No-one has such a view. Technically, no orders exist until the order book opens for entry at 0750. At that point, any DMA orders will be visible to those with L2 access. Orders that aren’t being executed via DMA (the overwhelming majority for PI’s, specifically those trying to get “at market” orders quoted) won’t be visible other than to individual RSP’s polled after the open at 0800. There is no aggregating mechanism for these, no-one sees the whole market in the way you suggest.
For those expecting/creating a panic on Monday morning, I hope no-one is foolish enough to enter an “at market” trade on open. MM’s will likely be waiting - you have been warned - and you may get filled at a price you don’t like. If you feel like placing yourself alongside the MM’s rather than in opposition to them, a speculative limit buy order at a low price might get filled early in the session...
Posters here saying that they’ve already input their sell orders will mainly be fantasists looking for peer approval on this board. You’ll see this on Monday morning when the whole idiots parade of dummy trades and “NT to buy/sell” kicks off.
