Probability Grid
By LuxAlgoApr 9, 2025

The Probability Grid tool provides traders with a visual representation of where and when the next market reversal might occur. By leveraging a 10x10 grid or an informative dashboard, it predicts the probability of price reversals, offering traders valuable insights for better decision-making.
How to Use the Probability Grid Effectively?
The Probability Grid displays deciles, or percentiles from 0 to 90, by default. Users have the flexibility to enable, disable, and modify each percentile according to their needs, but at least two must always be enabled to prevent error alerts. This tool assesses the market accurately; the further the price travels on the grid, the higher the probability of a market reversal. In illustrated scenarios like the one above, a reversal is seen in a cell with a calculated 9% probability, which indicates a 91% chance within the square defined by the previous reversal and this specific cell.
Grid vs Dashboard: Which One to Use?
This tool can present information through a grid originating from the last reversal, or a dashboard positioned in one of three predefined locations, as illustrated above. Both options provide traders with clarity on potential reversal points.
Key Features of the Probability Grid
Raw Data vs Normalized Data
The Probability Grid tool defaults to displaying normalized data, where it utilizes returns between reversals rather than raw data (or price deltas). This approach ensures a consistent and fair comparison across the dataset. On the left side of the BTCUSD Daily chart above, with normalized data disabled, percentiles from 0 to 40 are indistinct due to raw historical price deltas. Conversely, with normalization active on the right side, data comparisons remain valid throughout history.
Understanding Probability Metrics
This tool offers two probability modes - default being Probability Beyond Each Cell. It shows the chance of a reversal beyond each respective cell. For instance, a cell marked with 20% indicates a high 80% probability of a reversal occurring within the square starting from the last known reversal to this cell, leaving 20% outside it. Alternatively, users can switch to a mode focusing on the probability within each cell, offering a more micro perspective with equal chances (1%) across the entire 10x10 grid when set to default deciles.
