The AC indicator measures acceleration and deceleration of these forces. If indicator rises it means that market is inbalanced now and buy power is greater than sell one and vice versa.

Formula

MEDIAN PRICE = (HIGH + LOW) / 2 AO = SMA (MEDIAN PRICE, 5) - SMA (MEDIAN PRICE, 34) AC = AO - SMA (AO, 5)

Where: MEDIAN PRICE — median price; HIGH — the highest price of the bar; LOW — the lowest price of the bar; SMA — Simple Moving Average; AO — Awesome Oscillator.

Most useful cases

• Divergence/Convergence - Divergence/Convergence pattern is a form of price action when new high(low) of the price not confirmed with a new high/low of AC. Such price and indicator’s behavior can be interpreted as the weakness of current existing trend.

• Crossing zero line - this is a trend reversing signal and it can be very useful in case of determining a correction of existing trend, beginning of a new trend wave or starting a new trend.
