BTC trends hard and then chops for weeks. Almost everything useful is either measuring that state change or giving you a level that the market has already proven it cares about.
ATR (14)
Volatility · every timeframe
Bitcoin's daily range can triple within a week. A fixed dollar stop that was sensible in a quiet range is inside the noise during expansion. ATR is what keeps stop distance and position size tied to current conditions instead of last month's.
50 and 200 EMA
Trend · 4h and daily
The 200-day in particular is watched by a very large share of the market, which makes it partly self-fulfilling. Price above a rising 50 EMA on the daily is the regime where long setups work; the two tangled together is the chop that drains accounts.
Prior range high and low
Structure · horizontal levels
BTC spends most of its life in ranges bounded by obvious highs and lows, and it repeatedly sweeps just beyond them before reversing. Marking those edges gives you both the entry level and the natural stop.
Volume profile / high-volume nodes
Participation · weekly or range-based
Shows the prices where the most contracts actually changed hands. Price moves quickly through thin areas and grinds inside thick ones, which explains a lot of otherwise baffling candle behaviour.
Funding rate and open interest
Positioning · perpetual futures
Not a chart indicator, but one of the highest-value inputs in crypto. Extremely positive funding with rising open interest means the market is crowded long — the setup for the long squeezes BTC is famous for.
RSI (14) divergence
Momentum · 4h and daily
Useful at range extremes and for divergence, not as an overbought reading. BTC routinely holds RSI above 70 for the entirety of a strong leg, and shorting that alone is a well-known way to lose money.
