  Subject: [RT] Toby Crabel ORB
  With the price of Toby Crabel's book being out of range and 
  unavailable atany price, I dug through all TASC articles he wrote and did 
  someexperimenting this weekend.  Remember the book and articles were 
  writtenback in 1988 and following years.  The opening range breakout 
  starts withusing the "stretch", a ten day average of some opening period 
  such as 5 orten minutes, and further refined to use inside bars and narrow 
  range days toselect days that preceeded trend days.  I believe the 
  concept needs somereadjustment with the advent of computerization and 
  electronic trading,globex, and speed of markets.  After concluding 
  that the original ORB"Stretch" value needed some updating, the next thing 
  was to figure out howto view that early day action.  At the same time 
  Toby was writing his book,Steidlmayer was introducing his market profile 
  ideas.  Of course Gann's ideaof midpoints or 50% retraces and eighths 
  had been around.  So without goinginto more details, here are some 
  shots of this morning's snp on 1 tick barsusing 30 minute mp and the poor 
  man's profile of midpoint and 1/3, 2/3divisions of the current day's high 
  and low.  Over the years, I have come torespect the realtime midpoint 
  of today's high minus low divided by 2, thered line on the chart.  
  Without further statiscal proof, my intuitive feelis that the ORB using 
  ten day Stretch average is better replaced withsomething like a market 
  profile using tick bars.  Using a combination ofmidpoint, point of 
  control and value area levels might be good
