Question 1

What does Parabolic SAR show?

Accepted Answer

Dots that trail price: below the candles in an uptrend and above them in a downtrend. Each dot is a possible stop level that follows the move.

Question 2

How is Parabolic SAR built?

Accepted Answer

The dot moves toward price by a step that grows each time a new extreme is made, up to a limit. When price touches the dot, the indicator reverses and starts on the other side. Default: Start 0.02, increment 0.02, maximum 0.2.

Question 3

How do traders read Parabolic SAR?

Accepted Answer

Dots below price: uptrend. Dots above: downtrend. A flip to the other side marks a reversal of the trailing stop. In sideways markets it flips often and gives many false signals.
