Awesome Oscillator (AO)

Awesome Oscillator - A histogram-style momentum indicator by Bill Williams. It is calculated as the difference between a 5-period SMA and a 34-period SMA of the median price. AO oscillates around zero (unbounded scale). In trading bots, common signals include AO crossing above/below zero or chart patterns (e.g. twin peaks, saucers) to confirm momentum shifts. MQL4 has the iAO() function; in cAlgo use Indicators.AwesomeOscillator(). AO helps confirm trend direction and momentum in automated strategies.
