When to switch from Rising Parabolic SAR to Falling Parabolic SAR?
I want to calculate the Parabolic SAR indicator. I have the usual formula
Prior SAR: The SAR value for the previous period.
Extreme Point (EP): The highest high of the current uptrend.
Acceleration Factor (AF): Starting at .02, AF increases by .02 each time the extreme point
makes a new high. AF can reach a maximum of .20, no matter how long the uptrend extends.
Current Rising SAR = Prior SAR + Prior AF(Prior EP - Prior SAR)
and I plan to use a similar formula for Falling SAR
. My question is, how should I determine when to switch from Rising SAR
to Falling SAR
? Also, how do I know when I have to drop the EP
value? My guess is that when I "see an uptrend", I have to consider Rising SAR
, and my EP
should be the maximum from the start of the uptrend. But how do I identify the uptrend?
I plan to perform calculations in Python using Pandas. Any comment on what I should be aware of is appreciated!
