I was just thinkingb about you. I place an order at a unique price and the bid becomes some multiple of my id. Say, I bid/offer 4 lots...immediately the total for bid/sale is 8,16, etc..

Am I first in line in the digital world or did they somehow read my order before it could be presented and get in line first?

And, don't get me started about entering an order at a price and instantly the price changes knocking me out of queue. that is, I enter to sell at 15.25 and the price becomes a tick or two away so my price never shows.

I remember our talks about algos years ago.

Hope you are well.
