Both crowds at once

Price reaches 2,431 and pushes a few dollars above it. Everything parked in that band fires at the same second.

One wave of buying

The buy stops fire and put one crowd into the market. The stop losses fire and take the other crowd out of it. Both of those are buy orders, so both add to the same wave.

For a moment there is far more buying at that price than the chart has seen for days.

When a high is taken, a burst of buying appears in one place.
