Why would a person/entity keep a share price from exceeding a certain amount?

I've been watching $MYSZ for the last hour or so (3pm to 4pm) and whenever the price gets close to .77 a large ask size pops up for that amount. It eventually broke through but obviously there was an attempt to keep it down. Can anyone explain why that might happen?
