Using Standard Deviation but not sure if the Standard Deviation is high or low?  eRSD or Easy Relative Standard Deviation comes to your help. Using this you can get a ratio of Standard Deviation to Moving Average and make a good judgement about whether the Standard Deviation is useful or not. Just add it to the chart and use it away - it supports all periods and moving average calculation methods through the input parameters.
