# Crypto Radar
|
||||
|
||||
Marktanalyse dashboard voor Kraken — toont top 6 tradeable assets op basis van
|
||||
technische analyse + nieuws sentiment.
|
||||
|
||||
## Vereisten
|
||||
|
||||
- Docker + docker-compose
|
||||
- Traefik + Authentik draaien als `traefik-proxy` network
|
||||
- Kraken account met API keys
|
||||
- CryptoPanic API key (gratis)
|
||||
|
||||
## Setup
|
||||
|
||||
```bash
|
||||
# 1. Clone / kopieer de map
|
||||
cp .env.example .env
|
||||
|
||||
# 2. Vul .env in met jouw keys
|
||||
|
||||
# 3. Start
|
||||
docker-compose up -d
|
||||
|
||||
# Dashboard bereikbaar op: https://crypto.jouwdomein.nl
|
||||
# API bereikbaar op: https://crypto-api.jouwdomein.nl
|
||||
```
|
||||
|
||||
## API endpoints
|
||||
|
||||
| Endpoint | Beschrijving |
|
||||
|---|---|
|
||||
| `GET /api/assets/ranked` | Top 6 ranked assets (gecached 60s) |
|
||||
| `GET /api/assets/{symbol}` | Detail + candles voor één asset |
|
||||
| `GET /api/news/{coin}` | Nieuws + sentiment voor één coin |
|
||||
| `GET /api/health` | Health check |
|
||||
|
||||

|
||||
|
||||
## Indicatoren gebruikt
|
||||
|
||||
- **RSI (14)** — koopzone detecitie (40-55)
|
||||
- **EMA 9/21/50** — trend richting en crossover
|
||||
- **VWAP** — prijs vs. institutioneel gemiddelde
|
||||
- **Bollinger Bands (20, 2σ)** — volatiliteitsregime
|
||||
- **ATR (14)** — volatiliteitsfilter (>5% = skip)
|
||||
- **Volume ratio** — bevestiging van beweging
|
||||
|
||||
## Volgende stap
|
||||
|
||||
De trading bot zelf (order execution, DCA-in logica, R:R management)
|
||||
is bewust nog niet ingebouwd. Valideer eerst de signalen via dit dashboard
|
||||
voordat je live orders plaatst.
