Awesome Oscillator.

Awesome Oscillator Technical Indicator (AO) is a 34-period simple moving average, plotted through the middle points of the bars (H+L)/2, which is subtracted from the 5-period simple moving average, built across the central points of the bars (H+L)/2. It shows us quite clearly what’s happening to the market driving force at the present moment.

AO signals to buy:

* "Saucer" is the signal to buy which appears when the direction changes from the downward to upward with the second column is lower than the first one and is colored red and the third column is higher than the second and is colored green. It is generated when the bar chart is higher than the nought line.

* "Nought line crossing" is a signal to buy which appears when the bar chart passes from the negative values to that of positive. Two columns are necessary for it: one of them has to be below the nought line while another has to cross it.

* "Two tops" signal is generated when the bar chart values are below the nought line and when a top pointing down is followed by another one which is higher thus closer to the nought line. If the bar chart crosses the nought line in the area between the tops, the signal to buy is not generated. If an additional higher top is formed and the bar chart has not crossed the nought line, an additional signal to buy will appear.

Calculation:

Awesome Oscillator bar graph is a difference between 5-periods simple moving average, built on central points of the bar (H+L)/2 and 34-periods simple moving average built on central points of the bar (H+L)/2.
MEDIAN PRICE = (HIGH + LOW) / 2 AO = SMA (MEDIAN PRICE, 5) - SMA (MEDIAN PRICE, 34)

Where:

MEDIAN PRICE - median price;
HIGH - maximum bar price;
LOW - minimum bar price;
SMA - simple moving average.
