- RSI (Relative Strength Index) is a momentum oscillator that compares the magnitude of a stock's recent gains to the magnitude of its recent losses to provide overbought and oversold signals. Recommended levels are 70 for overbought and 30 for oversold.
- Williams %R is a momentum indicator that also attempts to measure overbought and and oversold levels on a scale that ranges from 0 to -100. 0 to - 20 can be considered overbought and -80 to -100 oversold. It shows the relationship of the close relatrive to the high-low rangfe over a set period of time. The nearer the close is to the top of the range, the nearer to zero (higher) the indicator will be. Vice versa for nearer the close is to the bottom of the range.
- %R = [(highest high over ? periods - close)/(highest high over ? periods - lowest low over ? periods)] * -100
- Money Flow Index (MFI) is a momentum indicator similar to RSI, it is more volume-weighted and a good measure of strength of money flowing in and out of security. It compares "positive money flow" to "negative money flow" to create an indicator that can be compared to price in oder to identify strength or weakness of a trend.
- Money Flow = Typical Price X Volume
- Money Ratio = Positive Money Flow / Negative Money Flow
- Money Flow Index = 100 - (100/(1+Money Ratio))
