Volume zones and the point of control
The histogram down the side of the chart that shows where the market actually did its business — and the single busiest price inside it.
Where price stayed, not where it went
A price chart shows you where the market travelled. The volume profile shows you where it stayed. DarkWave splits each bar’s volume into buying and selling by where the bar closed relative to its open, spreads that volume across price bins over a long lookback, and lays the totals out as a horizontal histogram beside the chart. The longest bar is the point of control — the single price where the most business got done.
Neighbouring bins that lean the same way get merged into shaded zones. Where buyers dominated, the zone reads bullish; where sellers dominated, bearish; and where the two were close to even, the zone is marked contested — a stretch of price the market couldn’t agree on. Each zone carries the share of total volume it holds, so you can tell a heavy shelf from a thin one at a glance.
The point of control is the fairest price the market found. It’s the first magnet price tends to drift back to after it wanders off.
Read the profile as terrain. The point of control and the buyer and seller zones are the thick, well-supported ground; the thin bins at the edges are prices the market barely touched, which is exactly why they so often turn up as both targets and rejection points. Structure that lines up with a heavy zone is standing on something. Structure floating over a thin one usually isn’t.
