Reversal Zone
One twenty-point band. Five ratios inside it: absorption, hidden size, large prints, book wall, rejection. Never raw volume as a score, because that just crowns wherever price already is. Direction comes from the absorbed side. Untouched bands fade, then drop.
Liquidity Vacuum
A vacuum only when volume, time spent, and resting size are all thin. Sparse stripes, not a block. A target belongs past the emptiness, not inside the next zone. Absence has to look like absence.
MM Radius, same chart
The MotiveWave port keeps the Pine arithmetic: Yang-Zhang, the snap to prior high or low when the two land a handful of ticks apart, the day boundary made explicit. Trade the same levels on either platform.
The licence
A key in ~/.daelta/license.key. It binds to one machine. Fourteen days offline. A dead server is not a refusal. Only an explicit no turns the studies off. Revoke, and every copy that asks about that key goes dark.
