Why a zone and not a line
Drawing a line at one exact number assumes thousands of traders decided to buy at 2,380.00 rather than 2,379.50 or 2,381.20. That does not happen: interest spreads across a zone, which is why price overshoots a level slightly and then returns.
The practical consequence matters: a stop placed exactly beneath a round number is hit by noise alone. Leave room proportional to volatility — usually a multiple of ATR — rather than hugging the line. Applied to gold in gold support and resistance.
Three phases of one path
This family works from one chart: gold moves for several weeks between 2,380 and 2,420, then closes above 2,420 on rising volume, then makes a series of higher lows toward 2,500.
That single path passes through three phases — range, then breakout, then trend — bounded by support and resistance. What matters most is that a strategy correct in one phase is wrong in another: buying dips works in a range and is destroyed in a downtrend, while chasing breakouts works in a trend and bleeds in a range.
A worked example
On the reference chart, gold bounced from 2,380 three times and failed at 2,420 three times: the first is a support zone, the second a resistance zone.
When price closed above 2,420 and moved to 2,450, that level stopped being resistance and became potential support — the role swap. Those who sold there now buy there, because the level that repelled has become the level to defend. This is why the first pullback into a broken level is watched as a test of whether the breakout was genuine.
Common mistakes with this term
- Drawing the level as an exact line and hugging the stop to it, so noise takes you out before the idea is tested.
- Treating a level as valid forever; levels decay as time passes since their last test.
- Ignoring the role swap after a break and trading against the level as if nothing changed.
