Historical past and method:The Tick Quantity Indicator was invented by William Blau and has been revealed in his e-book "勢頭, Path and Divergence" (1995, web page forty three). The indicator begins with separating the upticks and downticks in every worth bar. The ensuing arrays are smoothed with DEMA (two-cross EMA with durations r 和 秒 隨後). The uncooked TVI is calculated with the next formulation:
TVI_Raw = one hundred * ---------------------------------
... and the ultimate TVI form is made by further EMA smoothing with a interval of u. Utilization:In addition to utilizing TVI for divergence, I've discovered the change of TVI slope to be a really helpful and exact proxy for change in worth path, particularly in durations of excessive volatility briefly timeframes. Different MQL4 variations:The indicator was carried out in MQL4 by Profitrader a few years in the past, utilizing all out there buffers for calculations and plotting a single line. I've discovered a number of coloured histogram variations throughout the Internet, all of them referred to as the tvi.mq4 by way of iCustom() and all repaint due to poor coding. So I made a decision to make myself a correct stand-alone histogram variant. 7 native buffers and 6 additional buffers (by way of arrays) 被使用. It is going to by no means repaint.
