Forex Indicators
| Forex Indicator Definitions Simple Moving Average (SMA) - The average price of a given time period, (5 minutes, 10 minutes, 1 day, etc.) where each of the chosen periods carries the same weight for the average. Example using the closing prices of the USD/JPY currency pair: Day 1 close = 124.00, Day 2 close = 126.00, Day 3 close = 124.00, Day 4 close = 126.00; The 4-day SMA is 125.00 (the average of the prior four closes). Exponential Moving Average (EMA) - Here, the averages are calculated with the recent forex rates carrying more weight in the overall average; for example: In a 10-day exponential moving average, the last 5 days will have more effect on the average than the first 5 days. The idea is to use the most recent data as a better indication of trend direction. Bollinger Bands - The basic interpretation of Bollinger Bands is that prices tend to stay within the upper and lower bands. The distinctive characteristic of Bollinger Bands is that the spacing between the bands varies based on the volatility of the prices. During periods of extreme currency price changes (i.e., high volatility), the bands widen to become more forgiving. During periods of low volatility, the bands narrow to contain currency prices. The bands are plotted two standard deviations above and below a simple moving average. They indicate a "sell" when above the moving average (or close to the upper band) and a "buy" when below it (or close to the lower band). The bands are used by some forex traders in conjunction with other analyses, including RSI, MACD, CCI, and Rate of Change. Parabolic SAR - The Parabolic SAR (stop-and-reversal) is a time/price trend following system used to set trailing price stops. The Parabolic SAR provides excellent exit points. Forex traders using this technical indicator should close long positions when the price falls below the SAR and close short positions when the price rises above the SAR. If you are long (i.e., the price is above the SAR), the SAR will move up every day, regardless of the direction the price is moving. The amount the SAR moves up depends on the amount that currency rates move. |
