The closes

The McGinley Dynamic

The 14-bar McGinley Dynamic is 2,355.01; the last close, 2,443.60, is 88.59 (3.76%) above it.

The direction: It was 2,349.25 on the bar before, so it is rising. The close last crossed above the McGinley line 20 bars ago.
Against the EMA: The 14-bar EMA is 2,393.82: the EMA is closer to the close. In these bars the close crossed the McGinley line 8 times and the EMA 8 times. Both lines were crossed the same number of times.
Read it with care: It is an average of past closes, so it follows the price rather than leading it. Its speed changes with the gap between the close and the line, so its readings differ from an EMA's even with the same number of bars.

An average that sets its own speed

John McGinley designed the Dynamic to adjust its speed to the market instead of moving at a fixed pace. Each bar it moves part of the way toward the close, and the size of that step depends on the ratio of the close to the line, raised to the 4th power. When the close runs above the line the step shrinks, so the line follows a rise with care; when the close falls below it the step grows, so the line drops faster. The page keeps each step no bigger than the gap, so a sudden fall cannot throw the line past the price. The other side of that care: in a steady rise it can lag well behind an EMA of the same length. The answer above compares the two on your bars.

Compare it with other averages in the moving average calculator, the adaptive moving average and the Hull moving average.
