RSI and SAR

RSI - Relative Strength Index
In many ways RSI can be considered a second form of Stochastic Oscillator, as it’s read on the same kind of charts and used the same way. The way it works is to take the ratio of the upward closings against the downward closings. When the ratio trends up, the currency is heading into overbought territory and when it trends down it’s trending into oversold territory.
Where the stochastic indicators are usually triggered at 80 and 20, the RSI can be considered more sensitive with scores of 70 or above indicating overbought while 30 or below can indicate oversold.
