Crypto One-Way Market#

Overview#

Use this skill to fetch public crypto candle data, compute directional trend metrics, and decide whether price action is a one-way market ( 单边上涨 / 单边下跌) or a range/choppy market.

Default to the bundled script for repeatable calculations:

bash

python3 scripts/fetch_and_classify.py --symbol BTCUSDT --interval 15m --limit 200

Workflow#

1. Clarify the symbol, timeframe, and lookback if missing. Default to BTCUSDT, 15m, and 200 candles for intraday checks.
2. Run scripts/fetch_and_classify.py to fetch candles and compute the classification.
3. Read references/methodology.md when explaining thresholds, edge cases, or if the result is borderline.
4. Summarize direction, confidence, key evidence, and invalidation conditions. Avoid financial advice wording; present the result as market-structure analysis, not a trade instruction.

Data Fetching#

The script uses Binance public REST klines by default and needs no API key:

bash

python3 scripts/fetch_and_classify.py \
  --symbol ETHUSDT \
  --interval 1h \
  --limit 240

Useful options:

bash

--market spot
--market futures
--base-url https://api.binance.us
--json
--output candles.csv

If Binance is blocked or unstable, ask the user for an accessible exchange/API endpoint or use --base-url when they have a working Binance-compatible mirror.

Interpretation Rules#

Treat a one-way market as a move with persistent direction, high trend efficiency, limited counter-trend retracement, and enough volatility-adjusted distance from the start.

Report one of:

• bullish_one_way: likely 单边上涨.
• bearish_one_way: likely 单边下跌.
• weak_trend: directional but not clean enough to call one-way.
• range_or_chop: no strong one-way evidence.

In the final answer, include:

• Symbol, exchange source, interval, candle count, and time span.
• Classification and confidence.
• Directional return, trend efficiency, ADX, ATR-normalized move, max pullback, moving-average slope agreement.
• A concise explanation in Chinese when the user asks in Chinese.

Risk Notes#

Crypto data can have exchange outages, API regional restrictions, and sudden regime shifts. Never claim certainty. For live trading contexts, mention that low-liquidity symbols, news events, and funding/contract basis can invalidate candle-only signals.
