WhenWasThePriceAction

Bars of largest range (volatility)

* see moments of strongest price action immediately
* colored & upDown by candle color
* amplifier: you see only the bull runs, and subsequent dumps

Very nice on the 5 years scale of BITSTAMP:BTCUSD - nothing comparable to 2013 has happened yet.

Internals:
squared_range = pow(high-low, 2)

That is essentially it already. The rest are details:
* gauge with (in case of Bitcoin exponentially rising) price
* show in red for negative candles
* take even higher polynomial (than 2) to show only the very largest values
* allow some user input (but there is not much more that can be chosen here.)

Sorry for such a simple formula - but sometimes the easiest things are powerful.
