Gold's defining feature is the size and unevenness of its range. Almost every tool below is either measuring that range or giving you a level worth trading against.
ATR (14)
Volatility · the most important tool here
Gold's daily range can double around rate decisions. A fixed stop in pips that worked last week will be noise this week. ATR turns 'gold is volatile today' into an actual stop distance and lot size instead of a feeling.
21 and 50 EMA
Trend · 1h and 4h
Gold trends cleanly once it commits. Price holding above a rising 21 EMA on the 4h is a trend to trade with; the two EMAs tangled together is the range condition where most gold accounts get sliced up.
Session high and low
Levels · Asian, London, New York
The Asian session range is unusually reliable on gold: London frequently sweeps one side of it before the real move. Marking that range gives you both a level and a very common trap to avoid.
RSI (14) divergence
Momentum · 1h and 4h
Useful at levels, useless as an overbought reading. Gold can sit above RSI 70 for an entire trending week. Divergence into a prior high or a round number is the version that carries information.
Round numbers and prior day levels
Structure · psychological levels
Gold reacts hard at whole hundreds and fifties. Prior day high, low and close plus the nearest round number explain a surprising share of the intraday reversals people attribute to indicators.
Dollar index correlation
Context · DXY on a second chart
Gold is priced in dollars and usually moves inversely to DXY. A long gold setup while the dollar is breaking out is a trade fighting its main driver — worth checking before entry rather than after the stop.
