dvcrn BTC Analyzer
Fetch real-time BTCUSDT candlestick data from Binance public REST API and compute a directional trading signal based on EMA20 slope and RSI14 momentum.
When to Use
- User asks: "analisa BTC sekarang"
- User asks: "BTC akan naik atau turun?"
- User asks: "berikan sinyal trading BTC 15 menit"
- User asks: "cek market BTC sekarang"
How It Works
This skill runs a local Python script that:
- Fetches 200 candles of BTCUSDT 15m OHLCV data from Binance public API (no API key needed).
- Computes EMA20 from closing prices.
- Computes RSI14 from closing prices.
- Determines direction based on: price vs EMA20, RSI level, and recent candle slope.
- Returns a strict JSON object with decision, confidence score, and reasoning.
Workflow
Step 1 — Run the analyzer script via bash tool: python3 ~/.npm-global/lib/node_modules/openclaw/skills/btc-analyzer/analyze.py
Step 2 — Parse the JSON output.
Step 3 — Present the result to the user clearly, including:
- Decision (UP / DOWN / SKIP)
- Confidence percentage
- Reason (EMA, RSI, slope context)
- Last close price
- Timestamp
Output Format
The script returns strict JSON: { "decision": "UP", "confidence": 72, "reason": "price above EMA20, RSI 58, bullish slope last 3 candles", "lastClose": 94500.00, "ema20": 94200.00, "rsi14": 58.3, "timestamp": "2026-02-23T00:00:00Z" }
Decision values:
- UP: bullish signal, consider long
- DOWN: bearish signal, consider short
- SKIP: no clear signal, stay out
Confidence range: 0-100 (higher = stronger signal)
Signal Logic
- RSI < 30: decision = UP (oversold)
- RSI > 70: decision = DOWN (overbought)
- Price > EMA20 AND slope up: decision = UP
- Price < EMA20 AND slope down: decision = DOWN
- Otherwise: decision = SKIP
Error Handling
If Binance API is unreachable or returns an error: {"decision":"SKIP","confidence":0,"reason":"API error or network issue","lastClose":0,"timestamp":""}
Guardrails
- Always run the script via bash tool — never fabricate or guess output values.
- Do not hardcode prices or decisions.
- If script fails, show the actual error message to the user.
- This skill uses Binance public API only — no API key or authentication required.
- Data is real-time; do not cache or reuse previous results.
