# 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.

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?

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
