    Murphy's Laws of Technical Trading



    1. Map the Trends

    Study long-term charts. Begin a chart analysis with monthly and weekly charts spanning several years. A larger scale map of the market provides more visibility and a better long-term perspective on a market. Once the long-term has been established, then consult daily and intra-day charts. A short-term market view alone can often be deceptive. Even if you only trade the very short term, you will do better if you're trading in the same direction as the intermediate- and longer-term trends. More Details at Gold Forecast

    2. Spot the Trend and Go With It

    Determine the trend and follow it. Market trends come in many sizes – long-term, intermediate-term and short-term. First, determine which one you're going to trade and use the appropriate chart. Make sure you trade in the direction of that trend. Buy dips if the trend is up. Sell rallies if the trend is down. If you're trading the intermediate trend, use daily and weekly charts. If you're day trading, use daily and intra-day charts. But in each case, let the longer range chart determine the trend, and then use the shorter term chart for timing. Read More at https://www.gold-pattern.com/en/gold-signals.html



    3. Find the Low and High of It

    Find support and resistance levels. The best place to buy a market is near support levels. That support is usually a previous reaction low. The best place to sell a market is near resistance levels. Resistance is usually a previous peak. After a resistance peak has been broken, it will usually provide support on subsequent pullbacks. In other words, the old “high” becomes the new low. In the same way, when a support level has been broken, it will usually produce selling on subsequent rallies – the old “low” can become the new “high.” Check: Gold Signals for more accurate information and trading Signals.



    4. Know How Far to Backtrack

    Measure percentage retracements. Market corrections up or down usually retrace a significant portion of the previous trend. You can measure the corrections in an existing trend in simple percentages. A fifty percent retracement of a prior trend is most common. A minimum retracement is usually one-third of the prior trend. The maximum retracement is usually two-thirds. Fibonacci Retracements1) of 38% and 62% are also worth watching. During a pullback in an uptrend, therefore, initial buy points are in the 33-38% retracement area. Check more at https://www.gold-pattern.com/en/gold-forecast-prediction





    5. Draw the Line

    Draw trend lines. Trend lines are one of the simplest and most effective charting tools. All you need is a straight edge and two points on the chart. Up trend lines are drawn along two successive lows. Down trend lines are drawn along two successive peaks. Prices will often pull back to trend lines before resuming their trend. The breaking of trend lines usually signals a change in trend. A valid trend line should be touched at least three times. The longer a trend line has been in effect, and the more times it has been tested, the more important it becomes. More at https://www.gold-pattern.com/en/gold-signals.html



    6. Follow that Average

    Follow moving averages. Price moves above or below moving averages provide objective buy and sell signals. They tell you if the existing trend is still in motion and they help confirm trend changes. Moving averages do not tell you in advance, however, that a trend change is imminent. In stock trading, the three most important ones are the 20-day average for short-term trends, 50-day for intermediate trends, and 200-day for major trends. Crossings of two moving averages also provide trading signals. Three popular combinations are 5-20 days, 20-50 days, and 50-200 days. Exponential moving averages (EMAs) are usually more suitable for spotting moving average crossings. https://www.gold-pattern.com/en

    7. Learn the Turns

    Track oscillators. Oscillators help identify overbought and oversold markets. While moving averages offer confirmation of a market trend change, oscillators often help warn us in advance that a market has rallied or fallen too far and will soon turn. Two of the most popular are the Relative Strength Index (RSI) and the Stochastics Oscillator. They both work on a scale of 0 to 100. With the RSI, readings over 70 are overbought while readings below 30 are oversold. The overbought and oversold values for Stochastics are 80 and 20. Most traders use 14 days or weeks for Stochastics and either 9 or 14 days or weeks for RSI. Oscillator divergences often warn of market turns. These tools work best in a trading market range. Weekly signals can be used as filters on daily signals. Daily signals can be used as filters for intra-day charts. More at https://www.gold-pattern.com/en/gold-signals.html
