TD Pressure Parameters
This study draws a graph of accumulation/distribution pressure. Optionally,
dotted reference lines can be drawn at user-set values, but these lines do not
affect the calculation or display of the TDPRS line itself.
At each bar, TDPRS computes a price ratio and then optionally multiplies this
by the volume. Several different price ratios are available:
Close - Open
Close - Prior_Close
Different calculation is applied if the opening price is more than a threshold
percentage away from the prior close. If Open is more than P% greater than
the prior close, then instead compute:
In either case, the result is optionally multiplied by volume.
TDPRS outputs a gap at any gap bar, but gap bars are ignored in looking back
to find the prior close value.
The study command for Pressure is .TDPRS.
