Execution Latency in My Polymarket Trading Bot - Sub-Second Trade Execution System Design

Speed on Polymarket is not what I thought it was when I started building this.

I assumed faster was always better. Get the signal, fire the order, win. Turns out the execution problem on Polymarket is more interesting than that - and the bottlenecks are not where most people expect them to be.

This is the execution layer behind a bot that's placed 11,717 trades. Here's what I learned building it.
