The PSAR Indicator is a trendfollower, displaying the distance  from  a trailing stop in points. Positive values indicate an uptrend and vice versa.  A Reversal is not a sell signal, often leads to a move into the opposite  direction because a short spike can trigger a reversal. The Fibonacci Supertrend is holding steady  until a new high or low of  a certain period and percentage is marked. A plus in the Fibonacci Supertrend means that a long term  uptrend  is still vaild, even if a stock is trading below, but remaining below it for too long contains risk of a reversal, same in a downtrend.  The levels often act as magnets.
