You're probably thinking of my post from a few weeks ago in this thread https://news.ycombinator.com/item?id=16922538

I'm tracking order positions with an in memory orderbook. When gdax accepts my order I know where I end up. I average spot 1.45 when the spread changes. It's hard to get closer to perfect 1.00 because of limit taker orders which, if placed right, always get 1.00 after the taker portion is calculated and the maker is placed 1 cent from other other side.

Yes, but you still didn't address the question of what are you basing your claim of being the fastest off of.

What?

He asked you how you know your bot is the fastest, and if you can prove it.

I answered it already. When the spread changes my bot is the first one to the new best bid / ask.
