Came across some online write up on Elliott Wave corrective structure guideline saying that the 5-wave in Wave A and C of the correction phase can be either an impulse or diagonal pattern (refer here).  On the other hand, the "official" Elliott Wave principle (Elliott Wave Principle -- Frost and Prechter) does not mention of such a guideline.  With that guideline and revisit the analysis on ThaiBev, interesting observation was noted and hence worth the archive for it.     Above is the chart of the Elliott Wave analysis of ThaiBev correction since the start in Aug 2016.  Applying the guideline that diagonal is allowed in the 5-wave for a corrective wave, it ended up the overall correction having a Double-three (flat - zigzag) pattern, a very common correction pattern nowadays.  The ((W)) wave itself is made out of a Flat (3-3-5) pattern, a 5-wave last leg ......
