A price level where buyers have historically stepped in to stop the decline and turn price back up.
Support is a price level where demand has historically been strong enough to absorb selling pressure. On a chart, you can see it as a horizontal line where price has bounced multiple times before. Each bounce creates a memory — more traders expect it to hold next time, which makes it self-fulfilling to a degree.
Support isn't a precise price, it's a zone. The more times price tests and holds a level, the stronger it becomes. The more times it's tested, the more likely it is to EVENTUALLY break — because stops build up under it.
When support breaks decisively, it often becomes new resistance (a concept called "role reversal"). Everyone who bought at support is now losing money — when price comes back to that level, they sell to get out at break-even, creating new resistance.
Real trade example
GBP/USD 1.2500 was a major support all through 2023 — tested 5 times before finally breaking in Jan 2024, which triggered a 400-pip drop.
Frequently asked about support
What is a support in trading?+
A price level where buyers have historically stepped in to stop the decline and turn price back up.
When will I see support used in real trading?+
On every chart. Support is one of the first things pros mark when they open a chart — usually daily/weekly horizontal levels.
What is the most common mistake traders make with support?+
Drawing support at the exact low of a single candle. Support is a zone — draw it across MULTIPLE candles that reacted to the same area.
What do experienced traders know about support that beginners don't?+
Mark only the support that shows up on daily and weekly timeframes. Intraday support on the 5-minute chart is noise — the big money only cares about big-timeframe levels.
