Historical Stock Pattern Analysis

Start with the completed window

Select the start and end of the movement you want to research. Historical search compares that query with completed past windows, so a later outcome is available for every returned match.

This is different from looking at one chart in isolation: you can inspect a group of comparable cases and the range of what followed.

Read the distribution, not one example

A single excellent match is memorable but statistically fragile. Review the number of matches, where they occurred, their quality, the median result, and the full spread of positive and negative outcomes. A wide spread is a useful finding: the visible shape alone did not determine what happened next.

Avoid hindsight bias

Define the selected date range, timeframe, and threshold before reviewing results. Repeatedly adjusting a query until it creates an attractive historical story is not the same as testing a reusable research method.
