Moving Average Convergence Divergence (MACD pronounced Mac Dee) is the difference between the 26 day and 12 day exponential moving averages. A 9 day exponential moving average called the signal line or a trigger line is plotted on top of MACD to show buy/sell opportunities.
You can use MACD in three ways: Crossover, overbought/oversold conditions and divergences. In wide swinging markets, MACD proves most effective. When MACD falls below the signal line, the basic rule is to sell. Similarly, when MACD rises above the signal line and cuts it from below, it is a buy signal.
When the shorter moving average pulls away from the longer moving average, it is likely the price is overextended itself. This indicates, it will comeback to the realistic levels soon. MACD is also very useful tool in telling whether the market is overbought or oversold.
An indication that an end to the current trend may occur soon is when MACD diverges from the currency pair. A bearish divergence occurs when MACD is making new lows and the currency price fails to reach those lows. Similarly, a bullish divergence occurs when the MACD is making new highs but the currency price fails to reach those highs.
Momentum is an oscillator that indicates the rate of price change not the actual price level and it is the net difference between the currency pair closing price and the oldest closing price from the predetermined period. The signal is triggered when the oscillator crosses the zero line. The more responsive the momentum oscillator will be to the short term price fluctuations, the shorter the number of days included in the calculations.
Another important technical indicator is the Relative Strength Index (RSI) and it indicates a markets current strength or weaknesses depending on where the prices close during a given period. RSI is plotted on a scale of 01-100 and a buy signal is triggered when RSI moves up from the lower band above 30. Similarly, a sell signal is triggered when RSI moves down from the upper band and comes down below a level usually set at 70.
Rate of Change (ROC) is another version of momentum oscillator is calculated by dividing the current closing price with the oldest closing price instead of subtracting the oldest closing price from the current closing price as in the momentum oscillator. It is sometimes used.
One of the most popular indictors is the Volume Indicator. A movement accompanied by an increasing volume is more likely to continue in strength than a movement accompanied with decreasing volume which is likely to fade away. It is used to show the strength of an up or down movement.
Many traders use volume indicator as their only technical indicator in trading. Others use it in conjunction with price charts and fundamental analysis like economic news and geopolitical news. The Volume Indicator is a great source of confirmation. It gives entry and exit signals and helps in overall trading. You should learn to use these technical indicators. You should become comfortable in using them. Use them to discern trends on different currency pairs and time intervals.
