Stretch / Squeeze
With the arrival of April (and oddly enough, April Fool's day), we move to the next portion of our
syllabus - Stretch / Squeeze.
What is Stretch / Squeeze (STR/SQU), and how does it work? Why does STR/SQU create a dangerous situation for those individuals who choose not to use it correctly? How does one calculate STR/SQU?
To understand STR/SQU, one must first understand how the futures and cash markets interact. In a general sense, STR/SQU seeks to provide a 'signal for change' based on
fair value in relation to the
premium. For Jack's explanation of STR/SQU, see
this post. For a detailed discussion from last year regarding STR/SQU, review
this discussion.
STR/SQU creates a dangerous situation for a trader who fails to use it correctly because doing so places the trader on the wrong side of the market. As I discussed in
this post, a trader on the
correct Resolution Level only monitors change at certain 'Action Points' throughout the trading day. Just as we have seen with all other tools, we also need to use STR/SQU
only at those same 'action points.' In other words, using STR/SQU at the
incorrect time can cause negative results.
To calculate the STR/SQU we use the following formula:
((YM07M -INDU) -'offset')
Several methods exist for calculating the 'offset' value. Some have chosen to use the 'premium' value from
indexarb.com, while others, choose to simply use the offset created by the difference between the YM and the INDU to 'zero out' the formula. In this fashion, one can chart the STR/SQU value over time (using a one minute chart of Histogram design). Mak has used a third method for STR/SQU comparing the ES to YM while adding some IF1IF2 logic for good measure.

Determining which method to use for each individual trader, best results by, determining which method works within a specific charting platform (or Excel).
For Qcharts users, Place the following formula (copy it exactly) into a quotesheet, and create a one minute chart of that formula (in Histogram Style). See attached screen capture.
((YM07M -INDU) -72)

Please, remember to recalculate the 'offset' value (at minimum) prior to the beginning of each market day. On occasion, one will need to recalculate the offset intra-day. When you see the STR/SQU values 'skewed' to one direction or another, you'll know it is time to recalculate.
I calculate the 'offset' value using the close of the 15:58 PM Eastern Time bar for the YM and the close of the INDU. I recalculate during periods of calm (e.g. CCC or no price movement), when noticing my histogram skewed away from the zero line.
In an environment where the futures lead the cash, we say STR/SQU provided a signal when we see levels exceed +2 (Stretch) or fall below -2 (Squeeze) on our chart. In other words, STR/SQU provides
both signals for
continuation and change. When STR/SQU falls within the -2 to 0 to +2 zone, we say STR/SQU sits at neutral.
By example, if a trader had just entered short, a 'Squeeze' signal (below -2) on STR/SQU provides
continuation. However, had the same trader entered long, the same 'Squeeze' signal (below -2) on STR/SQU, provides a signal for
change. Keep in mind, we use STR/SQU
only on our 'action points' as determined by our individual Resolution Level.
To monitor STR/SQU manually, feel free to use
this log file.
O.K. So where do we go from here? Spend some time monitoring STR/SQU through the day. Learn how it can provide two different signals within the
same bar during periods of
High Volatility. Note also, how such a fine level monitoring (Bug Level) currently sits
far beyond our current focus. Take some notes to 'see' how STR/SQU acts around FTT's, Point Threes and Spike Bars. In other words, spend some time learning this new tool
before working it into a regular position within your monitoring paradigm.
Lastly, If a trader has not yet spent the appropriate time monitoring the YM and the ES, or if a trader hasn't yet mastered PRV Volume, Price Channels and Gaussians, then one should
not add STR/SQU until completing the previously mentioned tasks - and practiced to an appropriate level of proficiency.
I hope you all find the above information useful.
