What are support and resistance?

Support and resistance are the price levels where a market has repeatedly struggled to fall below or rise above. Support is a floor where buyers keep stepping in; resistance is a ceiling where sellers keep taking over. They are the most basic idea in technical analysis, and almost every other tool — moving averages, Fibonacci, trendlines — is just a different way of finding them.

Why do these levels work?

Because markets have memory. A price where buyers once rushed in is a price where they may do so again — traders remember it, place orders around it, and the level becomes self-reinforcing. The more times price touches a level and turns, the more traders watch it, and the stronger it gets. When a level finally breaks, it often flips role: old resistance becomes new support, and vice versa.

How do moving averages fit in?

A moving average is a line that plots the average price over the last N periods — the 50-day and 200-day are the most watched. Traders use them as dynamic support and resistance: instead of a flat horizontal line, the level rises or falls with the trend. Price pulling back to a rising 200-day average and bouncing is the same idea as bouncing off a floor — just a moving one.

Where does Fibonacci come in?

After a strong move, markets rarely go straight — they retrace part of the way before continuing. Fibonacci retracement draws horizontal levels at set percentages of that move (38.2%, 50%, 61.8%) to guess where the pullback might find support or resistance. It is not magic math; it works partly because so many traders draw the same levels and act on them.

How do traders use them?

As a map, not a guarantee. Levels mark where risk changes: a trader might buy near support with a stop just below it, or watch for a break above resistance to signal momentum. Combine them with a read on volatility — the same level means something different in a calm market than in a violent one — and with broader currency strength to know which side of a pair has the wind behind it.

The takeaway

Support and resistance are simply the prices where a market has paused before. Horizontal levels, moving averages, and Fibonacci are three ways of finding them. None is a crystal ball — they are zones where the odds shift, and where the market tells you quickly whether you were right.
