The mechanism, plainly
Take-profits cluster at the figure because someone thought I'll exit at 4400; entry limits cluster just around it; stops shelter just beyond it. The aggregation is genuine resting interest, which produces genuine reactions, no numerology required. The bigger the figure, century marks over half-century marks over tens, the wider its gravitational field, purely because more humans anchor to it.
The double edge
Obviousness giveth and taketh: the same clustering that makes figures react makes them premier raid targets, stops just beyond the 00 are the market's best-advertised pool, per the trap anatomy. Hence the characteristic round-number behaviours: the approach-stall, the sweep-through-and-reclaim, and the hard break that converts the figure into a durable reference for the other side.

Usage rules
Three honest applications: expect friction, targets just short of figures fill; entries at figures need the reaction confirmed, not assumed. Never park stops at the obvious shelf, beyond the figure by a hair, that is the harvest zone; structure-plus-buffer placement survives the sweeps. And rank figures as attention levels inside clusters: a century mark coinciding with real structure is a serious address; a bare figure mid-nowhere is a speed bump.
FAQ
Why does gold react at round numbers at all?
Order clustering: humans anchor exits, entries and stops at easy figures, and aggregated resting orders make any price real.
Should I place my stop just beyond a round number?
That shelf is the most-raided real estate on the chart. Use structural placement with a buffer past the figure's sweep zone.
Are round numbers as important as structural levels?
They are attention levels: meaningful mainly when they coincide with structure, where their crowd joins the level's real defence.
