# Awesome Oscillator (AO)

The Awesome Oscillator (AO) indicator shows the direction of the market’s driving force. It’s the difference between the 5 period and 34 period simple moving averages of the median price. The AO is plotted using the current median price as the nought line.

• When a saucer appears entirely above the nought line
• When the oscillator crosses the nought line from below and becomes positive
• When two pikes appear entirely below the nought line
Saucers and two pikes are defined as follows:
• A saucer is a three interval pattern where the middle interval is the lowest of the three
• Two pikes is a deep minimum followed by a shallower minimum – all the intervening intervals must be below the nought line
The sell signals are the opposites of the buy signals:
• When a saucer appears entirely below the nought line
• When the oscillator crosses the nought line from above and becomes negative
• When two pikes appear entirely above the nought line
Saucers and two pikes are inverted for sell signals:
• A saucer is a three interval pattern where the middle interval is the highest of the three
• Two pikes is a maximum followed by a lesser maximum – all the intervening intervals must be above the nought line

#### Calculation

The Awesome Oscillator is the 5 period simple moving average (SMA) of the median price, minus the 34 period simple moving average. This is plotted using the current median price as the nought line; the current median price is subtracted from the oscillator.

AO( J ) = SMA( MEDIAN( J ), 5 ) – SMA( MEDIAN( J ), 34 )

MEDIAN = ( HIGH( J ) + LOW( J ) ) / 2

PLOT = AO( J ) – MEDIAN( J )

J is the current interval
