The real-life story of him is really an inspiring one. His principle is anyone could be taught to trade the futures markets. The turtle trading strategy mainly works on future trading.
Turtle Trading System FAQ
This is an old system. Turtles traded 100% mechanical using the specific system. Here the number of losers is more than the winners. But it has been seen that the winners are much bigger in terms of profit than the losers. Hence, this system still works very well if a trader can stick to the system.
The Turtle strategy was developed by Richard Dennis. The turtle experiment was based on the principle “anyone could be taught to trade”. It is a complete mechanical system that has specific entry and exit rules. The rule of buy entry is to buy a 20-day breakout. Similarly the rule for sell is to sell a 20-day breakdown. After the introduction of the turtle experiment, Dennis was considered as the most successful traders of that time.
The Turtle System was first introduced by Richard Dennis, a commodity trader. He introduced the system in 1983. Dennis was accompanied by William Eckhardt.
How The Turtle Trading System Was Introduced?
Richard arranged a Turtle Program by placing an ad in The Wall Street Journal. Among thousands of candidates, only 14 traders would make it through the first program of Turtle Techniques. Though Dennis had not released the exact criteria of the particular strategy, still traders use it widely in trading the live markets.
The Trading Rules
The specific technique is based on buying a future contract on a 20-day high(breakout) and selling on a 20-day low. The fundamental techniques guide the implementation of a trend-following strategy. It implies the reason for buying future breaking out to the upside of trading ranges and sell short downside breakout. It indicates an entry signal buying new four-week highs.
Position sizing includes a formula. Here the concept “N” represents the underlying volatility of a particular market. Simply N=20 days EMA (Exponential Moving Average) of the ATR (Average True Range). Therefore, N indicates the average price range that a particular market experiences in a single day. We can calculate the daily true range by maximum (H-L, H-PDC, PDC-L). Here PDC is the previous day close. Here we can always place the initial stop loss at 2N. (2xN) or 2% of the entire account equity.
Entering the position is the most significant point in trading. Turtle uses a simple entry strategy. Short term based on 20-day breakout and Long-term based 55-day breakout. The thumb rule is that if the first 20-day breakout stops out, don’t take the next 20-day breakout. Rather now wait for the long term entry, i.e, the 55-day breakout.
Turtles were able to find the following answers:
- How much is the volatility of the market
- What is the system orientation
- How much is the risk
- What is the state of the market?
In this strategy, the total winning amount is higher than losing because this system always adds to the position on the winning trades. Suppose you lose in 1 lot, gain on 5 lots, the average gaining opportunity become much higher.

Turtle Trading System on Metastock
Here is the code for Metastock users. You can create the indicator using the following code.
H > Ref (HHV(H, 20), -1) OR L < Ref (LLV(L, 20), -1);
H = Today’s high; L = Today’s low
HHV (H, 20) = Highest value that the high price (H) has reached in the previous 20 days.
LLV (L, 20) = Lowest value that the low price (L) has reached in the previous 20 days.
Ref (HHV(H, 20), -1) = The highest high price in the last 20 days refers to last day.
Ref (LLV(L, 20), -1) = The lowest low price in the last 20 days refers to last day.

Turtle Trading With Zerodha Kite
How to create a Turtle Trading System in Zerodha Kite?
- Login to Zerodha Kite and open your chart
First login to your Zerodha Kite and open the stock or index you want to trade. Here I opened the Nifty index chart.
- Attach the Donchian Channel indicator
Next, I attached the Donchian Channel indicator. I kept the default value, 20-day high period and 20-day low period. So this channel will plot lines at 20-day high and 20-day low levels.
- The trading rules
We can take a buy trade if the price candle closes above the 20-period Donchian channel peak. Exit the buy trade if the price closes below the middle band. Similarly, we can take a short sell trade if the price candle closes below the 20-period Donchian Channel trough. Exit the short trade if the price closes above the middle band.

The best book on this subject is Way of the Turtle: The Secret Methods that Turned Ordinary People into Legendary Traders written by Curtis M. Faith.
Curtis was one of the original students of Richard Dennis. He was one of the Turtles of 1983 batch. So, this book is directly from the horse’s mouth. A must-read for them who want to know the mechanical system correctly.
