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.
