Comment:

*TBTL -- Ten bars and two legs - thats the MINIMUM move that can be expected from a successful MTR

Comment:

Also Major does not imply a market crash or a very huge move, It just implies according to the source a significant change in market cycle from a trend to sideways to down price action that creates a bigger trading range which includes the previous up move / trend .

Thus changing the market cycle from Trending to Two way (Ranges) post which market makes new decisions and market cycle resumes to a new phase after price discovery.
