Alot of people like round numbers.
Id say a far few added 10% to 27c & sold at 30c.
More bought at 30c added 10% and sold at 33c. Others that bought at 27-28c probably waited but were happy to sell at 33c as that gave them approx 20% profit.
Same scenario for 33 to 36c.
Not Elliot wave theory but Im sure theres some truth in the above and while I would loved 37.5c, there has to be some down days.
