since quite a while I am trying to figure out how blockvolume and orders in general are calculated and processed. You coded the platform so I think you can answer it best.
My question is basically in what cases does Blockvolume get recognized and how exactly are order processed.
For every buyer there is always a seller and vice versa. Will be both sides visible or just one? If just one, by which criteria does it select which side gets displayed, when several orders hit one bigger order like in the following exampel: Let's say there is a big 500 contract buy limit order that gets hit by 450 market sell orders. I guess in the tape this looks like 450 market sell orders, doesn't it? Since the blockvolume reads the 1 tick volume, I wonder if it gets the 500 buy limit at all? Are both, limit and market block orders, visible?
Cheers
