Previous highs and lows, such as yesterday's high, last week's low or the most recent swing high, are among the most watched levels on any chart. Price often moves towards them, reacts around them and sometimes briefly breaks them before reversing. Understanding why helps you set better targets, avoid poor entries and recognise traps.

Why price is drawn to them#

  1. Stop orders cluster there. Traders who are short often place stops just above recent highs; longs place stops below recent lows. That pool of resting orders is liquidity. See Liquidity in Smart Money Concepts.
  2. Breakout orders cluster there too. Traders wanting to buy a new high place buy stops just above it.
  3. Targets are set there. Many traders take profit at the previous high or low.
  4. Memory. Traders remember where price turned and react when it returns.

Three ways price behaves at a previous level#

The sweep is especially important: a brief break followed by a quick reversal often traps breakout traders. See Liquidity Sweeps and Stop Hunts and Failed Breakouts and False Breaks.

Using previous levels in trading#

As targets#

If you are long, the previous day or week high is a logical place to take some profit, because selling and stop orders sit there.

As entry filters#

Avoid buying just below a previous high where sellers may appear; either wait for a breakout and retest, or buy lower.

As stop placement guides#

Avoid placing stops exactly beyond an obvious previous high or low, where many others have theirs. A buffer beyond the level, or a position sized for a wider stop, reduces the chance of being swept out. See Stop Loss Strategies.

For bias#

Some day traders track whether price is trading above the previous day's high, below its low or inside its range, and adjust expectations: inside days often stay rangebound, breaks of both often mean trend days.

Combining with other tools#

  • Volume: a break of a previous high on strong volume is more convincing. See Volume Analysis Basics.
  • Higher timeframe structure: a previous daily high that is also a weekly resistance is a stronger level.
  • Candle confirmation: a close beyond the level matters more than a wick.

Common mistakes#

  • Buying every break of a previous high, including weak ones that reverse.
  • Shorting every touch, ignoring a strong trend that is likely to break through.
  • Putting stops exactly where everyone else does.

Frequently asked questions#

Why do traders watch the previous day's high and low?#

Because they are clear reference points where stops, breakout orders and profit targets cluster, so price often reacts there.

What does it mean when price breaks a previous high and reverses?#

It often signals a liquidity sweep: stops and breakout orders were triggered, but buyers could not sustain the move.

Are previous highs resistance?#

They often act as resistance, but in strong uptrends they are frequently broken and can turn into support afterwards.
