favorite Copper contracts
The Question : To anticipate the next bar Low.
The main Hypothesis : Next bar RSI() will not be lower than
min(RSIA(H,14),min(RSIA(L,14),RSIA(C,14)))
Test period=the last 200 bars
Errors:
Error05<0.5%
Error1<1%
Error2<2%
Statistics:
Longterm05, the percentage of error<0.5% for the last 200
bars
Longterm1, the percentage of error<1% for the last 200
bars
Longterm2, for error<2%
The first attempt to answer:

Some first notes now :
*The 10-bar red line is today support, already known from
yesterday.
*The 3-bar yellow line is the prediction for the next bar
Low.
*As soon as you download intraday EOD for the new day,
a. the yellow line will automatically
become red and will be the same for the whole session. It
is the intraday support.
b. a new yellow line will appear.
It is the next [unknown] bar support, it is variable as
new OHLC come and will have
its final price
by the end of the session.After the first half of the
session, this yellow line [with a reliability confirmation]
is very
interesting, especially when you see high volume
positions at this level. Sometimes you will have the
impression
that some other
people also "know" your secret yellow line.
*Highly volatile stocks [MA(H/L,200)>1.08 !!] are not
that reliable and should be handled with care.
*Change the filter condition to
Filter=Approx05;
or
Filter=Approx1;
or
Filter=Approx2;
explore for the n=1 last quotations
to see the stocks with actual/predicted Low less than 0.55,
1% and 2% respectively. for the June16 N100 session we saw
86 stocks with 2% approximation, 68 stocks with 1% and 31
stocks with just 0.5%. Not bad at all for a positive biased
day.
*FACTOR may vary between 0.2 to 0.5 with similar
results.
*Red and yellow line at tha same level may denote
accumulation at this level and [probably] a turning point...
The attached gif explains why Copper is my favorite. It was
90% reliable, ie for 180 of the last 200 bars the error
between
predicted and actual Low was less than 2%. For 126/200 bars
the error was less than 1%. [for 80/200 bars the error was
less
than 0.5%]
This is the first, short description of this experimental
method.
Improvements will hopefully follow.
