YMU1, (3, -1),

Hi,
Bright, brief and gone...
27 June: (3, -1)...
11881 - 59 = 11822 (11818 = low print at 15:48PDT)
11822 + 59 + 59 + 59 = 11999 (12031 = high print at 11:40PDT).
This is the (3, -1) formula as applied to intra-day trading the September e-mini $5 Dow futures price range

28 June: (3, -1)...
11990 - 36 = 11954 (40 = Stretch... prices reversed at this low)
36 = the price range from unchanged to the low of the day, 11954.
11954 + 60 + 60 + 60 = 12134 (12144 = high)
60 = 1.618% of the Stretch

29 June: The (3, -1) strategy didn't repeat like Monday and Tuesday, but the move > triple 1.618% of the Stretch pattern did print the price point reversals +74, -70, +69, -107, -59. 69 points = 1.618% of the Stretch calculation for 29 June; and the low (the -107 point price swing), 12107, occurred at 07:06PDT, the first hour.

In months past these type of patterns, i.e., the (3, -1) formula and price reversals occurring at 1.618% and 2.618% of the Stretch have repeated, often, not always; but often enough to warrant a look at the tradeable probabilities of these price projection strategies.
