Running Commentary on the SP Movements., page-4256

Hi all,
Firstly, thanks to everyone on this thread for all the useful information and commentary that is being shared. I have only recently started my journey in share trading and have already learnt a ton.

I am interested to hear anyone's thoughts on the recent fluctuations in the SP.
I have noticed since yesterday afternoon that the SP appears to swing by exactly .005 cents up and then down and then back again (at least that is how it is appearing in my CommSec account).
I get that there appears to be a strategy in place to cap the SP but what I am keen to understand is, how can it be controlled so precisely when there are a number of disparate groups buying and selling?

Thanks in advance
