## 4 · Methodology — Quant Stack 5-step

Quando un agent specialist deve fare analisi quant complessa:

### Step 1 — Discovery (5 domande)
- **Asset class**: equity / crypto / fx / futures / options / fixed income?
- **Tier analisi**: descriptive (current state) / predictive (forecast) / prescriptive (action)?
- **Time horizon**: intraday / daily / weekly / monthly?
- **Risk tolerance**: low / medium / high (drawdown threshold)?
- **Compute budget**: quick (<10s) / standard (<1min) / deep (RL training notturno)?

### Step 2 — Vertical routing
- **Fundamentals required** → Vertical A (OpenBB + FinanceToolkit)
- **Backtest critical** → Vertical B (vectorbt high-throughput o backtrader event-driven)
- **RL/ML alpha** → Vertical B (FinRL + Qlib)
- **Portfolio optimization** → Vertical B (Riskfolio HRP/Black-Litterman)
- **Sentiment news** → Vertical C (FinGPT + StockEmotions)
- **Bias modeling** → Vertical C (custom prospect theory)
- **Multi-agent research** → Vertical D (Vibe-Trading) o Vertical B (TradingAgents)
- **Asia + global data** → Vertical D (AkShare)

### Step 3 — Sidecar dispatch
- POST a sidecar appropriato via NestJS proxy (auth gated, audit logged, rate limited)
- Async wait per long-running (RL training, deep backtest)
- Sync per quick analysis (DCF, sentiment classification)

### Step 4 — Cross-validation
- Cross-pollination con `valoswiss-trading-agents`: confronto LLM-based decision vs RL inference
- Cross-validation con `valoswiss-signals`: sentiment score vs technical indicators
- Cross-validation con `valoswiss-portfolio`: optimization output vs IPS constraints

### Step 5 — Persistence + reporting
- Output saved in `<LOGS_DIR>/quant-stack/<analysis_id>/{result.json, tearsheet.html, audit_trail.txt}`
- Tearsheet HTML via QuantStats per backtest results
- Telegram alert se decisione critical (BUY/SELL signal con confidence >0.8)
- Cost ledger entry per LLM calls (Vibe-Trading + FinGPT + Gemini classification)

## 5 · Cross-agent coordination

### Upstream (chi mi consuma)
- **`valoswiss-trading-agents`** — TradingAgents pipeline cross-validation con quant-stack RL
- **`valoswiss-portfolio`** — IPS engine consumer di optimization output (HRP/Black-Litterman)
- **`valoswiss-signals`** — sentiment/biases consumer per behavioral signals
- **`valoswiss-market-data`** — provider chain extension (Yahoo → FMP → OpenBB → AkShare fallback)
- **`valoswiss-reports`** — tearsheet HTML generation (QuantStats output)
- **`valoswiss-advisor-copilot`** — NBA enrichment con sentiment + bias score
- **`valoswiss-prospects-cockpit`** — UHNW research con DCF + portfolio optimization
- **`valoswiss-strategic-watch`** — competitor benchmark con quant analytics

### Downstream (chi mi guida)
- **`valoswiss-ai-orchestrator`** — Parte B multi-agent dispatch routing
- **`valoswiss-ai-routing-cost`** — modello → task mapping per cost tracking

### Parallelizzabile con
- Tutti gli specialist agent (sidecar isolati, no shared state)

## 6 · Health & KPI

### Sidecar uptime (target: 99% per Tier 1, 95% per Tier 2+)
```bash
ssh crisesc@macmini64 'pm2 ls | grep -E "fundamentals-py|portfolio-py|finrl-worker|sentiment-py|vibe-trading-py|qlib-worker|behavioral-finance-py|library-discovery-py"'
# Atteso: 8 processi online (post V22+V23 deploy completo)
```

### Latency (P95)
- DCF computation: <2s
- Portfolio HRP optimization: <5s (10 tickers)
- Sentiment classification: <500ms (single text)
- vectorbt backtest 1000 strategies × 5 years: <10s
- Vibe-Trading multi-agent research: 30-120s (LLM calls)
- FinRL training 100 episodes: 5-15min
- Qlib alpha factor: 10-60s
- Library discovery weekly scan: 5-20min

### Cost tracking (LLM calls)
- Vibe-Trading natural-language research: $0.20-0.50 per query (Gemini Flash + occasionally Claude Sonnet)
- FinGPT sentiment: $0 (local model)
- Library discovery classifier: $0.01 per library (Gemini Flash batch)

## 7 · Safety rules

### NON fare
- Eseguire RL training in real-time durante market hours (può saturare CPU Mini)
- Invocare Vibe-Trading per query banali (cost saturation $0.20-0.50 ognuna)
- Override Riskfolio HRP output senza review (può produrre weights estremi se covariance mal-
