This jumped out at me when viewing the weekly chart : The formation is similar to some variant of a complex IH&S. The head would be the floor at $13.73 and the neckline is the top blue line, downward sloping from $54 to its current price at about $45. If the pattern is legitimate and Twitter broke above it, the measured move would be toward the $80 region. Aggressive traders may be able to find a long entry on a shorter timescale, but there is resistance from the downsloping black and blue lines.
