Hi Richard,
I just edited the attachment as you'd left the ticker symbol in the eSignal box.
I haven't cheated, but I'm going to look at the chart when I've posted & see how wrong I am ... I cannot understand L2.
My instinct is to say, well, 32.75 will become a support level as the size bidder soaks up any weak hands' selling, probably selling from those who do not have a L2 view. Once he has finished soaking it up, accumulating it, then the price can be allowed to rise significantly.
But if you wanted to buy that much stock, genuinely, why would you advertise this intention so obviously? Anyone with L2 will see the bid and think, "Oh good a huge support level provided by a big player who is wanting to buy size because he thinks it is going up." So nobody sensible would sell any of their stock to him, well assuming they had L2 and they thought he was genuine, no in fact they'll probably all start buying, following the smart bidder, thus denying our big player a lot of the stock he wanted at 32.75.
So he should pull his bid for a minute or two and watch what happens. Does the stock drop just a level or two or does it cause a rush of selling? He pulls his bid to test supply below the support level he's just created. If there isn't much supply then he can start buying in earnest, as all the weak hands have been washed out and the price must now go up. If there is, and the stock drops several levels then he may rethink his strategy and try and buy lower than the 32.75 that originally looked attractive.
Level 2 confuses me because there seem to be so many interpretations of a given snapshot. Maybe that big bidder is actually a seller pretending to be a buyer. While he sits there 348 bid he's offering out lots of 10, 50 and 75 simultaneously through ISLD, his big bid stopping the price from falling while he distributes. Maybe he's a genuine buyer, maybe he's just faking a bid to test the water, to see what happens ... it's too much for my small brain anyway.
