A big W is nothing more than a double bottom with a tall left side. It might have a tall right side, too, but that depends on how well the stock performs after an upward breakout. If price doesn't break out upward, then it's not a big W. I'll discuss identification guidelines later.

The above Results Snapshot shows important performance numbers for the big W. For example, the breakeven failure rate, at 9%, is quite good (meaning relatively small compared to other chart pattern types). The average rise for perfect trades is 46% (bull market), which is also good, hence the rank of 11 where 1 is best. Bear markets see price climb by 30%, which ranks 8 out of 20, where 1 is best.

If you use the full height of the pattern in the measure rule computation, price will reach the target 55% to 74% of the time (bear, bull markets, respectively).

Let's look at examples of big Ws.
