Can you explain the coincidence error?  I thought the projection was based on the full population and not a sample.

The coincidence error (or matching error) is standard deviation (in points) between Open, High, Low, Close prices of all bars in a pattern found in the bars history of the current symbol and the same in the current pattern (last PatternLength bars).

@FX-Philosopher,

the indicator show one, two or three identified "best" patterns with least errors of coincidence.
