Hi Collector, one thing I'd b very interested to see would be the possibility to
draw Range Bars. Sometimes referred to as Constant Range Bars or Nicolellis range
bars they basically ignore the time element and will form a new bar after a specific
range has been covered low to high or high to low. Below is a brief description
of what I mean:
Range Bars are price-driven bars, with each bar having a required minimum high-low range.
Once the range requirement is reached, the first tick to break outside that range
will begin a new bar (and become the opening price of that new bar). A 0. 75 Range
Bar chart of ES with volume can be seen below. Notice that the height/range of
each bar is 0.75. Also notice that each bar opens at a price outside of the high/low
range of the previous bar. And last, notice that each bar closes at either it's
high or it's low. These are the three rules of range bars.

- Each bar must have a high/low range equal to the range specified. The high/low range
of a bar can exceed the range specified in certain situations (gaps) but can never
be less that the range specified.
- Each bar must open outside the high/low range of the previous bar.
- Each bar must close at either it's high or it's low.
With Range Bars (and Change Bars), new bars will only be formed when price is moving.
When prices gets stuck in a tight range for an extended period of time, horizontal
screen real estate will not be wasted with multiple bars that would have formed
had the periodicity been volume or time driven.
For Range Bars, the high/low range of each bar is essentially held constant, while
time and volume are variables.
