Previously, we looked at tools and indicators based around trend and momentum that confirmed price action. In this article, we will look at three further types of price confirmation tool: Volatility, Volume & Sentiment. These tools could help give you supportive, independent information in your analysis of any given asset. What is presented here, is not an exhaustive list of the technical tools used in this space, but some of the more generic and popular ones.


Volume is a measure of how much an asset has been traded in a given period of time. It can be a very useful tool to help confirm your price analysis. There are many volume tools, and we have already come across some in previous articles. For example, McLellan, Chailin and Accumulation / Distribution.

Like with volume, our paths have already crossed various volatility indicators such as Bollinger Bands and ATR. There are also very obvious measures that can be derived from price, such as historical volatility based on standard deviation. Another popular indicator used is the Chaikin Volatility measure. Appreciating the volatility of an instrument, can be crucial for your trade and risk management and an understanding of how the asset you are analysing behaves.

Example using the Standard Deviation tool for Amazon Inc (AMZN) to measure price action with a set up of 2 standard deviations on 14 daily periods (Charts: Stockopedia)



Sentiment is another area that you might want to look at adding to your technical analysis; often independently configured away from…
