This chart is just a single line plot based on the day's close value. The ChartPrefs menu enables choice of a different value, e.g. open price.
The Default Plot setting toggles the use of the user defined formula
with the default setting of the Close bar.
Here the above shot is a formula that creates the formula of (High +
Low + Close) / 3. Lets break it down into each step.
Step 1 uses
the REF plugin to get an array of High bars.
Step 2 uses
the REF plugin to get an array of Low bars.
Step 3 uses
the REF plugin to get an array of Close bars.
Step 4 uses
the MATH plugin to add steps 1 and 2 together.
Step 5 uses
the MATH plugin to add steps 4 and 3 together to complete the (High +
Low + Close) portion of the formula.
Step 6 uses the MATH plugin to divide steps 5 by 3. This step contains
the average price, and so we check the plot column to tell qtstalker
that this is the line we want to plot.
