or not. If I’m wrong, I will be stopped out. If I am right, I still have to manage risk because no trend lasts eternally.

Yesterday was the perfect example of adversity. A new rally was gaining traction the previous day, after the price broke a multi-day downtrend (see 4H chart below). I was in a long position since then and pleased that the market closed near the highs of the session. On the following day I first witnessed some stability, until a news item must have disrupted the harmony. We dropped nearly 30 points off the pre-market highs. I condemned this.

Why is the market never sticking to its direction? Why must it be so challenging to trade? At the same time, I was aware that the trend had already shifted so drastically that going short was out of any sensible options. So I hang on. I waited. Maybe the market simply got ahead of itself in the first place.

The S&P 500 started to recover eventually and we are now back to the old highs as if nothing had happened. A lot happened emotionally, though. It was a battle within myself. We may scold imaginary bullish or bearish participants, but we are actually our worst enemies. The equity curve is the direct result of our own trading decisions. When entering a trade, one is too consumed with the very moment, so that the emotional impacts of subsequent adversities are neglected. A trend follower may not expect markets to explode higher every minute, but neither does he like a vicious sell-off.

At least we formed a higher low which means that the uptrend remains intact, and I can adjust my stop to that area now. In the broader context, the bear’s attempt at pushing prices lower resulted in just a minor dip.

The cat and mouse game of newbie traders

An ubiquitous urge, particularly among beginners, is to predict how markets are going to evolve in a given course of time. In fact, having predictions subconsciously leads to trading them instead of actual market conditions. They become so inextricably enmeshed with a trader’s bias that objective judgments are not possible anymore.

If I were to review your trades of a given day, I would probably find numerous trades coupled with little proceeds you got from them. Such activity points out that you have been trading an expectation which failed to materialize. Second thoughts forced you to close a position before the market turned against you big time.

While the market wiggles and you take one loss after another, the experienced trend follower has been staying in his position during the whole time. No action was taken at all, but yet the trend follower ends up with a more advantageous position than the one who is being assertive. Why is that so? That experienced trader listened to the market and is thus convinced of his strategy, his bias, his position, his stop, even himself. Be more convinced of yourself. To avoid fearful closing of trades, you have to know why you are opening a trade in the first place, based on objective observation of price action. What is your rationale for going long or short? Every single trade of yours should be planned out with great care.

The majority of traders who begin with futures trading, choose to scalp out of fear and are so focused on the tiny wiggles that everything looks like an opportunity. We witness this behavior in various trading forums and online chats. What’s happening is subjective trading out of gut feel and fooling oneself with regards to progress made. This getting in-and-out every minute never seemed to me a paradigm for success in the long run. Let me attempt to redirect you to the right path if you feel that you still belong to this majority of self-deceiving traders.

The market is a master in tricking the average person. Since one cannot predict markets – or turnarounds for that matter – another plausible explanation for hyperactivity (besides prediction) is that a trader tries to catch up with the market. He missed out on the easy move down and is now at a disadvantage. Consequently, the only solution that he can think of is to buy into every spike, hoping to participate in a big rally. While the anticipated move fails to materialize, he is taking one pounding after another.

This show turns into real comedy after the market has actually turned around. Now the trader is feeling left out all over again. He subconsciously reverses his habit, and keeps shorting on the way higher. He is playing cat and mouse with the market all day long, only to lick his wounds in the end.

What is a Trend?

We need to acknowledge that markets do not move like elevators, but like waves within a current. Uptrends are always interrupted by frequent reactions, whereas downtrends will witness just as many rallies. What we focus on, is the overall current in the shape of trends because this tells us the path of least resistance.

According to the Dow Theory, an uptrend is defined by a sequence of higher highs and higher lows. A downtrend is a sequence of lower lows and lower highs. Look at the ES in the 1H or 4H time frame, for example, and you will surely get a clear picture of trends that you can take advantage of.

If a market is still showing a series of lower lows and lower highs, one simply does not go long in this environment. Buying is a much more challenging proposition because a long position will most likely fail sooner or later. This is due to the strong underlying market forces that are able to break support areas sooner or later.

At some point you may be lucky enough to have caught the bottom, but is it worth it? Let’s be realistic. Even if you did catch the perfect bottom, you have most likely exited prematurely out of fear of another sell-off anyway. So much energy is expended on catching turnarounds, resulting in so little proceeds while you could have it much easier.

Trends take time to shift from bearish to bullish. You will notice a shift soon enough once sellers stop selling where they are supposed to and buyers are cracking a significant resistance area. This all becomes visible in the aforementioned time frames.

Alternatively, regard price action from a psychological standpoint: Imagine yourself in the position of the buyer, then in the position of a seller. What would you be thinking in each case? Would you be contented with what’s happening in the market? What would you like to see to stick with your bias? It is a chess game. This thought process is very powerful because it gives you a more objective view on the market and makes you reflect on the price action.

Listen to the Market

Beginners focus too much on the random moves intraday, than the actual trend in the broader perspective. Trade those, and you will witness far greater success. It is evident that a trader gets confused every single trading day anew. Randomness has no logic, so do not seek logic in randomness. Random profits also create the delusion of progress in your trading. You get random rewards playing craps, too. But that does not mean that you know what the dice are going to do at the next roll.

To escape randomness, you must feel comfortable with holding your position over night, even several nights. It is a common misconception communicated among beginners that you need to close your trade within the same day. Trends last more than a single day. They last multiple days to weeks, sometimes months. Why? Because public sentiment does not shift from one moment to the next but takes a long time.

To trade such multi-day trends, you will need to figure out which support and resistance area is of real importance, and observe the price closely at those areas. They will stand out visibly as a trend unfolds and your eye will be trained to spot them by the time. A break of such zone is a potential entry for a new trade. By trading longer term time frames, you will not trade randomness, but trends that sustain themselves over multiple days. A welcome side-effect is that your broker commissions sink drastically.

Only take action if you observe clear evidence for a reversal. Otherwise you are better off doing nothing and letting the stop-loss order work for you. A stopout should happen where the original reason for your entry is no longer given due to objective observation of price action – not your gut feel.

The risk of using multiple time frames

You may find it discouraging, or even boring, if a market has not been offering a good setup for a longer while. Some books actually talk about how using multiple time frames can improve your trading and help with spotting potential setups. Instead of encouraging it, I would rather take this advice with care.

If you look at more than one time frame just because you cannot find a potential entry, you are basically forcing yourself into trades. In this case, using multiple time frames will backfire. They should solely be used to get a better view of the overall market situation. The actual trades, however, need to be executed based on the time frame you have backtested your strategy with.

I backtested my current trend following strategy back to mid 2009 with a one hour chart and it has never failed fundamentally at yielding a consistent return. A trader’s objective is not about being involved in the market at whatever cost, but about preserving what has been captured and refraining from trades when there is no opportunity presented. In case the market has nothing to offer, so be it. I don’t have a particular goal with regards to trading but to make right decisions. Even a loss is only worth it, if it happened despite having made the right decisions. The rest will take care of itself. It basically boils down to pure statistics, or your “edge”.

You certainly can trade shorter time frames in the minutes or ticks. I am personally of the impression that the shorter the time frame, the more randomness is involved in price action. So I rather stick to my mantra of objectiveness and trade those trends that are really there to stay and not fade within a few minutes time. I wouldn’t be able to manage that. I would get severely frustrated. Therefore, I trade best with the one hour chart. Missing out on the smaller swings, and giving back portions of unrealized profits during counter-moves is the consequence of my approach. In trading, you sadly can’t have the cake and eat it too.

Overleveraging distorts your judgment

How can a trader make sure to decide rationally and improve his or her performance? Right now, I am comfortable with 1 contract and do not want to mess up with revenge trading, fearful trading, you name it. I find it extremely important to trade the size that I am comfortable with. This will ultimately decide whether you will be profitable as a trader or not.

Even if people claim that they are fine with futures, deep inside they are actually not. Why would traders place tight stops and scalp in the first place? It’s because they cannot handle its size and feel the heat as soon as a trade goes against them a few hundred dollars. Capabilities of objective judgment are lost in such financially threatening situations.

I originally tested my strategy with CFDs that are unfortunately not available in the US. CFDs work just like futures with all their benefits (no day trading limits, leverage, scalability, around the clock trading) but at a fraction of their size, namely 1/50 for the S&P 500. It made a big difference emotionally and trading 5 CFDs in the beginning was a smooth ride because I couldn’t care less if a trade failed. This comfort is precisely what a trader needs to feel (both professional and beginner).

“Sell to the sleeping point.” Trading will be significantly easier the conservative way and performance improves because you stop doing those stupid mistakes that you would do with a leverage that blows your account anytime a trade fails.

The market will be here tomorrow, and the ES will hopefully exist throughout my entire lifetime. Hence, there is no rush to get greedy because the market will be offering enough opportunities going forward.

Charlie Wright on prediction

Charlie Wright, Chairman of Fall River Capital, LLC:

It took me a long time to figure out that no one really understands why the market does what it does or where it’s going. It’s a delusion to think that you or any one else can know where the market is going. I have sat through hundreds of hours of seminars in which the presenter made it seem as if he or she had some secret method of divining where the markets were going. Either they were deluded or they were putting us on.

Most Elliot Wave practitioners, cycle experts, or Fibonacci time traders will try to predict when the market will move, presumably in the direction they have also predicted. I personally have not been able to figure out how to know when the market is going to move. And you know what? When I tried to predict, I was usually wrong, and I invariably missed the big move I was anticipating, because it wasn’t time.

It was when I finally concluded that I would never be able to predict when the market will move that I started to be more successful in my trading. My frustration level declined dramatically, and I was at peace knowing that it was OK not to be able to predict or understand the markets.

You need a trading plan

Trading is a business like any other. Treat it accordingly. It’s about the evaluation of risk for a potential trade. Everyone who has been involved in the financial market for a while will know to appreciate a trading plan. Market participants who have been hurt with losses regret not having had one from the first moment on. After all, it is more exciting to jump into the first trade and get the drill immediately.

Imagine you were about to buy property. Wouldn’t you balance the pros and cons of the location, the buying price, or your monthly annuity? You certainly will not buy the first property that comes across you. Unfortunately this is precisely how beginners approach trading. The hurdles of opening a trading account and depositing some cash are far lower than, say, registering your own business. Henceforth, trading is not taken as seriously.

When composing your trading plan, you have to understand most of all yourself. Why do you want to trade? What are the specific goals you are trying to achieve with trading? How much time during the day can you dedicate to it? Can you handle a loss of $50, $1,000, or $5,000 per trade? How would such a loss affect you? Do you prefer to harness large trends, or quick trades throughout the day?

The next step is to find the right market and the right time frame. For example, I have chosen the ES for myself because I want to focus on one instrument and trade it well. My primary time frame is the 1 hour chart.

Going further, you need to know your specific trading strategy. Create one that is as objective as possible because such will stand a higher chance to last throughout various market conditions. I have abandoned all indicators and focus merely on the price. This is what every market participant is seeing. Define where your stop-loss would be at and what the potential loss is if it gets hit. I want to make sure to quit the trade if the original reason for entry is no longer given. I take visible peaks or troughs to put the stop-loss at. With the help of the 1 hour time frame, I am able to detect significant support and resistance areas which help me to find an entry. Everyone will notice if a new high or low is taken out. Do not miss to test your tactics on paper before risking real money.

Prepare a trading journal once you have collected some experience and want to get to know yourself better. Write down your emotions, your reasoning for each action made, and a lessons learned for upcoming trades. It seriously helps at becoming more objective in your trading decisions. You engage yourself with the decisions made and will be more alert of making mistakes in future.
