The vertical horizontal filter over 28 bars is 0.55, above 0.53, the level a pure random walk stays under on 19 bars in 20: the closes have gone one way more than chance usually gives, a trending stretch.
The close, the highest minus the lowest close over the look-back, and the 28-bar VHF on the last bars. The last bar is marked.

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.

Adam White's vertical horizontal filter takes the highest close minus the lowest over the look-back and divides it by the sum of the sizes of every bar-to-bar move in between. If the closes went straight one way the two are equal and the VHF is 1; the more they went back and forth, the closer it falls to 0. White used it to choose between trend tools and range tools. Fixed lines are hard to set, since the usual reading depends on the look-back, so the page compares yours with a simulated random walk of the same length.
Ask the same question with the choppiness index, the ADX calculator and the random walk index.
