Introduction
The Rainbow Strategy is a straightforward, mechanical trend-following system designed to keep traders in the market during major moves. By using multiple moving averages of varying lengths, the strategy helps visualize momentum and provides clear rules for when to enter and exit. While it is not revolutionary, its simplicity and mechanical nature make it ideal for those who want to remove emotion from their trading decisions.
What is the Rainbow Strategy?
The Rainbow Strategy is a trend-following system that employs a series of moving averages to determine the market's direction and momentum.
-
Mechanical Nature: It has a clear set of rules for both entry and exit, reducing the need for subjective decision-making.
-
Momentum Visualization: The "rainbow" of moving averages illustrates when momentum is strong and when it is beginning to fade.
Moving Average Configuration
The strategy typically uses four exponential moving averages (EMAs) to create a wide "band" of indicators.
-
The 10 EMA (Red): The shortest average, tracking immediate price action.
-
The 20 EMA (Orange): Short-term momentum.
-
The 30 EMA (Green): Medium-term momentum.
-
The 40 EMA (Blue): The longest average, serving as the baseline for the trend.
-
Spacing: It is important to use a wide band of numbers (like 10, 20, 30, 40) rather than tight spacing to ensure the market has truly committed to a direction.
Rules for Entry: The "Fan Out"
The signal to enter a trade occurs when the moving averages begin to align and spread apart.
-
The Setup: Look for an area where all four moving averages start to point in the same direction and "spread out" nicely.
-
Execution: Once the "fan out" is visible, you enter the trade in the direction of the slope. For example, on the AUD/USD 1-hour chart, a signal at 0.6619 kept a trader in the market for a significant move higher.
Rules for Exit: The Crossover
The strategy does not rely on fixed profit targets; instead, it aims to "squeeze every last pip" out of a trend.
-
The Exit Trigger: You close your position when the shortest moving average (10 EMA) crosses the longest moving average (40 EMA).
-
Example: In a major move on the NZD/JPY pair, an entry at 98.27 Yen was not closed until the 10 EMA crossed back above the 40 EMA at roughly 90.58, capturing a massive profit.
Managing Risk in Choppy Markets
Like all trend-following systems, the Rainbow Strategy can struggle when markets are moving sideways.
-
Small Losses: During choppy periods, the 10 EMA may cross the 40 EMA shortly after entry, leading to small losses (e.g., five pips).
-
Long-Term Trend Filter: To avoid being "chopped up," it is highly recommended to trade in the direction of the longer-term trend found on the weekly chart.
Strategy Examples and Long-Term Trends
The system works effectively on various asset classes and time frames:
-
Indices (NASDAQ 100): A crossover on the 1-hour chart around 18,200 points stayed in until 19,797, yielding massive gains.
-
Daily Charts: On the NASDAQ daily chart, entries around 15,000 were not exited until 18,000, illustrating the system's power on higher time frames.
-
Conclusion: As long as the market is not going sideways, the large profits captured by staying in major trends will far outweigh the small losses from occasional choppiness.
