hi Tomasz,
Similar to classic pivot levels and Camarilla
levels I would like to use the Value Area of the previous day to plot on the
current day and use it for backtesting purposes, similar to the Camarilla level
chart I added in my previous post.
For instance I could imagine a function in
Amibroker that looks like
VAH =
getUpperValueArea(inDaily,70,-1);
which would give me (using the 5-min chart) the
upper value area where 70 percent of the volume in concentrated of the previous
day.
Ofcourse, I am not sure how this could best be
implemented in Amibroker, but it is pretty tough to program in AFL when you want
to keep it speedy.
regards, Ed

The problem is that Market Profile by nature looks into the
future (i.e. the bars displayed at the "beginning of the day" cover entire day
going forward),
so when trying to backtest this you will know at 9:30 what
"all-day" levels are and you will be looking into the future that
way.

to elaborate a bit on this (maybe Tomasz
Janeczko is reading and I know this stuff is planned to be added to
Amibroker) personally I am most interested to be able to access levels to be
able to do backtesting.
For instance the chart below shows intraday
Camarilla levels that can be used for support and resistance and I can test
stratigies to use them for trading. So you want to be able to define
the time interval you want to derive the "market
profile" from and expand the resulting data to the timeframe in which
you like to use these "market profile" levels for trading. Levels
are:
POC
VAH
VAL

Keith,
pretty simple. The value area is the price
range where in 70% of the volume is traded and the point of control
the price interval / step at which the most volume is traded that
day.
it are areas where traders look for support
and resistance and this stuff is very popular at the moment with traders
so there is where you need to be. It is with all these levels, classic
pivots, Camarilla etc they work because lots of traders use
them. This subject on the market profile I believe is first described
by: http://www.profiletrading.com/book.htm
To find the VA (value area) you need to step
through the entire price range of the day and find how much volume is
traded within a certain price interval / step. This is a very time
consuming process and to my knowledge Amibroker's AFL language
is not very suitable for these type of calculation. Because in Amibroker
arrays by default span the entire data range and for these type of
calculations you need to be able to define smaller arrays and be able to
do array based operations on them.

Ed -- I'm just
returning from, Investopedia.com, EliteTrader.com, or
AmiBroker Help. So, I give up. What are Value Area and
POC?
Thanks, -- Keith

Keith, no started this today. Wanted to
know if somebody programmed the market profile (POC and VA) in
Amibroker Formula Language (AFL). I found some code and done some
myself but this is real slow. Link to existing code on inditrader.com
board I posted in a later post.

Ed -- It looks to
me as if you are continuing a discussion regarding some AFL.
But you changed the Subject name, and deleted any previous posting
from your posting.
So, in light of the above, when you ask,
"anyone managed to program this in
AFL or a plugin?", what in h... AFL are you talking about? --
Keith

hi,

designed to display the last few days. I am interested in code
that generates the upper/lower value area and POC for
backtesting purposes. But it seems you need some clever
programming to make this usable else it will be very
slow. The code I found sofar is slow indeed and I can't come up
with something smart either. Try loading 2 years of 5 minute data
and AB locks up completely. Camarilla is a nice substitute but as
I read somewhere "Camarilla is the poor man's Market
Profile",
