This is the usual SAR indicator which can be applied on single price sources, for example on close price only or on the results of another indicator. This indicator can be very useful for the strategies such as described by the following link: http://forex-strategies-revealed.com/system-2sarstogo
This strategy proposes to apply SAR on MACD results. This is not possible with the regular SAR because it requires the whole bar to be calculated. In such cases use presented tick_sar indicator instead, just choose the price or indicator you want apply SAR to on the source tab of the indicator properties. Please see an example of SAR indicator applied on MACD results.
