The Vertical Horizontal Filter on IQ Option

The Vertical Horizontal Filter was first introduced in the magazine “Issues of Futures”. It was developed by Adam White in 1991. Traders use it to determine whether the market is trending or not.

Setting up the chart

In order to use any indicator, you must first attach it to your chart. Before you can do that, however, you should be logged in to your trading account and make a few decisions such as what kind of asset you are going to trade, how much money you will invest in a single trade, how long your transactions should last, how big loss you can handle. Once you have it clear, go to the indicators icon and choose ‘Trend'. The Vertical Horizontal Filter will be on the list displayed on the right side. Click on its name and it will be added to your chart. Now you can start using it.

The period of the Vertical Horizontal Filter is 28 by default. You may choose to change it if it suits your strategy better. Then, a different value will be taken into the calculations. The number of periods is defined as n.

When you know your n, you have to find the highest closing price (HCP) within the period. Then, identify the lowest closing price (LCP). You will also have to determine the change in the closing price for every period that is to subtracting the closing price from yesterday from today's closing price. Repeat this step for n periods and you will receive a sum of absolute values for n periods. Divide the difference between the HCP and LCP by this sum and the calculations for the VHF will be done.

VHF = (HCP – LCP) / sum of absolute values for n periods

How to read the Vertical Horizontal Filter indicator

The VHF is utilised by traders to determine future trends. In general, when the indicator is moving upwards, the market is trending. When the indicator is moving downwards it means the market is in the ranging phase.

It is possible to forecast future price movement by observing the indicator's line. When it rises extremely high, you may expect the congestion phase is coming. When the indicator reaches extreme low values, a trend is forming.

The Vertical Horizontal Filter is a trend following indicator. It can be utilised to determine whether the market is trending (rising VHF) or ranging (falling VHF). Moreover, traders may predict the future beginning (extremely low values of the VHF) or the end (extremely high values) of the trend.

Note that the indicator does not reveal the direction of the trend nor provide the trading signals. To determine the best point to open or close your transactions you should use some additional technical analysis tools.
