in a discussion on a bg forum somebody
was asking why no bot offers an indicator
of the volotility of a position (factor
that helps understanding cube decisions).
An answer stated that cubeful equities
already integrate the notion and are all
it is needed to take a cube decision.
All true, but an indicator of the volatility
will help the user understanding the
cube decision (i.e. understanding why the
cubeful equities are what they are).
Roughly (cubelessly) speaking, if the
equity of the current position is the weighted
average of the equities of the subsequent
postions in the game tree, wouldn't the
variance of such equities be an indicator
of the volatility ?
