Volatility refers to the rate of change of a certain financial asset like stock, currency, index, or cryptocurrency. A company whose share price is consolidating is said to have low volatility. On the other hand, a firm whose shares move up and down is said to be highly volatile.
In most cases, day traders prefer companies with high volatility because it tends to lead to more profitability. In this article, we will look at what historical volatility is and how you can use it in the market well.

What is volatility?
The concept of volatility is important in the market. As an example, most investment banks like Goldman Sachs and Morgan Stanley recorded substantial trading profits in 2020 amid the global pandemic.
This happened since 2020 was one of the most volatile years in the recent past because of the risks brought about by the pandemic. On the other hand, these companies tend to make less money in periods of low volatility.

What is the difference between historical and implied volatility?
There are generally two main types of volatility that you need to know about. First, there is historic volatility, which refers to how a price deviates from its past overall price in a certain period of time.
Second, there is implied volatility, which basically looks into the future and how volatile a stock could become. This IV is mostly useful in the options trading industry.
What is the Historic volatility indicator?
To measure the historic volatility, day traders use an indicator known as Historic volatility that is built-in the TradingView platform. One can also download and install the indicator in other platforms like the MetaTrader.
When applied, the indicator is simply a line that moves up and down.
The historic volatility is a relatively difficult indicator to calculate. However, like all indicators, it is not always necessary for you as a trader to know how it is calculated. All you need to know is how to apply it in a chart and predict the future price.
The formula for calculating the Historic volatility is as shown below:
In this formula, R sub i through n is the continuously compounded return for each period. R avg, on the other hand is the average of the daily returns.
The chart below shows the Historic volatility applied in the daily chart of Tesla.
How to use the Historic Volatility indicator
The HV indicator is unlike other indicators that we have looked before. Unlike indicators like the moving average and Relative Strength Index (RSI), the Historic Volatility indicator does not tell you when to buy or sell an asset. It does not also identify overbought and oversold levels.
Instead, the indicator is merely a guide of what is happening in a financial asset.
For example, if the HV rises, it means that a company’s stock or currency is getting highly volatile. Therefore, as a trader, you should dig deeper into the firm and see why this is happening.
You can achieve this by looking at the recent news from major sources like Bloomberg and Yahoo Finance. After this, you can use this knowledge to make better decisions on whether to buy the stock or short it.
