Levels are the backbone of almost every trading system. Here is where they come from and how to tell a real level from a line drawn by eye.

Why levels work

A level is a price where a lot of trading happened before: orders, stops and liquidations of those who entered nearby sit there. Traders remember these prices and place orders there again. Support is a zone where buyers have defended the price before; resistance is where sellers have stopped a rally.

How to find them

Start with a higher time frame: several touches with a bounce, round numbers, previous all-time highs and lows, zones of heavy volume. A level is a zone, not a one-pixel line.

How to confirm them

On a chart a level is visible only in hindsight. The live confirmation is the order book. If a large limit wall has been sitting at the level for hours, real money is defending it. You can see it on the order book heatmap. If the wall vanishes as price approaches, it is probably spoofing.

The second source is the liquidation heatmap. A liquidation cluster beyond a level is fuel: if price breaks it, forced trades will speed up the move.

Breakout or fakeout

A real breakout usually comes on volume and holds: price closes beyond the level and then retests it from the other side. A fakeout is a quick poke that collects stops and sends price back. These pokes often line up with liquidation clusters.
