chart formation mathematical expectation

i was wondering if there have been any studies on the mathematical expectation and probabilities of common chart formations. (i.e. head and shoulders, double bottom, double top, triangles)

i realize that recognizing them is very discretionary, and subjective, but i still want to know.

if anyone has a link or any numbers it would be appreciated

Have a look at this:

- "The performance analysis of chart patterns: Monte Carlo simulation and evidence from the euro/dollar foreign exchange market"

To get the information is like asking a blind man directions....it's not an
information bureau, it's an obstacle course inside a fake brothel.

There are several (older) reports from the NY Fed you might find of interest:

very good links, thank you

But there's some great information there! (although the stats may apply to equities rather than forex). Probabilities of 104 candle patterns and 76 chart patterns, summarized from the best seller Encyclopedia of Chart Patterns by Thomas Bulkowski:
