Support and Resistance Explained

The most useful concept in technical analysis: where price has turned before, and why it often reacts there again.

By Forex UK editorial teamUpdated 5 October 20267 min read

In short

  • Support — a zone where buying has stopped falls before.
  • Resistance — a zone where selling has stopped rises before.
  • Broken levels often flip roles.

How to find levels

  • Previous swing highs and lows — the clearest source of levels.
  • Round numbers — 1.2500, 1.3000 and other "big figures".
  • Previous day's and week's high and low — watched by many short-term traders.
  • Areas of congestion — where price spent a long time trading sideways.

Start on a higher timeframe (daily or 4-hour) and mark only the most obvious levels. Too many lines make a chart useless.

Role reversal

When resistance breaks, it often becomes support on a pullback — and vice versa. Many trend-following entries are built on this "break and retest" pattern.

Trading around levels

ApproachEntryStop-loss
BounceNear support in an uptrend or rangeJust below the support zone
BreakoutOn a close beyond the levelBack inside the previous range
RetestOn a pullback to the broken levelBeyond the retested level

Common mistakes

  • Placing stops exactly on a level, where they're easily hit
  • Treating every minor swing as a key level
  • Ignoring the bigger trend

Frequently asked questions

Are support and resistance exact prices?

Think of them as zones rather than single prices. Price often overshoots or falls short by a few pips.

Why do round numbers matter?

Levels like 1.2500 or 1.3000 attract orders and attention, so price often reacts near them.
