The bars

The ultimate oscillator

The ultimate oscillator is 62.9, between 30 and 70.

The three windows: Buying pressure took 65% of the range over 7 bars, 63% over 14 and 55% over 28. Buyers closed the bars nearer their highs; the short window counts 4 times, the medium twice.
How it is read: Williams' own buy signal was a bullish divergence below 30 (a lower low in price, a higher low in the oscillator) followed by a break above the high between them; the sell signal mirrors it above 70.
Read it with care: Without the divergence, a reading above 70 or below 30 can last a long time in a trend.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Three speeds in one line

Larry Williams built the ultimate oscillator in 1976 to fix a flaw of one-window oscillators: they flip too fast or too slow. For each bar it measures buying pressure, the close minus the lower of the low and the previous close, and the true range. It adds both up over 7, 14 and 28 bars, divides, and blends the three ratios with weights 4, 2 and 1.

Compare it with the stochastic calculator and the Williams %R calculator, and size the trade with the position size calculator.
