Agent 03 · Signal

Score the edge.
Rank the conviction.

The Signal agent is Harbor’s live admission engine. It turns technical structure, confirmation, and relative strength into governed candidates the rest of the chain can challenge. Its importance to the universe is simple: if Signal admits the wrong names, everything downstream starts from bad evidence.

Four verdicts. One frontier.

Signal scans the full universe, resolves every name into a verdict, then only lets the strongest setups advance. This is the live frontier where technical opportunity becomes governed candidate flow.

Strong Buy
Score ≥ 0.80

High confluence. Harbor can move it into downstream challenge and governance with full conviction weight.

Buy
Score 0.60 – 0.79
0

Qualified long idea. Strong enough to advance, but not a top-tier leader yet.

Watchlist
Score 0.40 – 0.59
0

Interesting but incomplete. Logged for monitoring, not admitted into the governed chain yet.

Blocked
Below threshold or constrained
4

Signal sees structure, but admission logic or constraints prevent promotion into the chain.

Valuation

Signal sits between context and challenge. Macro and Sentiment shape the field; Signal decides which setups are worthy of deeper valuation, risk, and routing.

Signal Composition

What builds the score.

Signal blends four families into one composite read, then checks how cleanly the evidence aligns before publishing a candidate.

TS
Technical scoring

Evaluates structure, support, resistance, and multi-timeframe alignment so price action has to earn trust before Harbor promotes it.

technical
MS
Momentum models

Tracks acceleration, relative strength, and trend persistence to separate durable pressure from short-lived bursts.

momentum
VA
Volatility adjustment

Adjusts raw signal quality by volatility posture so the same setup is interpreted differently under cheap and expensive risk.

vol
FA
Fundamental overlay

Adds a light sanity check so obviously deteriorating names do not look clean simply because the chart is temporarily cooperative.

fundamental
MT
Multi-timeframe alignment

Rewards agreement across daily, weekly, and broader structure because full alignment is one of Harbor’s strongest confluence signals.

confluence
SL
Sleeve rotation

Ranks sleeves by aggregate signal quality so Harbor can see where technical opportunity is broad versus isolated.

allocation
Lane 01
Trend structure

Signal first checks whether the move has durable structure instead of one-day noise. Clean posture is the base layer of conviction.

Lane 02
Momentum quality

Momentum matters, but Harbor cares how it is built: accelerating cleanly, degrading, or already overextended.

Lane 03
Confirmation stack

Relative strength, weekly confirmation, and local feature quality must agree before Signal publishes a serious candidate.

Lane 04
Admission pressure

Signal is not just scoring. It is deciding what earns a place in the governed chain and what gets left outside.

Universe importance

Signal is the layer that converts a broad universe into an actionable frontier. If this gate is weak, Harbor wastes downstream attention on noise. If it is strong, every later agent starts from cleaner evidence.
