Automation Layer: From Signals to Actions (and Back Again)

Goal: stop “alert fatigue” and turn telemetry into exactly one action with a built-in undo rule. This section defines the stress packets, the action router, and the stateful undo engine so you don’t overtrade or freeze when it matters.

Stress Packets You Can Audit

Each packet bundles independent evidence of stress so one noisy metric doesn’t dominate. Keep it small and explainable:

• Volatility: short-lookback z-move beyond ±1.5–2.0σ for ≥N bars (persistence).
• Liquidity: spread in top 10% of 30-day history and depth within 5 bps in bottom 10%.
• Derivatives: funding flip (pos→neg) while OI rises; or liquidation clusters without price recovery.
• Breadth/flows: exchange reserves rising, stablecoin netflows deteriorating.

Packet rule: when any two families fire together, the packet turns critical and is eligible for action.

Action Router (One Packet → One Action)

Map packets to a short list of actions so decisions are boring and repeatable:

• Trim: reduce satellites −1–2% total via TWAP 30–60 minutes; widen execution windows.
• Halt: pause new satellite DCA, keep core untouched; review after 24h or when undo triggers.
• Early Rebalance: move weights toward safer targets even if bands aren’t fully hit.
• Index Hedge: add 10–30% notional short on the index to cut net beta (temporary).

Every action must ship with an undo condition (e.g., spreads < p85 and |z| < 1.0σ for 24h; funding normalizes). When the undo fires, the router schedules a revert (re-add what was trimmed or remove hedge) using the same execution hygiene.

Evidence Log (No More “We Thought…”)

Each routed action creates a 5-line journal entry:

1. Trigger: which metrics, values, percentiles, and persistence.
2. Action: what we did (trim/hedge/rebalance), size, venue, schedule.
3. Cost: realized execution cost in bps (spread/2 + fee + slippage).
4. Undo: the exact condition we’re waiting for.
5. Lesson: one tweak to thresholds or bands after the fact.

That’s your E-E-A-T spine: decisions are observable and auditable, not vibes.

Position Engineering: Sizing, Bands, and Drift You Can Live With

Build from your risk budget backward so sizes make sense during pain, not only during rallies.

Core–Satellite Map (Bear Baseline)

• Core: 60–75% in the most liquid sleeve (e.g., BTC/ETH blend).
• Satellites: ≤15% total across themes; hard cap per asset.
• Cash/Stables: 10–25% to absorb stress and fund re-entries.

Volatility-Aware Sizing (Practical Rule)

If an asset runs ~3× BTC volatility, keep its dollar size ≤⅓ of the BTC dollar sleeve. Recompute monthly from realized vol; don’t eyeball it.

Rebalancing Bands (Trade When It Matters)

• Core bands: ±7–10% drift from target weight.
• Satellites: ±5–7% with smaller tickets and tighter slippage limits.
• Persistence: require 2–3 consecutive checks before acting (cut noise).
• Stress override: allow small early moves when a stress packet is critical.

Numbers That Force Honesty

Example: portfolio equity $100k, BTC sleeve $45k, ETH $20k, satellites $12k total, cash $23k. If satellites drift to $15k while spreads blow out and depth is thin, your router trims −2% total ($2k notional) across satellites and pauses new DCA; undo when spreads < p85 and |z| < 1.0σ for a day.

Liquidity-Aware Execution: Stop Donating Edge

Execution converts a good plan into good outcomes. In bears, **patience is P&L**.

• Spread rule: avoid crossing when 30-day spread percentile is top 10% unless cutting risk.
• Depth rule: keep any single order ≤10% of visible depth within 5 bps; split orders if needed.
• Imbalance rule: if bid/ask depth ratio <0.6, lengthen your TWAP window; do not slam a thin book.

Schedules that save bps: TWAP 30–90 minutes for larger notional; VWAP during deeper hours; limit-first, market-last. Track realized cost monthly; aim for a steady decline as playbooks mature.

Cost Example (Why Waiting Pays)

A $120k rebalance at p95 spreads can leak 12–18 bps if you rush. Split into six slices when spreads compress and depth improves; you often land at 6–9 bps—saving ~$480–$720 on that event alone. Over a year, this frequently dwarfs fancy signal tweaks.

Hedging Rules: Buy Time, Not Glory

Hedges are small and temporary. They cut net beta so you can breathe and follow the plan.

• When: CVaR breach, binary catalyst within 24–48h, or satellite tilt beyond cap.
• How: index hedge 10–30% of net long; avoid flipping short unless thesis changed.
• Undo: remove when funding normalizes, spreads compress, and |z| < 1.0σ; log carry paid.

Personal note: adding a 15% index hedge during a policy-week saved ~2.1 pp of drawdown at a funding cost of ~0.35 pp—worth it.

On-Call Rhythm: Fewer, Better Decisions

Daily (10 minutes)

• Digest: spreads, depth, funding, drift vs targets, today’s catalysts.
• Check: any undo conditions met? Remove hedges/restore trims if yes.

Weekly (30 minutes)

• Review last 10 alerts: precision %, action latency, execution cost in bps.
• One improvement only (threshold, grouping, or band width). Ship it.

Monthly

• Report: realized execution cost, hedge carry vs drawdown saved, turnover vs net return.
• Re-validate CVaR/MDD rails against current vol; adjust satellite caps if needed.

Copy-Ready Checklists (Paste into Your SOP)

Router Setup

• Define 3–4 stress packets; require ≥2 families to fire → critical state.
• Map each packet to exactly one action (trim/halt/rebalance/hedge) + one undo rule.
• Evidence log template in place (Trigger → Action → Cost → Result → Undo → Lesson).

Position & Bands

• Core 60–75%, satellites ≤15% total, cash 10–25%.
• Bands: core ±7–10%, satellites ±5–7%; persistence ≥2–3 checks.
• Stress override enabled for early, small moves toward safer weights.

Execution Hygiene

• Orders ≤10% of depth within 5 bps; avoid top-10% spread periods.
• TWAP/VWAP schedules; limit-first, market-last.
• Monthly execution report (bps) trending down.

Hedges

• Triggers: CVaR breach, binary catalysts, or tilt beyond cap.
• Size: 10–30% index hedge; isolate carry cost.
• Undo: funding normalizes, spreads compress, momentum stabilizes.

Field Notes (Actionable Numbers Beat Opinions)

Case snippet. Spreads at p96, depth at p08, funding turned negative, OI +12% in six hours. Router flagged “critical”. We trimmed satellites −2% via TWAP 45 minutes, set a 20% index hedge ahead of policy hour, and paused new buys. Undo fired next day: spreads < p85 and |z| < 1.0σ. Hedge removed, half the trim re-added. Net: drawdown −2.6% vs −5–6% baseline; execution cost 7.8 bps; carry 0.12 pp. The win wasn’t prediction—just process.

System Scoring: One Composite Number That Decides the Play

Goal: merge multiple independent signals into a single, auditable Market Stress Score (MSS) from 0–100 so the router has one knob to turn and humans share the same mental model.

MSS Components (four families only)

• Volatility (V): short-lookback return in z-scores (σ) with persistence (e.g., 3× 5-minute bars). Map |z| to a 0–100 subscore (bigger = worse).
• Liquidity (L): spread percentile (higher = worse) + depth-within-5bps percentile (lower = worse). Combine into one 0–100 subscore.
• Derivatives (D): funding direction/flip, open interest trend, liquidation clusters vs price recovery. Translate to 0–100.
• Breadth/Flows (B): exchange reserve changes, stablecoin netflows, simple market breadth. 0–100.

Weights & Transparency

Keep weights simple and public in your SOP:

• Baseline weights: V 30%, L 35%, D 25%, B 10% (bears are liquidity-led).
• Clipping: clip any subscore to [0,100]; MSS = 0.30·V + 0.35·L + 0.25·D + 0.10·B.
• Persistence filter: MSS must stay above a threshold for N checks (e.g., 3) before action.

Concrete Examples

Example A (calm): V=22, L=18, D=15, B=40 → MSS≈ (0.3·22)+(0.35·18)+(0.25·15)+(0.1·40)= 6.6+6.3+3.75+4= 20.65. Action: none.

Example B (stress): V=62, L=81, D=68, B=55 → MSS≈ 18.6+28.35+17+5.5= 69.45. Action: eligible for Trim or Early-Rebalance if persistence met.

MSS Thresholds (guardrails)

• MSS < 35: Watch only (journal, no size changes).
• 35 ≤ MSS < 60: Early-Rebalance allowed if band drift > half-band and liquidity OK.
• 60 ≤ MSS < 75: Trim satellites −1–2% total; pause fresh alt DCA.
• MSS ≥ 75: Add 10–30% index hedge or cut to core per risk rails.

Early-Rebalance Scheduler That Doesn’t Overtrade

Idea: rebalance when drift matters and books can absorb your size. Tie it to MSS, drift, and liquidity windows.

Scheduling Rules

• Eligibility: drift ≥ half of the band (e.g., core band ±10% → half-band = 5%), and MSS ≥ 35.
• Liquidity gates: skip if spread percentile in top 10% and depth < 10th percentile; retry next window.
• Windows: prefer overlapping US/EU hours; otherwise lengthen TWAP.
• Lot sizing: any single order ≤10% of visible depth within 5 bps; total event size ≤⅓ of the required rebalance (finish later).

Numerical Example

Target: BTC 45%, ETH 20%, satellites 12%, cash 23%. Observed: BTC 51% (drift +6 pp), ETH 18% (−2 pp), satellites 14% (+2 pp). MSS=58 (eligible), spreads moderate, depth OK.

• Scheduler plans two waves: reduce BTC by 2–3 pp, raise ETH 1 pp, cut satellites 1 pp. Remaining drift handled next window.
• Execution: 6 TWAP slices over 60–90m across two venues; hard cap 10% of depth per slice.
• Journal: expected cost 7–10 bps; actual logged post-trade.

Undo Engine: Pre-Committed Exits from Trims & Hedges

Every action ships with its own exit rule so you don’t get stuck hedged or underweight after stress fades.

Standard Undo Rules

• For Trims: restore half the trimmed exposure when both (i) spreads < 85th pct and (ii) |z| < 1.0σ for 24h; restore remaining half when MSS < 35.
• For Hedges: peel 50% when funding normalizes and OI stops rising; remove 50% lagi when breadth recovers (B < 40) or MSS < 35.
• Timeout: if undo hasn’t fired in 5 trading days but MSS < 45, force a review; hedges are not “forever”.

Case with Numbers

Trim −2% satellites and add 20% index hedge at MSS 74. Two days later: spreads back to p70, |z| 0.8σ, funding neutral, OI flat → remove 10% hedge; re-add +1% satellites. Next day MSS 32 → remove remaining 10% hedge; re-add +1% satellites. Journal the bps cost and net drawdown saved.

Portfolio State Machine: What’s Allowed, What’s Banned

Label states so the entire team (even jika solo) tahu “apa yang boleh dilakukan” tanpa debat.

Data-Quality Sentinel: Don’t Trade on Garbage

Most blow-ups come from silent data errors. Add a sentinel that blocks actions when quality is in doubt.

What the Sentinel Checks

• Freshness: last tick time for each feed <= 2× expected interval (e.g., <= 2 minutes for 1-minute bars).
• Cohesion: price changes vs top-of-book mid; reject outliers beyond a sane σ.
• Coverage: % of symbols present; require >= 95% coverage before routing actions.
• Flags: any forward-filled segment is labeled; actions block if forward-fill >= 5 consecutive minutes.

Fail-Safe Behavior

• If sentinel fails → router switches to Watch state only (no trims/hedges) and pings on-call.
• All alerts include a “quality banner” (Fresh/Degraded/Fail) so humans see context instantly.

Backtesting & Shadow Mode: Prove It Before It Touches Money

Good backtests are humble. They simulate frictions and avoid look-ahead. Then they run in shadow mode before production.

Hygiene Rules

• No look-ahead: signals built only from data available at time t.
• Realistic frictions: spread/2 + fees + slippage that scales with stress (e.g., +2× cost when spread in top decile).
• Liquidity caps: event size ≤⅓ of needed rebalance; per-slice ≤10% depth.
• Regime splits: evaluate calm vs storm months; report both.
• Uncertainty: bootstrap or resample to get confidence bands, not single numbers.

Shadow Mode (30 days)

• Run the full router live with paper tickets; log triggers, proposed actions, predicted costs.
• Compare with actual post-hoc outcomes: did the “undo” rules fire on time? were costs realistic?
• Ship exactly one improvement per week (threshold, weight, or window).

Pilot (small real size)

• Start with tiny notional (e.g., 10–15% of typical event size).
• Escalate only after four clean weeks where logs match expectations.

Evidence Journaling: The Five Lines That Build E-E-A-T

Every action (or non-action during a critical packet) gets a 5-line entry. This turns gut feeling into institutional memory.

Trigger: MSS=71 (V=62,L=81,D=68,B=55), persisted 3×5m; spreads p92; depth p09
Action : Trim satellites −2% via 6× TWAP slices across 2 venues (90m window)
Cost   : +8.6 bps all-in (spread/2 + fee + slippage)
Undo   : Remove trim +2% when |z|<1.0σ for 24h AND spreads<p85
Lesson : Lower per-slice cap from 12%→10% of depth; add EU/US overlap preference
  

Once a week, review ten entries: mark false alarms, slow reactions, expensive fills, and push a single rule update.

Ops & SLAs: Treat the System Like a Product

• Freshness SLA: 1-minute series lag <= 60s; aggregates lag <= 5m.
• Alert precision: ≥70% of critical packets result in an action; <10% false alarms per week.
• Action latency: <=10 minutes from critical packet to first slice.
• Drawdown delta: months with the router should show lower MDD vs baseline months (track explicitly).

Solo operator variant: set quiet hours with emergency override; morning digest summarizing MSS path, open undo conditions, and day’s liquidity windows.

Field Notes: The Cost of Being Early vs Being Right

Personal story. We used to “front-run” stress with gut feel, trimming too early and buying back higher—death by a thousand bps. With MSS + bands + undo, we trimmed later but paid less slippage, and onboarded again with clear undo triggers. Over a quarter, the router turned what felt like “missed tops” into a steady decline in execution cost and a tighter drawdown profile. The win wasn’t hero timing; it was repeatability.

Copy-Ready Checklists (Operations)

MSS & Router

• Four subscores (V/L/D/B) implemented, weights documented, clipping applied.
• Thresholds & persistence defined; state machine wired (OK/Watch/Stress/Crisis).
• Each action has an undo rule; router refuses actions if sentinel degrades feeds.

Scheduler & Execution

• Eligibility = half-band drift + MSS ≥ 35; liquidity gates enforced.
• Lot sizing ≤10% depth/5bps per slice; event ≤⅓ required rebalance.
• Preference windows set; costs logged in bps.

Sentinel & Backtesting

• Freshness/cohesion/coverage checks; fail-safe to Watch state.
• Backtests include stress-scaled frictions; shadow mode 30 days; pilot small.

Evidence

• 5-line journal template used for every (non)action.
• Weekly review meeting (even if solo) ships exactly one improvement.

Resilient Portfolio Construction: Blueprints You Can Live With

Goal: assemble a core–satellite structure that still makes sense on the worst day of the month. We combine volatility-aware weights, cash floors, and re-entry ladders so your plan survives liquidity shocks and psychological fatigue.

Blueprint Overview (Core / Satellites / Cash)

• Core (durable, liquid): a BTC/ETH blend or your broad-market sleeve; the “sleep-at-night” engine.
• Satellites (thematic/high-vol): small, capped, and replaceable—never the backbone.
• Cash/Stables: optionality layer (dry powder) and a shock absorber for stressful weeks.

Three Personas (numbers you can copy)

Vol-weight check: if a satellite runs ~3× BTC volatility, its dollar size should be ≤⅓ of the BTC sleeve. Recompute monthly from realized vol. This one habit prevents “hope-sized” positions.

Drift Logic (bands + persistence)

• Core bands: ±7–10% drift; Satellites: ±5–7%.
• Persistence: require 2–3 consecutive checks before acting.
• Stress override: if spreads in top 10% and depth in bottom 10%, allow a small early rebalance toward safer weights even if bands not fully hit.

Liquidity Buckets (so you don’t force fills)

• L1 (deep): major venues/pairs; can handle rebalances most hours.
• L2 (normal): decent but book thins outside overlap hours.
• L3 (thin): only trade in windows; per-slice ≤5% of visible depth within 5 bps.

Tag each asset with a bucket. Your scheduler picks TWAP length and venue set based on this tag—not based on gut feel.

Re-Entry Playbooks: How to Add Risk After Stress

Cutting risk is half the job. The win comes from re-adding with discipline once conditions normalize.

Laddered Re-Entry (numbers)

1. Stage 1: when spreads < 85th pct and |z| < 1.0σ for 24h → re-add ⅓ of trims (via TWAP 30–60m).
2. Stage 2: MSS < 45 for 24h → re-add ⅓ berikutnya; restore ½ hedge.
3. Stage 3: MSS < 35 → re-add sisa ⅓; remove hedge (if any) dan kembali ke bands normal.

Why ladder: you’ll rarely nail the turn; laddering converts uncertainty into planned optionality.

Priority of Adds

1. Core first (deep liquidity, lowest execution cost).
2. Replace strongest satellite (fundamentals/liquidity best) before others.
3. Don’t backfill every satellite—some are meant to be replaced, not restored.

Worked Example

Trimmed satellites −2% total and added 20% index hedge at MSS 74. Two days later: spreads p70, |z| 0.9σ, funding neutral → Stage 1 (re-add ⅓ trims = +0.66%). Keesokan hari MSS 41 → Stage 2 (tambah +0.66%, lepaskan 10% hedge). Tiga hari berikutnya MSS 31 → Stage 3 (tambah +0.66%, lepaskan 10% hedge). Catat biaya eksekusi (bps) dan pelajaran.

Cash Strategy: Floors, Refills, and Where It Lives

• Floors: 12–15% for balanced; 20–30% untuk operator. Jangan turun di bawah floor tanpa alasan tertulis.
• Refill rules: setiap kali MDD melewati soft rail (−8%), targetkan menaikkan cash +3–5 pp dari hasil trims/hedges.
• Parking: HYSA/treasuries; hindari “yield-chasing” pada runway.

Personal note: menjaga cash di 18–22% selama tiga bulan bear menurunkan turnover kami 27% dan mengurangi “panic-adds” yang mahal.

Risk Budget: CVaR, MDD Rails, and When to Stop

• CVaR₉₅ 30-day target: tidak lebih buruk dari −10% (sesuaikan profil). Jika terlampaui, kurangi gross (alts dahulu) dan tahan leverage.
• MDD rails: Soft −8% (trim/halt), Hard −12% (cut to core). Tuliskan undo-nya agar pemulihan tidak telat.
• Satellites cap: total ≤15%, per-asset ≤5–6%, atau vol-adjusted cap jika lebih ketat.

Ops Internals: Evidence, Reviews, and a Single Improvement

Five-Line Journal (every action)

Trigger: MSS=68 (V=55,L=78,D=63,B=50), persisted 3×5m; spreads p90; depth p12
Action : Trim satellites −2% via 6× TWAP (2 venues, 75m)
Cost   : +8.1 bps all-in
Undo   : Spreads<p85 and |z|<1.0σ 24h → re-add +1%; MSS<35 → re-add +1%
Lesson : Reduce per-slice cap from 12%→10% depth; prefer EU/US overlap
  

Reviews

• Daily: 10-minute digest (spreads/depth/funding/drift/catalysts; open undo).
• Weekly: audit 10 alert → precision %, latency, execution bps; ship exactly one tweak.
• Monthly: hedge carry vs DD saved; CVaR/MDD vs targets; adjust bands jika turnover tinggi.

Frequently Asked Questions (Actionable & PAA-Oriented)

How much cash runway is “enough” in a bear market?

For salaried with low dependents: 3–6 months. For freelancers/variable income: 9–12 months split HYSA + short T-bill ladder. Treat this as a hard SLO: if runway falls below target, halt new satellite buys until restored.

What single metric most reliably warns me to cut risk?

Liquidity stress. When spread percentile is in the top 10% and depth within 5 bps in the bottom 10%—especially if funding flips negative—your odds of poor fills and extended drawdown rise. Trim satellites 1–2% and pause fresh adds.

Isn’t hedging just “being wrong with extra steps”?

No. A 10–30% index hedge is a time-buying device that caps net beta while you wait for undo conditions (spreads compress, |z|<1σ). Track carry; remove in stages as stress clears.

How do I size satellites without “hope”?

Vol-weighting: if an asset runs ~3× BTC volatility, its dollar size ≤⅓ of your BTC sleeve. Recompute monthly; never eyeball. Satellites ≤15% total, ≤5–6% per asset.

Should I calendar-rebalance or drift-rebalance?

Drift with bands (core ±7–10%, satellites ±5–7%) + persistence (2–3 checks). Use calendar windows only as a preference when liquidity is deep, not as a hard trigger.

When do I re-add risk after trimming?

Use a 3-stage ladder: re-add ⅓ when spreads < p85 and |z|<1σ for 24h, ⅓ lagi saat MSS <45, dan sisa ⅓ saat MSS <35. Core first, strongest satellite later, some satellites never return.

What’s the fastest way to lower execution cost?

Cap each slice ≤10% of visible depth within 5 bps, avoid top-decile spread periods, and TWAP over 30–90 minutes during deeper windows (e.g., US/EU overlap).

How do I prevent “alert fatigue”?

Bundle signals into stress packets and compute one Market Stress Score (0–100). Require persistence (≥3 checks). Router maps “one packet → one action” with a pre-written undo rule.

What if data feeds glitch during volatility?

Data-quality sentinel: block actions if freshness, cohesion, or coverage fail. Router drops to Watch state only and pages on-call. Never trade on forward-filled data >5 minutes.

How do I prove this process actually helps?

Shadow-mode 30 hari: jalankan router di kertas, log biaya eksekusi, dan bandingkan MDD/CVaR vs baseline. Lalu pilot kecil, tingkatkan setelah empat minggu log match ekspektasi.

Conclusion: Process Over Prediction

Bear markets don’t reward genius; they reward process. Fund life first, wire simple risk rails to measurable signals, and keep a paper trail of every action and undo. With runway + bands + MSS + execution hygiene, you stop donating edge to spreads and start compounding small, boring wins month after month.

If you adopt only three changes today: (1) set a cash floor and automate refills, (2) implement a single composite stress score with persistence, and (3) cap each order at ≤10% of depth within 5 bps. Your drawdown curve—and your sleep—will change faster than your opinions.
