I often use BB and RSI indicators on the chart because they offer the precise indications needed on a particular given average time, to know how accurate they were from the use of SAR, you can set in the three in predicting toward what the market pattern is likely going and guess on the direction as well for the price and you will discover the it will be only SAR that will give a different indication while the other two will be almost accurate in their own prediction, i also think that many finds it more earlier to use the RSI and BB indicators more conveniently than they find with the use of SAR.
