I proposed to Coinbase that they show how many tokens

are ahead of your order in the queue when you hover over a price when you have an order placed at that price. I think it would give them more revenue. If you aren't close to being filled then you can cancel and enter order a tick better. If you are close to being filled, you can wait to get filled instead of canceling out of frustration since the order has sat so long. What do you think... helpful?

It depends how they assign the orders, who gets what and when. Imo, to do what you ask, you will have to update the entire queue each time a transaction is done which is very very cost ineficient. The thing is that there is more than just a queue. The matching is more complex than that, making the update process even more expensive.

It isn't more complex than that. It is a queue where orders are filled in the order they were entered. There isn't a matching system based on individual orders as you suggest. The formula is incredible simple to just keep removing fills from the number of tokens ahead of your order. Very basic and simple programming.

Are you sure? I always thought it was like that too, but I’ve definitely had experiences on CB Advanced where I place an order in at a price where there are no existing orders and then when it gets there I am not the first filled. Maybe it’s because a bot quickly jumped in front of me when I placed the order so was then considered “first in.” Either way, feels somewhat stacked against us. Fwiw, I like your idea and seems feasible if it actually is a simple queue and not a complex matching algorithm.

Once you place the order, you can see how many are available at that price. As you suggest, you will sometimes see a bot jump in front of you as you place your order so you aren't sure where you stand. Also, orders are entered and canceled all the time so you are never sure exactly where you are in the queue.

Yeah I realize there are always orders added and removed and I have always assumed it’s a basic queue so I generally expect 2 things: 1) if no other orders exist at a price and I place an order there, I should be first filled. 2) if my order at a price is partially filled and then price moves away, when it moves back to that price I’ll be first filled.

When do you see no orders at a price? I can't remember seeing that very often on Coinbase and not anywhere near best bid or ask. Unless you are talking about other than AMP trades.

Correct. Other than AMP.

Okay. If they are allowing others to jump the queue (especially if accepting payments to do so) then what I propose would catch it. They would be playing a dangerous game and the public relations nightmare over getting caught would be devastating.
