The Bars object

Description

Williams' Ultimate Oscillator uses weighted sums of three oscillators, each using a different time period (7, 14, and 28), which represent short, medium, and long term market trends. The Ultimate Oscillator moves within the range of 0 to 100.

Interpretation

Williams recommended method of interpreting the Ultimate Oscillator is to look for divergences between the indicator value and price. For example, a bullish divergence occurs when prices make a lower low, but the Ultimate Oscillator fails to make a lower low.
