      Height and width combinations. Patterns that are tall and wide outperform the other combinations of height and width. You might want to avoid short patterns (either narrow or wide). They underperform in bull markets and don't do that well in bear markets.

      Table 7.6 shows volume statistics for the big W pattern.

      Volume trend. Volume trends downward most of the time, as measured using linear regression between (and including) the two bottoms of the big W. As I mentioned, don't discard a big W because it has an unusual volume trend. Remember, the trend is your friend.

      Breakout day volume. Bull markets don't see a performance difference, but bear markets do with heavy breakout volume helping performance. The difference seems unusually wide, though, so additional samples will likely narrow the spread.

      Table 7.7 is one of my favorite tables because this kind of trading information can pay for the price of this book.

      How often are stops hit? I placed a stop‐loss order at the peak between the two bottoms and price touched this (after the breakout and on the way to the ultimate high) over 70% of the time. Scoot the stop a bit lower (the middle of the big W, measured from the peak to lowest valley) and the stop triggers less often, between 13% and 20% of the time. Place it at the lower of the two bottoms and it'll hardly trigger at all.

      The safe place to locate a stop‐loss order is below the bottom of the big W, but the distance between the stop and the buy price may entail a large potential loss. The rumors are true: Positioning a stop is an art you need to master to become a successful trader.

      Once you decide where to place the stop, convert the potential loss into a percentage of the current price. If you gasp at the result, then the stop is too far below the current price. Either adjust the stop location, abandon the trade altogether, or hope the trade succeeds.

      Table 7.8 shows how big W performance has changed over three decades. Because bear markets only occurred in the 2000s, they were excluded from consideration.

Description Bull Market Bear Market
Pattern top 73% 75%
Middle 20% 13%
Pattern bottom 2% 1%
Description Bull Market
1990s 42%
2000s 51%
2010s 45%
Performance (above), Failures (below)
1990s 8%
2000s 8%
2010s 11%

      Failures over time. I would expect to see low failure rates in the 2000s because that was the best performing decade, and yet the table shows it's tied at 8% with the 1990s. The 2010s showed a slight uptick in failures. The failures I'm reporting on, by the way, are 5% failures. They count how many big Ws fail to see price rise more than 5% after the breakout.

      Table 7.9 shows statistics related to busted patterns.

      Busted patterns count. Big Ws rarely bust, as the table shows (compared to other patterns, which see busts in the 40% range). What does this mean? Up to 20% of the time, on average, price will fail to rise more than 10% after the breakout before reversing and closing below the bottom of the big W. So if you want to make a lot of money, then one in five
