Probability Grid

By LuxAlgoApr 9, 2025

Probability Grid turns the question of when a move ends into measured odds. It profiles the distribution of returns between past reversals, slices that history into percentiles, and projects a 10x10 grid forward from the last confirmed reversal. The further price travels across the grid, the higher the calculated odds that the move ends there. Percentile rows from 0 to 90 display by default, and each can be enabled, disabled, or adjusted, with at least two always active.

How to Trade the Probability Grid?

  • Price deep in the grid: in the default Probability Beyond Each Cell mode, a cell marked 9% implies a 91% chance that the reversal lands inside the square anchored at the previous reversal, a stretched move.
  • Probability Within Each Cell: the alternative mode reads odds cell by cell; at default deciles every cell starts near 1%.
  • Dashboard mode: the same statistics condensed into a panel in one of three preset locations, for traders who want the numbers without the overlay.

Normalization keeps the math fair: by default the tool works on returns between reversals rather than raw price deltas, so old history stays comparable with recent action. It sits alongside LuxAlgo's other statistics tools as a probability-first way to frame exhaustion.

Probability Grid Settings

  • Swing Length: maximum bar length for swing recognition, the reversals that seed the dataset.
  • Maximum Reversals: caps how many past reversals feed the calculation.
  • Normalize Data: toggle between swing returns (default) and raw price data.
  • Probability: choose odds beyond each cell (default) or within each cell.
  • Percentiles: enable, disable, or restyle each percentile row.
  • Dashboard and styling: dashboard visibility, position, and size, plus grid visibility, text size, colors, and reversal marks.
