How to Use Standard Deviation Indicator in Trading
Author: Victor Gryazin
Dear Clients and Partners,
Today the article is devoted to the Standard Deviation indicator. It helps evaluate the dynamics of volatility of a financial instrument and find promising entry points.
What the indicator shows
Standard Deviation (STDev) is a trading instrument that shows how far the price of a financial instrument deviates from standard values of a certain period. It shows the deviation from a Simple Moving Average and thus helps to assess the change in the price volatility.
The indicator conditionally belongs to trend ones: when it grows, this might mean the beginning of a new market trend. The higher the volatility and the more the price fluctuates from the average over the chosen period, the higher STDev values will be. And vice versa: if the quotes are stable, trading in a narrow price range, indicator values will fall to the lows.
STDev can be used for trading on its own and alongside other indicators. Also, it is used inside more complicated indicators. For example, it can be found in a famous channel indicator Bollinger Bands: STDev helps to calculate the borders of the price range for the quotes.
Standard Deviation appears in a separate window under the chart and has just one main line. Its values start with 0 and always remain positive, i.e. never drop under 0.
The indicator does not show trend direction. The line will grow alongside the growth of volatility regardless of the market direction, equally when the quotes are growing and falling.
How to install Standard Deviation
Standard Deviation is built in the majority of popular trading platforms. To install it on the chosen price chart on the MetaTrader 4 and MetaTrader 5 platforms, go to the Main Menu. Your algorithm is: Main Menu – Insert – Indicators – Trend – Standard Deviation.
