Description
Wilder's Parabolic Stop And Reverse
Syntax
SAR(dir {0}, accel {0.02}, max {0.2}, len {100})
Parameters
dir - the trend direction to use
accel {0.02} - initial acceleration factor
max {0.2} - maximum acceleration factor
len {100} - number of bars to use in the calculation
(any of the above can be any formula)
Notes
Implements the Parabolic Time/Price System as an indicator function for use in trading strategies.
To calculate SAR using a value series other than Close, use SarF.
The dir parameter (trend direction) is interpreted as follows:
•the default value of 0 means to follow the trend as in the original indicator, i.e. to return a long exit price during an up-trend or a short exit price during a down trend
•a positive value means always return the long stop price
•a negative value means always return the short stop price
