Ron McEwan's Volatility Switch from February 2013 Traders' Tips (Stocks & Commodities magazine) is a simple, intuitive yet seemingly effective new indicator whose purpose is to act as a filter in a trading strategy, facilitating it to adapt to changing market conditions. A change from a trending mode to a mean reverting one is measured through a ratio dividing the number of bars when the Historical Volatility (HV) of the daily close price change in a given lookback period was lower or equal to today's daily ROC's HV.
