How Markets REALLY Work - Depth of Market (DOM)?

Markets are like a big playground where people trade toys, and Depth of Market (DOM) is like knowing how many kids want to buy or sell each toy right now.

Imagine you're at a swap meet, trading your favorite dinosaurs for shiny new cars. If lots of kids want the same car, it might get more expensive, just like when something is in demand. That’s where Depth of Market comes in: it shows how many people are ready to buy or sell at different prices.

How DOM Helps You Trade

Think of DOM as a scoreboard that tells you:

  • How many kids want to buy a car for $5, $6, or even $10
  • How many kids are trying to sell the same car for those prices too

If there are a lot of buyers at $6 and not many sellers, the price might go up, like when everyone wants the same toy and no one is willing to let it go cheap.

DOM helps you know if a toy (or stock) is popular or not. It’s like having a map that shows where all the kids are in the playground, so you can make smarter trades!
