3 Bar Patterns | The Smallest Fractals of Market Structure

"Any time there is a daily low with higher lows on both sides of it, that low will be a short-term low. We know this because a study of market action will show that prices descended in the low day, then failed to make a new low, and thus turned up, marking that ultimate low as a short-term point. A short-term market high is just the opposite. Here we will see a high with lower highs on both sides of it. What this says is that prices rallied up to the zenith of that middle day, then began to move back down, and in the process formed a short-term high. For our purposes in identifying short-term swing points, we will simply ignore inside days and the possible short-term points they produce." This is how Larry Williams defined market structure. His concept is universal and applies to all bars of all time frames.

• A Short-Term High (STH) is a bar with a high greater than or equal to the high of the bar to the left and greater than the bar high to the right. Neighboring bars should not be inside. If they are inside bars, the bars that follow them should be analyzed.
• A Medium-Term High (MTH) has Short-Term Highs to the left and and to the right that are below the high of this bar.
• A Long-Term High (LTH) has Medium-Term Highs to the left and and to the right that are below the high of this bar.
  

And for the lows it’s all vice versa: 

• Short-Term Low (STL) = bar with higher lows on both sides
• Intermediate-Term Low (ITL) = higher STL on both sides
• Long-Term Low (LTL) = higher ITL on both sides

In other words: 3 bar patterns are the smallest fractals and building blocks of market structure. Since price is always either in consolidation, in an uptrend or in a downtrend 3 successive price bars must form either a directional pattern (higher highs, higher lows or vice versa), a continuation pattern (inside bar) or a reversal pattern (outside bar, pin bar, head & shoulder, M&W patterns) (see also HERE):

In Any Bar Chart Only 8 Possible Range Patterns | Larry Williams

Larry Williams presented a free session at the November 2014 Las Vegas Traders Expo in which he discussed 8 possible Range Patterns. He showed that from any bar to the next there are only 4 possible outcomes:

1. Down Range: Last Bar's high is lower than prior Bar's high; and last Bar's low is lower than prior Bar's low.
2. Up Range: Last Bar's high is higher than prior Bar's high; and last Bar's low is higher than prior Bar's low.
3. Inside Range: Last Bar's high is lower than prior Bar's high; and last Bar's low is higher than prior Bar's low. On a Daily S&P500 Chart this occurs approximately 12% of the time.
4. Outside Range: Last Bar's high is higher than the prior Bar's high; and Bar's low is lower than the prior Bar's low. On a Daily S&P500 Chart this occurs approximately 12% of the time.
   

Price action cannot occur in any other way. Within these 4 Range Patterns each last bar can either be an up bar or a down bar. So there are actually 8 possible Range Patterns:

1. Down Range, Down Day
2. Down Range, Up Day
3. Up Range, Down Day
4. Up Range, Up Day
5. Inside Range, Down Day
6. Inside Range, Up Day
7. Outside Range, Down Day
8. Outside Range, Up Day

Using these 8 patterns some powerful strategies can be created. Larry Williams presented back-tested statistics associated with trading these patterns using a simple entry and exit technique. He stressed that they were not the best entry or exit techniques but shown because they were easy to understand and program. This strategy is intended only to show where we have a bias or advantage in the marketplace.

• Entry: At market close
• Stop Loss: Based on $ Stop
• Exit: First Profitable Opening

His message was that we could go home and verify using our own software. His results for testing this on the e-mini S&Ps from 2002 forward [to 2015] were as follows:

So, the Down Range, Down Close day [1.] offers the best potential short term 'long' setup based on net profit. This was the take-home message of the presentation.

Larry further dug into the Down Range, Down Close setup to uncover which day of the week offered the best trade: The stats support the 'Turnaround Tuesday' concept.

And further investigating by Trading Day of Month revealed that 1, 17, 19, 22 and 23 were the best days, showing 92% winners and $47,500 net profits with 107 trades.

It was also found that a Down Range Larger Range day was better than a Down Range smaller Range day. $205 Avg 80% Win, vs $33 Avg 85% win,

Also naked close was better than a covered close (naked close meaning that the close was outside of the previous day’s range). $155 Avg 83% Win vs $30 Avg 83% Win

And combining these two concepts:
Down Range, larger range, Covered close: $60 Avg, 83% Winners
Down Range, larger range, Naked close: $215 Avg, 85% Winners
