John Murphy, a giant in the field of technical analysis, distilled his decades of experience into 10 essential laws of technical trading. These laws provide a timeless framework for traders to approach the market with discipline and a clear plan. While some of these laws may seem simple, they are profound in their application and can make the difference between success and failure in the market.

1. Map the Trends

Murphy's first law is to study the long-term charts. Start with a monthly and weekly chart spanning several years. This will give you a big-picture perspective on the market and help you to identify the primary trend. The primary trend is the most important factor in your trading decisions. You should always trade in the direction of the primary trend.

2. Spot the Trend and Go With It

Once you have identified the primary trend, your goal is to trade in the direction of that trend. This means buying on dips in an uptrend and selling on rallies in a downtrend. It is much easier to make money by swimming with the tide than by swimming against it.

3. Find the Low and High of It

Use support and resistance levels to identify entry and exit points. Support is a price level where buying pressure is strong enough to overcome selling pressure and halt a decline. Resistance is a price level where selling pressure is strong enough to overcome buying pressure and halt a rally. These levels can be identified by looking for previous peaks and troughs on the chart.

4. Know How Far to Backtrack

Use Fibonacci retracements to measure the size of corrections within a trend. In a strong uptrend, corrections will often retrace 38.2% or 50% of the previous advance. In a weaker uptrend, corrections may retrace 61.8% of the previous advance. These levels can be used to identify potential buying opportunities.

5. Draw the Line

Trendlines are a simple but effective tool for identifying and confirming trends. An uptrend is defined by a series of higher highs and higher lows. A downtrend is defined by a series of lower highs and lower lows. A trendline can be drawn connecting the lows in an uptrend or the highs in a downtrend. A break of a trendline can be an early warning sign of a trend reversal.

6. Follow That Average

Moving averages are another useful tool for identifying and confirming trends. A moving average smooths out price data and makes it easier to see the underlying trend. The most popular moving averages are the 50-day and 200-day moving averages. A “golden cross” occurs when the 50-day moving average crosses above the 200-day moving average, which is a bullish signal. A “death cross” occurs when the 50-day moving average crosses below the 200-day moving average, which is a bearish signal.

7. Learn the Turns

Momentum oscillators, such as the Relative Strength Index (RSI) and the Stochastic Oscillator, can be used to identify overbought and oversold conditions. An overbought condition occurs when prices have risen too far, too fast and are due for a correction. An oversold condition occurs when prices have fallen too far, too fast and are due for a bounce. These indicators can be used to time entries and exits.

8. Know the Confirming Signs

Volume is a key confirming indicator. In a healthy uptrend, volume should expand on rallies and contract on declines. In a healthy downtrend, volume should expand on declines and contract on rallies. A divergence between price and volume can be a warning sign of a trend reversal.

9. Volume Is Key

This law is so important that Murphy gave it its own number. Volume precedes price. A surge in volume can be an early warning sign of a trend reversal. For example, if prices are making new highs but volume is declining, it is a sign of weakness and a potential top.

10. Know Your ABCs

Elliott Wave Theory is a complex but effective tool for analyzing the market. The basic idea is that the market moves in a series of five waves in the direction of the primary trend, followed by a three-wave correction. By understanding Elliott Wave Theory, traders can gain a deeper understanding of the market's structure and can improve their ability to forecast future price movements.

By mastering these 10 laws of technical trading, traders can develop a solid foundation for success in the market. These laws are not a magic formula, but they provide a proven framework for making sound trading decisions.
