What Is Sector Rotation in Crypto?

When BTC stabilizes, capital flows from BTC → majors → altcoins → narrative plays. Within altcoins, it flows from sector to sector based on which narrative the market is pricing in. Understanding which sectors are gaining (inflow) vs. losing (outflow) market cap tells you where smart money is positioning today.

This actor makes that signal visible in seconds.

Rotation Signals

Each sector gets a rotation signal:

Signal	Meaning
strong_inflow	+10% mcap change + high volume (breakout narrative)
inflow	+5% to +10% (gaining traction)
neutral	-5% to +5% (sideways)
outflow	-5% to -10% (capital leaving)
strong_outflow	-10%+ with volume (active sell pressure)
high_volume_flat	Flat price but 20%+ volume/mcap — accumulation or distribution
