Sell-Side Liquidity

Resting sell limit orders above the current ask, waiting to absorb buy aggression.

Full Explanation

Sell-side liquidity is the collection of sell limit orders sitting at and above the current ask — participants who want to sell but are waiting for a higher price. When buy aggression arrives at these levels, sell-side liquidity absorbs it. The depth of sell-side liquidity at any price determines how much buy aggression is required before price relocates upward through it. Note: some trading communities use this term to mean clusters of stop orders below lows. In this framework, sell-side liquidity means resting sell limit orders.

Liquidity and Aggression

Every single trade has a buyer and a seller. That’s not an insight — it’s just math. For any transaction to happen, someone has to buy and someone has to sell. Which means that when you hear “buyers are in control right now” or “sellers are pushing price down,” you should pause for a second, because those phrases are telling you less than they sound like they are.

"Support and Resistance" — What You're Actually Saying

When you draw a line on a chart and call it support, you're making a specific mechanical claim. Most traders never examine what that claim actually says — or how much uncertainty it hides.
