How to interpret standard deviation?
Below are the primary ways of interpreting standard deviation as applied to the forex: 1 Low: Low levels of deviation indicate that price action is condensed and the market is in relative consolidation. In response, traders may choose to adopt rotational trading strategies, such as a reversion-to-the-mean approach. When adhering to this type of methodology, opposing positions are taken from the vicinity of a periodic extreme. Profitability is then sought from price returning to its relative average or mean value. 2 Normal: Normal deviation suggests that a market is behaving as expected, exclusive of any undue turbulence. A broad array of strategies may be warranted, including scalping, range trading, and pivot point methodologies. 3 High: High standard deviation readings suggest that pricing volatility is at extreme levels. This is accompanied by wide periodic ranges, robust price action, and heavy participation. Currency pairs that exhibit high volatility present traders with a quandry, as the enhanced price action increases both assumed risk and potential reward. Trend following and reversal strategies often become attractive due to the possibility of realising extraordinary gains.
