who is selling

I'm sorry fellas if my questions seem mundane but I am in a rapid learning curve and better ask than not.

Sharemarket is a massive congregation of peoples emotions. Everyone with there own agendas and reasons for why they invest/trade.

I at this point in time of SDL burgeoning career am struggling to find the reasons why people are selling shares now.

Any investor/fundamentalist with any idea is holding. Traders have had there fun with the pullback.Technicals are pointing up. If we are being manipulated they still need buyers for it to work.
Instituitions surely if investing are only buying, and a after numerous shakes of the tree are still getting many people in pain? I figure only people feeling financial pressure will sell now at such a pivotal point in SDL future

Why are sellers still in pain after a healthy correction and many chances for people to get out,yet the sellers still there in force.

All opinions will be greatly appreciated.
