What is a GLOB?

The main idea

Consider the time weighted average price order (TWAP), a common strategy for whales to lower price impact by splitting their trade into many smaller ones that are executed over time.

TWAP

Note how each individual trade is instant, but together they seem to approximate a continuous process of finite duration. Intuitively, the faster this duration is set, the higher the price impact will be.

Can we have markets that are so smooth that every trade must be a perfect, continuous stream, such that even the building blocks themselves are already streaming?

TWAP

The answer is yes. This idea, together with the one of limits recorded in a book, is the GLOB.

Context

We implemented the Gradual Limit Order Book (GLOB) as CosmWasm smart contracts. GLOBs enable a new way of trading without middlemen and were introduced and are studied further in
