How a Professional Daytrader Watches Patterns
09/03/2010 12:01 am EST
I tend to write from a more theoretical perspective in these blogs, but today’s market action provides a few interesting lessons. By way of background, I have not been happy with my trading performance over the past few months. I am just not achieving the level of consistency in my intraday trading that I know is possible. In response to the frustration I have been feeling, I have scaled back both the size and scope of my trading and am now focusing on the broad market by only trading a few hundred shares of SPY at a time. (This is also a return to my days when I traded S&P futures exclusively. In this post, I will speak in S&P futures points, where each ES point = .10 in SPY.) My focus over the past several weeks has been working to refine my practical application of the interaction of smaller and larger time frame patterns, but always using the patterns to get to an understanding of the relative balance of power of the buyers versus the sellers.
(I started writing this to illustrate one simple pattern, but as I’m writing, I find myself mentioning quite a few other patterns that are also important. Technical trading is never as simple as “See this pattern, then buy,” but it’s more about seeing evolving market structure to try to understand how the relative balance of buyers and sellers is playing out. I will denote the smaller patterns within the pattern with numbers in parentheses, just to highlight what I think are the important, relevant, and repeatable patterns that make up the total picture.)
The big gap up on the open is a welcomed sight in late summer, because it sets up a high probability for a directional day (1). Finally! I know most true gaps (today’s open outside of yesterday’s range) tend to fail (2), and at least fill a significant percentage of the range, if not all. However, I also know that bigger picture, the (cash S&P) market has tested support at 1,040 three times over the past two weeks, with good price rejection at the level, we put in what looks like a significant higher low on the hourlies, and there was some strange buying after the close. In addition, I know what happened overnight with economic releases from Asia, but more importantly, I saw the price action in those broad equity indexes overseas. My bias is strongly up for the day, but there’s too much potential for a five-to-eight point flush on the open to ignore that possibility, so I have to trade what I see as the price action evolves.
I actually shorted the new lows about ten minutes into the day, but was very aware that a standard pattern is to drop the lows, trap some bears, and then go screaming to new highs (3) early in the day. You have to take the short because there is too much good downside potential, but you have to realize it is probably a trap, so it puts you in an interesting state of mind. I also know of potentially significant (in retrospect, that turns out to be a humorous understatement) reports at 10AM today, so I will not be holding my full size into those reports regardless.
The short was short-lived. Flipped long a point and a half above my entry a few minutes later as the market held the lows and took out some swing points to the upside (4). Nice little ding to start the day, and of course the potential for being round-tripped now, but you have to do the right thing regardless of how you feel about it. Sold enough of my longs into the rally to be very small in front of the number.
Now we get the real fun: A huge rally off the number—ten-plus S&P points in a single five-minute bar. I know two things. First, this is unsustainable behavior so it is probably some kind of buying climax (5), but anyone thinking short after what has just happened is a complete idiot. I will hold my small remaining long until I see clear reason to get out, and then will reestablish lower. I also know that a giant climax after a gap up like this can easily leave us range-bound in a tight range for most of the rest of the day (6), but I know there’s a very good statistical edge for that range to resolve the upside (7), if not today, then tomorrow morning. I also know that, even though people like to think about measured moves, the probability of having a clean measured move off of a climax bar like this is rather small (8), so I will have to be happy with a smaller upside target. I make a mental note to only short today if I see clear and sharp downside momentum (which never happened).
Now we get the reason I originally started writing this article. A very common trend-ending pattern occurs when a market makes three symmetrical pushes (on any time frame). Depending on how extended the trend is, you may start thinking countertrend, but at least you must be very, very careful about holding with-trend positions through this pattern. The pattern grows out of the standard ABC wave, which itself is a continuation off of a strong impulse move. When you see the three pushes, it just means that the normal trend leg has reached its expected target. This is a good warning to not press with-trend positions. Schematically, the pattern looks like this:

As I was holding my long position, I saw the S&P market make three symmetrical pushes to new highs (9), the last of which came at noon, which, as we know, is a common inflection point (10). I was quick to get flat after the inside bar following the third push resolved to the downside (11).
“Three pushes to end a trend” is a form of buying climax. I know that there is a chance that this is an actual end of trend, which may be followed by a reversal (12), but I also know that I will have to see real weakness before even thinking short (12a?). For now, the highest-probability play is a substantial pullback to work off the overbought condition, and at least a retest of the highs later in the day (13). I re-establish my long position at the 20-period EMA, which simply provides a reference for a point of relative balance in an overextended market (14).
After a very sharp move, the first pullback to the moving average is always worth a shot. In addition, we see a “ragged bottom,” which is a sign of classic Wyckoff-type accumulation (15). Intuition says you would rather buy a clean test of support, but intuition is wrong in this case. Every little test below support was immediately met by buying pressure. We rallied a bit off that support, so the first pullback is another good spot to add to your position (16).
So now I’m feeling pretty good about myself, and am positioned fully long (OK, fully long and then some) as the market is pressing against new highs at 2 pm. Considering the structure of the day has been a very sharp up move, a long sideways consolidation with good accumulation, I know there is a very high probability of another leg up in the afternoon, and probably closing on the highs (17). In addition, I see the market pressing against new highs at 2 pm, which we know is the ideal time for a breakout (18). I use this as justification to be overloaded on my long position (mistake #1).

I realize that the Russell is rallying harder than the S&P, which you can see on the chart below by noticing that the Russell is lifting farther off the EMA than the S&P on rallies (19). If there was any doubt about which was stronger, the Russell makes three attempts to take out the high of the day while the S&P is holding well under. This is a form of divergence. We want to see all indexes taking out the highs at the same time for the highest probability of a good rally. If we see divergence, it significantly reduces our confidence in the rally (20). In addition, I can see clearly on my one-minute chart of the Russell that the Russell just made three pushes to new highs (you might call it some variation of a triple top), and failed fairly dramatically. This is bad, bad, bad for long positions (21), but I decide to hold my larger-than-full-size position a bit, just to give it a little more room. (This is mistake #2, and you don’t need three to do damage.)
The blue line in the chart below is high of the day for both indexes. Notice how clear this pattern is, but I ignored what I knew was a very high-probability pattern. This is fighting the market, and it is pretty stupid, and the way to really do it right is to do it on a larger-than-full-size position! Ugh. I took a nasty ding out of what had been a pretty good day up to that point. The market is pretty efficient in punishing mistakes and stupidity. Of course, the right thing to do was to have sold at least the extra size at the first sign of weakness, get very small on the third-push failure, and to have at least taken the rest off at breakeven.
The day eventually did break to new highs, which is an important reminder that these trend-ending patterns do not mean the trend is going to reverse. I did not repeat my mistake and ended the day with a decent profit for the size I’m trading, but easily gave half my day away with one stupid mistake: trading against a high-probability pattern.
