Making volatility visible

What is the best time to trade? The HVH (Hourly Volatility Histogram) provides the answer by calculating the hourly volatility for each market. The most volatile times of the day, are the most interesting for traders. When markets move, opportunities arise. Using the HVH tool traders can literally see when a market is volatile and how its volatility compares to the volatility of other markets.

These are the advantages of the HVH tool:

  • Indicates the best time to trade.
  • Shows you the size of the volatility.
  • Can be used on every instrument.
  • Easy to use and easy to interpret.
  • It is FREE.


The 24 bars of the histogram correspond to the 24 hours in a day. Each bar represents an hour from 0 (0:00-0:59) to 23 (23:00-23:59). The blue colours are the main European hours, starting at 8:00. The red colours are the main US hours, starting at 14:00.

The performance of a trader depends, among other things, on his capacity to spot the best moments to trade. A good tool, which visualises the time and the size of the volatility, is therefore crucial. Volatility changes over time. Many novice traders ignore this essential fact. When volatility drops in one market, good traders change to another market. Most strategies require a minimum degree of volatility in order to be successful. One rare exception to this rule is the MAD Rebound strategy, which appears to thrive in markets going sideways with limited volatility.


Example 1: the DAX CFD. Free platform demo

The volatility (HVH) of the DAX.

This HVH example shows the German DAX market index.The blue blocks correspond to the main European trading hours. The red blocks correspond to the main U.S. trading hours. It is clear that the DAX is at its most volatile in the second hour (9h00 to 10h00). In this example the volatility in the second hour was 0,48 %. After 10.00 o'clock the trader must be satisfied with less volatility (0,35% in this case).

Example 2: the DOW CFDFree platform demo

Hourly volatility of the DOW market index.

This HVH example shows the DOW market index. The two most volatile hours are the 15th hour (15h00-15h59) and the 16th hour (16h00-16h59). The hourly volatility during these hours is 0,38% en 0,43% respectively. When the DOW quotes, for example, 24 000 this implies that the DOW moves on average 103 points during the 16th hour. Notice that currently the DOW is more volatile than the DAX, with three hours during which the volatility exceeds 0,40%.

Example 3: Apple (AAPL). Free platform demo

Hourly volatility of Apple (AAPL) stock.

This HVH example shows the Apple stock (ticker AAPL). Apple does not trade 24 hours per day. Hence only eight blocks are shown. These blocks corresponds to the U.S. stock market hours. The first block is the 14th hour (14h00-14h59), which includes the pre-market.

CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 66% of retail investor accounts lose money when trading CFDs with this provider. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

Futures are complex instruments subject to unpredictable changes in price. They are financial instruments which offer the investor the possibility to use leverage. The use of leverage implies the risk of losing more than the total value of the account.
