I am willing to calculate and monitor the evolution of extreme-viscosity in the financial markets data series.
Wikipedia says "Put simply, the less viscous the fluid is, the greater its ease of movement ". So rather than looking for the mighty viscosity should I simply focus on ease-of-movement? Well, the "ease of movement - (EOM)" is a catchy phrase since there is a well known indicator with the exact same name. That EOM indicator is defined in investopedia as: "A technical momentum indicator that is used to illustrate the relationship between the rate of an asset's price change and its volume. This indicator attempts to identify the amount of volume required to move prices."
In elementary school mathematics it is as simple as: EOM = (Close of today - Close of yesterday) / Volume
Do think "extreme viscosity can be monitored by the extremes in EOM"... Or would you suggest something else to calculate viscosity?
