Co. (SWFT), I played the big W differently. I bought when price returned to the launch price, expecting a strong move higher as oil prices were trending downward: “Sell reason: The stock has made a large down move today, following the market lower and others in the industry [are] down. I believe this will move lower, forming a handle to the big W.”

      A handle did form, and I sold in the early part of that development at 19.25, for a loss of 8%. I watched from the sidelines as price climbed to 33.66. I missed out on a potential gain of 75%. Sigh.

      Again, I picked the right stock, but it took me out when it formed a handle before making a strong push higher.

      I don't have a lesson to share except the idea of riding price higher after it reaches the launch price might have merit. Test it to be sure it can work for you and your markets.

Sample Trade

      Figure 7.4 shows this chapter's sample trade with the big W located at AC. Before I discuss the trade, let's apply the measure rule to this pattern.

The measure rule uses the height of the big W. The peak (B) between the two bottoms has a high price of 12.66. The lower of the two bottoms is C, at 11.27, for a height of 12.66 – 11.27 or 1.39. Add the height to the price at the peak (C) and you get a target of 12.66 + 1.39 or 14.05. Price will reach the target 74% of the time in bull markets, according to Table 7.10. If you want a closer target, take half the height and use that. Thus, a closer target becomes 12.66 + 1.39/2, or 13.36. Price reaches the half‐height target 88% of the time.

Figure 7.4 John decided not to trade this big W because of overhead resistance.

      Want to know if the big W is tall? Take the height (1.39) and divide it by the breakout price (12.66) to get 1.39/12.66 × 100 or 11.0%. Table 7.5 says that a tall pattern needs to have a value above the median 11.9%, so this pattern is short. That suggests underperformance.

      The launch price is at H, where the downtrend begins. H could be a post‐breakout target, but as you can see, the stock didn't climb that far.

      Volume trends downward (G), so that's good for performance (from Table 7.6). It may be difficult to tell from the chart, but the left bottom has volume of 492 shares and the right bottom has volume of 791. In other words, the right has higher volume and that's good for performance (from Tables 7.10 and 7.11).

      The pattern is short (bad), volume trends downward (good), and the right bottom has higher volume than the left (good). This seems to suggest a better performing big W. Of the three measures, the height is the most important and it was bad. That's not a good omen.

      How did John trade the stock? “I didn't.”

      “Why not?”

      “I used your simulator to scan charts and didn't like what I saw. I looked for a horizontal move followed by a big W.”

      He was referring to my Patternz software (available for free on my website at www.ThePatternSite.com), which has a trading simulator built into it. It will advance to a chart pattern and then play back price at the speed of your choice.

      “I saw setup after setup which didn't work so I decided not to trade the stock. Sometimes the best trade you can make is none at all.”

      However, another setup is similar to this situation. Imagine the same setup with price forming a top, moving sideways (D), and dropping to a chart pattern (a big W or other type of chart pattern). Price does its thing, and the stock eventually climbs to close above H (the high point in the horizontal D move). That's the time to buy. I describe this setup at http://thepatternsite.com/CPSetup.html (Note: case is important).

      In Figure 7.4, price broke out upward from the big W (a close above B) the day before E. That confirmed the big W as a valid chart pattern. Then price stalled as if the bulls were afraid of attacking overhead resistance set up by the sideways move at D.

      The stock collapsed, and when price closed below the bottom of the big W, at F, it busted the upward breakout. The stock recovered to poke its head above 13, but moved lower to bottom at 8.11 in December. Had John bought at the breakout price and sold at the ultimate low, he would have lost 36%, not including commissions and fees. He made the right decision to walk away from this trade.

Broadening bottoms are middle‐of‐the‐road performers because the breakeven failure rate and average rise or decline are mediocre. I've traded this pattern only a handful of times over the years but made a profit 75% of the time. Even though performance needs improvement, maybe you can make money trading the pattern. Let's see
