● A “double three” combination comprise two corrective patterns separated by one corrective patternin the opposite direction, labeled Ⓧ. The first corrective pattern is labeled Ⓦ, the second Ⓨ. ● A "double three" combination comprises (in order) a and a flat, a flat and a , a flat and a flat, a and a or a flat and a . ● Wave Ⓧ appears as a zigzag or flat. (TWEWA) ● Wave Ⓧ always retraces at least 90 percent of wave Ⓦ. ● Combinations have a sideways look. With respect to waves Ⓦ and Ⓨ in a double three, only one of those waves in each type of combination appears as a . ● Combinations can occur in the same wave positions as flats and triangles (except for the triangle subwave) but cannot occur in waves Ⓦ and Ⓨ.
❗ Guidelines:
● Wave Ⓧ is often 123.6-138.2% the Ⓦ wavelength, less often wave Ⓧ retraces 161.8% or more. Don't expect wave Ⓧ to be more than 261.8% of wave Ⓦ. (TWEWA) ● Wave Ⓧ is usually a single or multiple zigzag. ● When a zigzag or flat appears too small to be the entire wave with respect to the preceding wave (or, if it is to be wave ④, the preceding wave ②), a combination is likely.
☝ Notes:
● An expanding triangle has yet to be observed as a component of a combination.
