Specifics of Standard Deviation Indicator: Inversely, when the indicator's value is too high or even extreme, traders' activity will slow down soon. If the indicator's value is relatively small, the market is bored and a price spike should be expected. Since it measures price deviations from the average value in both directions, this tool is also used in channel indicators. The higher volatility, the stronger the trend is. The Standard Deviation is a trend indicator: it serves to identify the moments of trend strengthening. Volatility is measured by the Standard Deviation (StdDev) indicator. The more the price deviates from its average value, the higher the volatility. In trading, the arithmetical mean is a simple moving average. This variation of prices is called "volatility". The price ranges are different even if their averages are the same. Let's take two numerical sequences as an example:Ĭan we say they are identical as the SMAs are equal to 7 in both cases? No, we can't. Its disadvantage is that it doesn't consider price volatility inside a price range. The SMA is a technical analysis indicator calculated as the average of chosen prices. These values are relative and depend on a currency pair. If the price changes by 10%, volatility is high. If the change range doesn't exceed 3%, volatility is low. Volatility can also be measured relative to the moving average: the higher the price, the higher volatility.Īnother method suggests comparing the current price change in % with the previous period's closing price. These values can be found in the calculator on the site of Investing, for example. For example, 1-day volatility on a daily time frame is the distance between High and Low prices expressed in points. There are different ways of measuring volatility. Take Profit orders can be placed in the same way. If market volatility is moving in both ways, at which distance from an open trade should we place a stop loss so that the price line doesn't touch it? - According to larger time frames’ mean volatility. The extremums are visually compared with similar extremums over the previous periods. If volatility reaches its peak, the trend is about to end. For identifying a trend’s end and an eventual reversal.The growth of volatility means that a big price move emerged. If the price doesn't deviate from its average value, it's impossible to open a trade. If there is no volatility, there is no trading. In trading, it is used in the following ways: Volatility means a price change range over a certain time period. In statistics, it's denoted by the Greek letter (σ), or sigma.īefore examining the Standard deviation indicator, let's recall why a trader should consider volatility and what SMA means. The standard deviation is an indicator of the data average deviation value compared with their mean value over a chosen period. Trading borrowed the idea of standard deviation from descriptive statistics, which is a branch of mathematical analysis. Trading strategies combined with Standard Deviation Indicator.

The article covers the following subjects: Read on to find out how it works and how it is used in trend strategies combined with other indicators. How do we determine current volatility and trend strength? At which distance from the price mean value and market entry point should we place a stop loss? Is the market flat at the moment? The Standard deviation indicator can answer all those questions.
