Quote from Candace:
Thanks for your reply. Sorry, I mistitled this thread. Because the broker id is listed on my t&s (on the TSX) it is clear who is buying and selling. On Friday, between 3pm and 4pm, one buyer bought 45,600 shares of POT for example (mostly in 100 share lots), but the chart gives you no clue that this is accumulation going on. There is so much back and forth buying/selling among the MM's that I just ignore their transactions, but I notice when someone else is in there repeatedly buying or selling. What I am asking is how to interpret it, or better yet, how to use it as a predictor.
My tinfoil hat theory was that on the big trend down day, either the sellers wanted to be seen or that the MM's wanted them to be seen. As it happened, this downtrending day was the beginning of many down days. But on Friday, it seemed as though the MMs allowed the buyer to accumulate without impacting the price. The only reason I could think of for a MM to do this would be if he believed price will gap up hugely soon. Why tip off all the parasitic traders like me?
But perhaps this theory requires more paranoia than I am capable of. A less paranoid explanation is that the buyer caught the MM at a time that he was flush with inventory.
Now if POT gaps up huge one day soon I may get the tinfoil out again.
