How your order actually gets filled
Explain bid, ask, spread, depth and imbalance, and why a fill is never promised.
Module 3 of 26, Trends, order fills and a famous day-trading setup. Lesson 2 of 6, about 18 minutes.
The takeaway
The order book is a queue that keeps changing, not a promise that you will get filled.
This page is a public summary. The full lesson has the worked examples, an interactive exercise and a short quiz, and sits in the course. Lessons 1 and 2 of Module 1 are free and the rest need a pass.
