What support and resistance are

Support is a price area where falling prices have repeatedly found enough buying to stop or reverse. Resistance is the opposite — an area where rising prices have repeatedly met enough selling to stall. Think of them less as exact lines and more as zones where the balance of supply and demand shifts.

Why these levels form

Levels form because markets have memory. Traders remember where they bought or sold and react around those prices again. Three forces reinforce a level:

  • Memory: people who missed a move want a second chance at the same price.
  • Liquidity: resting orders cluster at obvious prices, creating walls that absorb pressure.
  • Self-fulfilment: the more traders watch a level, the more their orders make it real.

Horizontal vs dynamic levels

Horizontal levels are fixed prices — prior swing highs and lows, range edges, or psychological round numbers. Dynamic levels move with price, such as moving averages or trendlines. Both work; the strongest setups appear where several types overlap, a condition traders call confluence.

Role reversal

Once broken, support often becomes resistance and vice versa. A ceiling that finally gives way frequently becomes a floor on the pullback, because traders who were trapped above now treat that price as a chance to exit at breakeven.

Breakouts versus fakeouts

Not every touch of a level breaks it, and not every break holds. A genuine breakout usually shows expanding volume and a decisive close beyond the level. A fakeout pierces the level briefly and snaps back, trapping breakout traders. Waiting for a candle to close beyond a level — rather than reacting to the first touch — filters out many fakeouts.

Combining levels with RSI

Support and resistance tell you where a reaction is likely; RSI tells you whether momentum agrees. Price reaching support while RSI is oversold on RSI Monitor is a higher-quality bounce setup than support alone. A resistance test that coincides with bearish RSI divergence is a classic rejection signal.
