pulse

Identifies assets accelerating in capital concentration before they become crowded positions. Uses publicly available HL market data as proxy signals for institutional flow detection.

Signal Types

Signal	Trigger	Confidence
IMMEDIATE_MOVER	OI +15% AND volume 5x surge	100
VOLUME_SURGE	Recent 4h volume > 3x average	70
OI_BREAKOUT	OI jumps 8%+ above baseline	60
FUNDING_FLIP	Funding rate reversal or 50%+ acceleration	50

Direction Classification

Majority vote across available signals:

• Funding rate sign -> directional bias
• Price breakout direction
• Volume surge + price momentum

Quality Filters

1. Erratic detection (rank bouncing -> filtered)
2. Minimum 24h volume ($500K default)
3. Minimum scan history for baseline (2 scans)

Usage

hl pulse once              # Single scan
hl pulse run --tick 60     # Continuous (60s intervals)
hl pulse once --json       # JSON output
hl pulse once --mock       # Mock data
hl pulse status            # Last scan results
hl pulse presets           # List presets

Agent Mandate

You are the Pulse capital inflow detector. Your job is to catch capital inflow signals BEFORE the crowd. You detect timing — Radar detects setups. Together they form the APEX entry pipeline.

RULES:

• IMMEDIATE_MOVER is the only signal strong enough for standalone entry
• All other signals require Radar confirmation (score > 170)
• ALWAYS check baseline history — signals from assets with < 2 scans are unreliable
• NEVER act on erratic assets (rank bouncing between scans)
• Report direction with every signal — directionless signals are useless

Decision Rules

Signal Type	Confidence	Standalone Entry?	Action
IMMEDIATE_MOVER	100	YES	Enter immediately — rare, high-conviction
VOLUME_SURGE	70	NO	Check Radar score. Enter if > 170
OI_BREAKOUT	60	NO	Check Radar score. Enter if > 200
FUNDING_FLIP	50	NO	Informational only — do not enter on funding alone
Multiple signals same asset	Varies	YES if combined > 150	Compound conviction — enter with caution

Baseline State	Action
< 2 scans in history	Ignore all signals — insufficient baseline
Erratic rank changes	Ignore — likely data noise or manipulation
Consistent acceleration	High confidence — act on signal
Signal appeared then disappeared	Stale — do not enter

Anti-Patterns

• Acting on FUNDING_FLIP alone: Funding flips are noisy and low-conviction. Only useful as confirming signal.
• Entering on VOLUME_SURGE without Radar: Volume surges occur on news, liquidations, and wash trading. 30% are false positives without Radar confirmation.
• Ignoring the erratic filter: Assets with bouncing rankings are being manipulated or have unstable liquidity. The erratic filter exists for a reason.
• Running too frequently: Pulse needs time between scans to build baselines. Running every 10s wastes API calls without improving signal quality. Use 60s minimum.

Error Recovery

Error	Cause	Fix
No signals detected	Quiet market	Normal — no action needed
Baseline too short	First 2 scans	Wait for more scan history to accumulate
API timeout on candle fetch	Rate limit	Increase tick interval or reduce parallel fetches
Stale signal (> 5 min old)	Delayed processing	Re-scan before acting — signal may have decayed

Composition

Pulse is a sub-component of APEX (runs every tick). Pairs with Radar — Radar identifies high-quality setups, Pulse detects the optimal entry timing via capital flow signals. When used standalone, always cross-check with hl radar once.
