DLL's for  
Instead of defining support and resistance levels in a classical manner
(function of
Open High Low, Close of the previous daily bar),
we determine the values from a
statistical point of view.
Two information are of interest: The price level of the accumulation peaks
(usually acting as support/ resistance) and the
price level of valley
(this is where the major moves appear, speed increases,
and their use is more obvious
than the peaks accumulation of prices).
This piece of code has more than 20 customizable inputs,
allowing a lot of
displays, filtering and extracting methods of the price
and tic volume distribution
levels.
Even historical distribution can be imported, concatened with the current one,
and a
dampening efect added to minimize the effect of oldest data.
The best thing to do is to carefully examine the following screenshots
with
the explanations overlaid on them.
We hope that they will make things more clear than any discurse.

Distribution of the prices (histogram is shown to the left).
This picture shows what are peaks and valley, how we define them,
and their relationship with the price levels and raw prices (prices are white bars
charts).
Notice that price levels (horizontal lines) are known in
advance and update realtime.
Also see the increase of speed prices when crossing the
valley level.

This double picture shows two Overlays on the same copy
of two
identical 10 min S&P intraday chart.
The left picture shows the 4 closest valley to the active (current) price.
The right screen shows the closest valley and the above and below closest peaks.
The active valley displays as a white horizontal line.
Any white line level on the right screen matches one colored line of the left chart.
The observed jumps come from the changing situation of the closest to price valley
that moves to an other level when price changes from a gaussian distribution to a
next one.

Magenta stairs like (left) means that no price were seen above (highest valley)

A wider screen of the valley level display.
Same screen than before , but with a lower overlay resolution.
This one shows less details, but keeps more important levels.
You will have to select the rsolution that fit your needs, up to the tic level.
