Introduction
The 80/20 Trading System is a mechanical, trend-following strategy designed for traders who need a simple, "set-and-forget" approach. Developed by Chris Lewis to fit a busy work schedule, the system removes the psychological stress of trying to perfectly time market tops or bottoms. Instead, it focuses on capturing the middle 80% of a move using a high reward-to-risk ratio based on psychological "round numbers".
The Philosophy of the 80/20 System
The core premise is that professional traders rarely "top-tick" or "bottom-tick" a move; instead, they focus on the bulk of the trend.
-
Mechanical Approach: The system uses strict rules for entry, stop-loss, and take-profit, making it ideal for those who cannot watch the screen all day.
-
Trend Priority: Success relies on trading exclusively in the direction of the long-term trend.
-
Reward-to-Risk: The system typically aims to gain 80 pips while risking only 20 to 30 pips.
Identifying the Daily Trend
Before placing any trades, you must determine the market's direction on a higher time frame.
-
The Daily Filter: Use the Daily chart to establish the trend.
-
Moving Average: Apply an Exponential Moving Average (EMA). Chris Lewis recommends the 50-day EMA, though a 20-day EMA can be used for faster involvement.
-
The Rule: You only look for buy trades if the EMA is sloping upward and sell trades if it is sloping downward.
Setting Up the 4-Hour "Big Figures"
Once the daily trend is established, move to the 4-hour chart for execution.
-
Big Round Figures: Plot lines every 100 pips (e.g., 0.6500, 0.6600, 0.6700). These "big figures" are psychologically significant areas where banks and institutions often place large orders.
-
Ignore the MA: On the 4-hour chart, the moving average is ignored; it is only used on the daily chart for direction.
Entry and Exit Rules: The 80/20 Mechanics
In an uptrend (as seen in the AUD/USD example):
-
Entry: Place a buy order at the "20 level" above a big figure (e.g., 0.6620).
-
Take Profit: Set your target at the next big figure (e.g., 0.6700), which is an 80-pip gain.
-
Stop Loss: Place your stop-loss just below the big figure (e.g., 0.6590 or 0.6600), representing a 20 to 30-pip risk.
Conservative Adjustments (The 80/30 Variation)
If you are risk-averse, you can give the trade more room to breathe.
-
The 80/30 Rule: By placing your stop-loss 10 pips below the big figure instead of at the big figure, you risk 30 pips to gain 80.
-
Benefit: This extra 10 pips can keep you in a trade during a minor pullback or "retest" of the big figure before the trend continues.
-
Risk/Reward: Even at 30 pips risk for an 80-pip gain, the reward-to-risk ratio remains better than 2:1.
Strategy Examples and Psychology
The system's strength lies in its ability to handle minor losses while capturing large trends.
-
USD/CHF Downtrend: Following a 50-day EMA slope on the daily chart, a trader could have taken multiple 80-pip wins as the pair dropped across several "handles" or 100-pip ranges.
-
Psychological Advantage: Because the entry, stop, and target are set in advance, the trader does not have to worry about market fluctuations or emotional decision-making.
-
Long-Term Utility: When caught in a strong trend, such as a major currency plunge, this system can provide multiple profitable entry points over weeks or even months.
