Introduction

The cross exchange market making / Hedged Market Making strategy performs market making trades between two markets:

• It emits limit orders to a less liquid, larger spread market.
• It emits market orders on a more liquid, smaller spread market whenever the limit orders were hit.

Market making isn't about placing bunch of bids and asks orders, you will soon realize orderflow isn't random at all and you get filled irregularly and accumulate inventory(which is a serious risk). Hedged Market making can help you with the inventory risk, unless you are slow somewhere. Basics remains the same, MM is all about capturing the spread and managing your inventory. You need to price in information as much as possible in a very low latency manner.

Architectural Design

Components are scheduled to execute on distinct CPU cores using thread affinity and CPU isolation, which helps in preventing a thread from wandering between CPUs and reducing context switching overheads. Component Threads are expected to busy poll and never be interrupted, as it reduces the number of context switches because context switches only happens at each time slice.

Risk Management Tools

• If speed of arrival market orders picks up across exchanges, stop quoting.
• BART move detections helps in determining taker exchange overloads.
