Vertical Horizontal Filter was initiated by Adam White. It was first published in a magazine called “Issues of Futures” in August, 1991. The Vertical Horizontal Filter (VHF) is a very common Indicator used by traders to find out the Phase of a Price Trend. Normally, a price trend can be in a Trending Phase or a Congestion Phase/Choppy Movement Phase. Adam White created this particular Technical Indicator to determine whether prices are trending in a particular direction or are they going through a transitional period. He used it to measure the range of Futures available in the market.
