Was working on regular vortex and found a problem with this version, hopefully corrected in this version.mrtools wrote: ↑Sat May 08, 2021 3:26 amThis is a bit updated and optimized version of Mladen's dynamic zone vortex.
Interesting information about Vortex:::
According to original description of the authors (Etienne Botes and Douglas Siepman) of the Vortex indicator:
After thoroughly researching technical tools, we concluded that the concept of the Directional Movement Index (DMI) offered the most accurate way to identify trend direction or significant price moves in the market. The concept of DMI was best defined and described by J. Welles Wilder in his classic 1978 book "New Concepts In Technical Trading Systems". The result of his work is the now-famous and highly effective indicator, which inspired the creation of our Vortex indicator.
To understand the Vortex indicator better, we must describe directional movement. The idea is that the individual relationship between price bars provides clues to the direction of the trend or market. Wilder summed it up thus: "Directional movement is the largest part of today's range that is outside yesterday's range."
Positive directional movement is simply the portion of a price bar that is above the high of the previous bar. Negative directional movement is the portion of the price bar that is lower than the previous low. The smaller of these two values is assigned a zero value. The larger number is used to indicate if the market is moving up (positive) or down (negative). In the case of an inside bar (if neither the high nor the low is higher or lower than the previous bar), a zero value is assigned to both positive and negative direction.
The result will be a string of seemingly random consecutive zeroes or positive numbers placed in two columns assigned for positive and negative directional movement. However, if these two strings of numbers are summed after 14, 21, or 55 periods, the larger value gives an indication of overall trend. If this process is continued, the result can be seen on a chart as two lines representing positive and negative directional movement. These will intersect and cross during a change of trend and diverge wider and wider as the strength of the trend increases. This is the basis of Wilder's DMI.
The article was published in the January 2010 issue of TASC.
