Cognitive Biases That Affect Traders

cognitive_psychology_irrational
Humans have weaknesses that hamper their trading capabilities. Many were developed in ancient times and were important for survival. I will enumerate the most important:
1) Loss Aversion: the strong tendency for people to prefer avoiding losses over acquiring gains

2) Sunk Cost Effect: The tendency to treat money that already has been committed or spent as more valuable than money that may be spent in the future

3) Disposition Effect: the tendency for people to lock in gains and ride losses

4) Outcome Bias: The tendency to judge a decision by its outcome rather then by the quality of the decision at the time it was made

5) Recency Bias: the tendency to weigh recent data or experience more than earlier data or experience

6) Anchoring: the tendency to rely too heavily, or anchor, on readily available information (more…)

8 Steps for Traders

1. Find Your Strength.  It is important that the trader determine what type of market, trending or consolidating, best suits their own personality and strength.  The best traders stay focused on one or the other and master it.

2. Know Your Market.  You should know your market when trading.  In other words, know the levels of support/resistance;  know how the instrument you trade moves with the general market; know who is likely to be on the other side and what they are thinking; and “the terrain of any market includes the “long-term charts”

3.  Prepare Your Order.  Know when to get into a trade and why and know when to get out of a trade and why.  Just like a secret agent who will “never enter a room without knowing how to get out of it in a hurry”

4.  Placing Your Order.  Once you have adequately prepared for a trade, it is then necessary to be ready to place the trade when the time is right.  Here “patience is the key…you must be able to wait for the market to tell you when the moment is right.  Wait for the market to generate the action; don’t force it”

5.  Sticking With Your Plan.  This is probably the hardest part about trading.  Once you enter the battlefield (enter a trade), the emotions of fear, ecstasy, greed, and sheer excitement can then take over and cause you to forget your well prepared plans for entry and exit.  You must enter a “Zen-like mental state” where you remain in control of your emotions.  Not doing so could spell disaster.

6. Identify When You Are Wrong.  “It is crucial to your survival to identify in advance whether your view might be wrong and to determine what price level, when broken, would be in support of the consensus view; therefore, you are building up your ability to defend the occasional probes against you”

7.  Holding On To Your Winning Positions.  Set a trailing stop when your trade is moving in your direction thereby locking in profits while allowing the trade to work toward its maximum potential.  “A trailing stop loss keeps you in the war, keeps you in tune with the war, and, most important, leaves you in full readiness to instantly strike again”

8.  Focus On Your Next Trade.  This is the most important step and is saved for last.  This step simply says to start anew with each new trade.  No matter if you won, lost, or broke even on the last trade, the next trade is a new one.  “You do indeed need to be starting every single trade fresh and alert without any baggage from the previous encounter”

Great links with Nicolas Darvas interviews

“Since he has to do trading from wherever he is dancing he ignores tips, financial stories and brokers’ letters, and has never been in a broker’s office. Basically, his approach is that of a chartist: he watches price and volume … When a stock makes a good advance on strong volume, he begins watching it, buys when he feels that informed buyers are getting in. For example, when he was playing in Calcutta, he noticed E. L. Bruce moving up in the stock tables. Suddenly, on 35,000 shares it moved from 16 to 50. He bought in at 51, though he knew nothing about the company, and ‘I didn’t care what they made.’ (They make hardwood flooring.) He sold out at 171 six weeks later.

Darvas places his buy orders for levels that he considers breakout points on the upside. At the same time, he places a stop-loss sell order just below his buy order, so that if the stock does not move straight up after he buys, he will be sold out and his loss cut. ‘I have no ego in the stock market,’ he says. ‘If I make a mistake I admit it immediately and get out fast.’ Darvas thinks his system is the height of conservatism … If he has a big profit in a stock, he puts the stop-loss order just below the level at which a sliding stock should meet support. He bought Universal Controls at 18, sold it at 83 on the way down after it had hit 102.

Darvas trained for the market just as methodically as he had studied his dancing, read some 200 books on the market and the great speculators, spent eight hours a day until saturated. Two of the books he rereads almost every week: Humphrey Neill’s Tape Reading and Market Tactics and G. M. Loeb’s The Battle for Investment Survival. He still spends about two hours a day on his stock tables.”

That line, “[He] buys when he feels that informed buyers are getting in,” made me chuckle. It should read “He buys when he suspects that uninformed fools are piling in.”

An Interview With Nicolas Darvas in 1974:

Don’t forget I too went through a period of learning from 1953 to 1958 where I lost a substantial amount of capital before I worked out what worked and then was lucky enough to time it in the 1958-1960 bull market.”

Richard Rhodes’ 18 Trading Rules

“Old Rules…but Very Good Rules”

  1. The first and most important rule is – in bull markets, one is supposed to be long. This may sound obvious, but how many of us have sold the first rally in every bull market, saying that the market has moved too far, too fast. I have before, and I suspect I’ll do it again at some point in the future. Thus, we’ve not enjoyed the profits that should have accrued to us for our initial bullish outlook, but have actually lost money while being short. In a bull market, one can only be long or on the sidelines. Remember, not having a position is a position.
  2. Buy that which is showing strength – sell that which is showing weakness. The public continues to buy when prices have fallen. The professional buys because prices have rallied. This difference may not sound logical, but buying strength works. The rule of survival is not to “buy low, sell high”, but to “buy higher and sell higher”. Furthermore, when comparing various stocks within a group, buy only the strongest and sell the weakest.
  3. When putting on a trade, enter it as if it has the potential to be the biggest trade of the year. Don’t enter a trade until it has been well thought out, a campaign has been devised for adding to the trade, and contingency plans set for exiting the trade.
  4. On minor corrections against the major trend, add to trades. In bull markets, add to the trade on minor corrections back into support levels. In bear markets, add on corrections into resistance. Use the 33-50% corrections level of the previous movement or the proper moving average as a first point in which to add.
  5. Be patient. If a trade is missed, wait for a correction to occur before putting the trade on.
  6. Be patient. Once a trade is put on, allow it time to develop and give it time to create the profits you expected.
  7. Be patient. The old adage that “you never go broke taking a profit” is maybe the most worthless piece of advice ever given. Taking small profits is the surest way to ultimate loss I can think of, for small profits are never allowed to develop into enormous profits. The real money in trading is made from the one, two or three large trades that develop each year. You must develop the ability to patiently stay with winning trades to allow them to develop into that sort of trade.
  8. Be patient. Once a trade is put on, give it time to work; give it time to insulate itself from random noise; give it time for others to see the merit of what you saw earlier than they.
  9. Be impatient. As always, small loses and quick losses are the best losses. It is not the loss of money that is important. Rather, it is the mental capital that is used up when you sit with a losing trade that is important.
  10. Never, ever under any condition, add to a losing trade, or “average” into a position. If you are buying, then each new buy price must be higher than the previous buy price. If you are selling, then each new selling price must be lower. This rule is to be adhered to without question.
  11. Do more of what is working for you, and less of what’s not. Each day, look at the various positions you are holding, and try to add to the trade that has the most profit while subtracting from that trade that is either unprofitable or is showing the smallest profit. This is the basis of the old adage, “let your profits run.”
  12. Don’t trade until the technicals and the fundamentals both agree. This rule makes pure technicians cringe. I don’t care! I will not trade until I am sure that the simple technical rules I follow, and my fundamental analysis, are running in tandem. Then I can act with authority, and with certainty, and patiently sit tight.
  13. When sharp losses in equity are experienced, take time off. Close all trades and stop trading for several days. The mind can play games with itself following sharp, quick losses. The urge “to get the money back” is extreme, and should not be given in to.
  14. When trading well, trade somewhat larger. We all experience those incredible periods of time when all of our trades are profitable. When that happens, trade aggressively and trade larger. We must make our proverbial “hay” when the sun does shine.
  15. When adding to a trade, add only 1/4 to 1/2 as much as currently held. That is, if you are holding 400 shares of a stock, at the next point at which to add, add no more than 100 or 200 shares. That moves the average price of your holdings less than half of the distance moved, thus allowing you to sit through 50% corrections without touching your average price.
  16. Think like a guerrilla warrior. We wish to fight on the side of the market that is winning, not wasting our time and capital on futile efforts to gain fame by buying the lows or selling the highs of some market movement. Our duty is to earn profits by fighting alongside the winning forces. If neither side is winning, then we don’t need to fight at all.
  17. Markets form their tops in violence; markets form their lows in quiet conditions.
  18. The final 10% of the time of a bull run will usually encompass 50% or more of the price movement. Thus, the first 50% of the price movement will take 90% of the time and will require the most backing and filling and will be far more difficult to trade than the last 50%.

There is no “genius” in these rules. They are common sense and nothing else, but as Voltaire said, “Common sense is uncommon.” Trading is a common-sense business. When we trade contrary to common sense, we will lose. Perhaps not always, but enormously and eventually. Trade simply. Avoid complex methodologies concerning obscure technical systems and trade according to the major trends only.

During and After the Trade

1. What’s your game plan if it goes against you and threatens your survival?

2. Will you be able to get out? Did you take that into account in your workout?

3. More typically, what will you do if it goes way against you and then meanders back to give you a breakeven? Or if it immediately goes for you or aginst you?

4. Would you be willing to take a ½% profit if you get it in the first 10 minutes?

5. Did you test whether taking small opportunistic profits turns a winning system into a bad one?

6. How will unexpected cardinal events affect you like the “regrettably,” or the pre-annnouncement of something you expected for the next open? And what happens if you’re trading an individual stock and the market goes up or down a few percent during the day, or what’s the impact of a related move in oil or interest rates?

7. Are you sure that you have to monitor the trade during the day? If you’re using stops, then you probably don’t have to but then your position size would have to be reduced so much that your chances of a reasonable profit taking account of vig are close to zero. If you’re using 10% of your capital on a trade, they you’ll have to monitor it for survival. But, but, but. Are you sure you won’t be called away by phone calls, or the others?

8. Are you at equilibrium in your personal life? You’re not as talented as Tiger Woods, and you probably won’t be able to handle distressed calls for money or leaks on the home front. Are you sure that if you’re losing you won’t get hit on the head with a 7-iron, or berated until you have to give up at the worst possible time?

9. After the trade did you learn anything from the trade?

10. Are you organized sufficiently to have a record of all your trades for your accounting and learning?

11. Should you modify your existing systems based on it?

12. How does recency and frequency and value affect your future?

13. Did you fit your after activities to your mojo?

14. If you made a good profit, did you take some capital out of the fray for a rainy day?

15. Have you learned to say “fair” whenevever anyone asks you how you’re doing and are you sure that you don’t spend a fortune after a good trade, and dissipate your profits with non-economic activities?

16. Is there a better use for your time than monitoring the ticks or the market every minute of the day if you do, and if you don’t, do those who do so and have much faster and better equipment than you have an insurmountable advantage against you?

Money Management

The overwhelming reason that traders win or lose is not because of their entry method, but because of their money management skills.

By “money management” it simply mean keeping losses and drawdowns to an absolute minimum while making the most of opportunities for profit.Good Trader must keep his losses to a minimum to ensure his survival. If you keep your losses to a minimum on every trade, you will have 80 percent of the battle won.

Important‑if the market starts to move parabolically or has a rangeexpansion move, take profits on the entire position. This is very likely climax!
‘When the ducks quack, feed them.” In other words, when everybody wants something, that’s probably the perfect spot to sell it to them. The price has already been bid way up. Emotions drive the markets to extremes, and these extremes are the ideal spot to exit our trades.
