Ruby Technical Analysis

Description

The Qstick indicator is a technical analysis indicator developed by Tushar Chande to numerically identify trends on a price chart. It is calculated by taking an 'n' period moving average of the difference between the open and closing prices. A Qstick value greater than zero means that the majority of the last 'n' days have been up, indicating that buying pressure has been increasing.

The Qstick Indicator is also called Quick Stick. It is not widely available in trading and charting software.
