I appreciate it Bob, TS code still might help to
understand how Wilder constructed the indicator,
thanks,

Re: [EquisMetaStock Group] Parabolic SAR formula
Bob,
if i can find the formula i think i can find a
way to implement it into metastock or at least try. I have been writing
complex codes for a while, just can't seem to find what the formula is
for SAR. It would be very helpful if you know where i can find the complex
formula of SAR.
thanks
ugur

Re: [EquisMetaStock Group] Parabolic SAR formula
Jay,
thnak you for your response but iwas more
looking for the code to plug in metastock. I have this formula
FORMULA
SAR[tomorrow]=SAR[today] + AF *
(EP[trade]-SAR[today]
DEFINITIONS
SIP=the extreme price point while in the
previous tradeAF=begins at .02 and is increased (depending on the
rules below) by .02 perday until .20AF is never increased beyond
.20EP[trade]=Extreme Price Point for the trade made so
far
but this formual is uelless unles i know is how to calculate
the SAR(today) to be able to tweak things. i can't remember the formula
that's why i was asking for the code.
Thanks,
ugur

explanation of the Parabolic SAR which is much the same as the one in
Wilder's book.<A
href="">http://www.incrediblecharts.com/technical/parabolic_sar_construction.htmTheir
explanation is below.I never tried to program it in MetaStock
because I've assumed that MetaStock has it correct, and it sure looked
that way when I was playing with it. It is like so many other
formulas that are always in the market, it works great in trending
markets but you pay a high price in choppy
markets.JayThe "formula"<FONT lang=0

<FONT lang=0

FAMILY="SANSSERIF">Construction<FONT
lang=0 face=Arial color=#000000
size=2 FAMILY="SANSSERIF">There are a few basic concepts that need
to be addressed before we can explain how Parabolic SAR is
calculated:Extreme PointThis is the highest price recorded (to
date) during a long trade or the lowest price recorded (to date)
during a short trade.Significant PointThe SP is the highest
price reached in a long trade or the lowest price reached in a short
trade. It is equal to the extreme point when a trade is
closed.Acceleration FactorThe Acceleration Factor starts at 2%
for a new trade and increases by 2% on each day that a new extreme
point is reached. The maximum acceleration factor is 20%. No further
increases are made after this figure has been reached..SAR
CalculationOn day 1 of a new trade (the day that the trade
is entered), the Parabolic SAR is taken as the significant point from
the previous trade.If the trade is Long the SP will be the extreme
Low reached in the previous trade.If the trade is Short then the
SP will be the extreme High reached in the previous trade.To
calculate Parabolic SAR for the following day: Take the difference
between the extreme point and the SAR (on day 1) and multiply by the
acceleration factor. If the trade is Long, add the result to the
SAR on day 1. If the trade is Short, subtract the result from the
SAR on day 1.There is one exception:Parabolic SAR is never
moved within the range of the current or previous day (highest High to
lowest Low over the 2 days).If this occurs in a long trade, use
the lowest Low over the 2 days as SAR for the following day.If
short, use the highest High over the 2 days as SAR for the following
day.Repeat the Parabolic SAR calculation for each subsequent
day, adjusting the Acceleration Factor whenever a new extreme point is
recorded.The trade is reversed when price equals the Parabolic
SAR for the day.
