Trend Following: A complete guide into TurtleTrading and their legacy

Michael Covel has dedicated three books on the legendary turtle traders group and their so-called “trend following” trading strategy. This article is my personal view of his work, the lessons I personally took from them, as well as my opinion on them.

This article should not be viewed as a replacement of the book but rather as an introduction or as a side guide. Everybody learns and takes away different things from a book from another.

The Story Behind the Legend

It all started when Richard Dennis and William Eckhardt got into a debate on whether or not trading could be taught. To settle this debate, Richard Dennis posted an advertisement in the Wall Street Journal, Barron’s, and the International Herald Tribune, in 1983, in order to find his students. This had, as a result, the formation of the first turtle traders group that was compiled of 21 men and 2 women.

One turtle trader visited Singapore at one point in time and saw a turtle farm. When returned, the name “turtle traders” was suggested to the group as a metaphor. Richard Dennis was raising a trader out of each one of the traders, as the farmer was raising turtles on the farm.

After a 2-week intensive theoretical training, each turtle got an account funded by his own money, for them to trade individually. When the experiment ended, they had produced a $175'000'000 profit.

Here it is worth mentioning that from the whole 23 initial turtle trader group, only 1 person trades to this day and has his own trading company. His name is Jerry Parker.

In 1984, was the second way of turtle traders, and in 1985 a third.

My Personal Intakes from Michael W. Covel’s Books

Trader Psychology

  1. Do not afraid to follow your trading system when your money management is set.
  2. Good trading and intelligence are not correlated. Emotional intelligence, on the other side, is way more important.
  3. Your long-term progress is your only performance metric.
  4. Do not revenge trade, meaning do not try to make up for lost positions. Move on.
  5. Follow what the market gives and do not oppose personal opinion on the market.
  6. Self-discipline is the most important characteristic of a trader’s personality.

Money Management

  1. No trader wins every time. When he or she wins though wins big, and when loses, he or she loses small.
  2. Do not risk more than 2% of your account in any trade.
  3. The exit is more important than the entry.
  4. Cut your 2% risked amount, mentioned-above, by 20% each time you achieve a 10% drawdown on your account.
  5. When we enter into multiple positions with correlated assets, we introduce our portfolio to more risk. We could either lower our 2% risked amount to every position or use uncorrelated assets.
  6. Use either the lower level of a 10-day DOnchain channel as an exit or a double-daily-volatility amount.

Trading Strategy

  1. Follow your strategy, even if you lose five trades in a row. This will also remove any emotion from your trade.
  2. A trader needs a trend to make money, and thus the name “trade following.” Do not trade a sideways market.
  3. Buy when the price moves above the high of the two previous weeks, and sell when the price moves below the low of the two previous weeks.
  4. Plan your next day in advance.
  5. A trader needs to know the volatility of the assets he or she follows. (use the Average True Rande (ATR) indicator for a 15-day average.)
  6. Add to your winners when the price makes a move equal to the amount of the daily volatility level. This will be used as a compound to your account.


  1. Traders do not forecast or predict the price. If you ask a trend follower for a forecast, they should answer “I do not know.” They simply follow the direction of the market according to their strategy.
  2. Do not listen to the news, stock tips, reports, etc. Nobody can predict the future and thus the markets. Traders need to simply follow the price.
  3. Every piece of information concerning an asset is already calculated inside its price. The markets then are efficient.
  4. Black swan events can and will happen from time to time.
  5. “Markets in motion tend to stay in motion.”
  6. Nobody can pick the bottom or the top of a move so do not worry about it.
  7. Fundamentals are useless to a trader. True price movers are always unknown.
  8. There is no reward without risk.
  9. There is no such thing as the price is too high or too low in an asset.

The Trend Following Strategy


Stop Losses: Take whichever hits first.

(System 2) Stop Loss 2: We exit a bullish position when the price breaks the 10-day lower lever of a Donchian channel, and we exit a bearish position when the price hits the 10-day upper level of a Donchian channel.

Adding to your winners:

Execution Day

A trader needs to experiment with different day lengths and find what suits him or her the best. A good starting point is the ones mentioned above.

Example 1: Berkshire Hathaway Inc — Bullish Move

In the example below, you can see from left to right, a possible entry when the first green candle broke the green upper line of the indicator. We followed the red line as a stop loss until the price touch the red line and closed our position. The yellow arrows and line shows our gain.

Example 2: USD/EUR— Bearish Move

Example 3: Basic Fit — Sideways Move

Step 2. Chose the asset you want to trade and check if it is already trending. If on a bullish trend, then you look to enter into a bullish position. If bearish, you look to enter into a bearish position. Do not open a position on an asset that makes a sideways move.

Step 3. Add the Average True Range (15) indicator to your chart and check the daily ATR range. That’s the daily volatility (1N) amount of this instrument. If the price makes a 1N in your favor, you add to your position. If the price makes a 2N move against you, you close your position.

Step 3. Bullish: You add a Donchian channel indicator with a 20-day upper level and a 10-day lower level. You enter a position when the price hits the upper level, and you exit the position when the price hits the lower level.

Step 3. Bearish: You add a Donchian channel indicator with a 10-day upper level and a 20-day lower level. You enter a position when the price hits the lower level, and you exit the position when the price hits the upper level.
