The list of available indicators on the IQ Option platform is growing by day. Today we are taking a closer look at a brand-new trend-following tool that can become a valuable addition to your trading system.

Ehler’s Fisher Transform, developed and introduced by J.F. Ehlers, is a popular technical analysis indicator that transforms the asset price into a Gaussian normal distribution. It may sound intimidating in the beginning but once you grasp its core concept, you will get a better understanding of how it works. Read the full article to learn how Fisher Transform works and use it in trading. Note that this indicator works on all assets and timeframes.

## How it works?

Since we’ve mentioned a normal distribution, it would be wise to provide a basic explanation of this concept. A normal distribution (also called the bell curve) is a common probability distribution. For a normally distributed data set, the following will be true:

• the Mean value is equal to the Median value;
• the left and the right halves of the graph are symmetrical.

This is how it looks on a graph.

A lot of things follow a normal distribution: heights of people, errors in measurements, blood pressure, marks on a test etc. However, there are also quantitative variables that do not follow a normal distribution, and the asset price is one of them. It makes them hard to predict and analyze.

This is all theory. Now, let’s get to practice.

## How to use in trading?

Ehler’s Fisher Transform transfigures prices into a normal distribution that can later be used in technical analysis. Since the indicator follows a normal distribution, extreme values of the indicator (both positive and negative) are quite uncommon. What does that mean for you? When Fisher Transform is above the zero line and goes up, the asset is overbought. When Fisher Transform is below the zero line and goes down, the asset is oversold. In both cases, the probability of a trend reversal gets higher with time. When receiving a buy or sell signal from another indicator, that confirms the signal sent by Fisher, traders consider opening a corresponding position.

Fisher Transform is usually compared to the Stochastic Oscillator. In fact, both work in a very similar fashion, demonstrating overbought and oversold positions, thus hinting at the moments when a price reversal can be expected. As with the Stochastic, when using Fisher Transform, you would want to use additional indicators to confirm its signals.

## How to set up?

In order to use the Ehler’s Fisher Transform indicator in trading, click on the “Indicators” button in the bottom left corner of the screen and proceed to the “Trend” tab. Then choose Ehler’s Fisher Transform from the list of possible indicators.

Click “Apply” if you want to use the indicator with standard parameters. Or you can adjust its period for higher accuracy / fewer false alarms. The indicator is ready to use.

Now, when you know how to trade using Ehler’s Fisher Transform, you can proceed to the trading platform and try this indicator yourself.
