--- name: signal-engine-production-d88d.up.railway.app description: signal-engine-production-d88d.up.railway.app provides discrete, single-shot trading signals for four crypto assets (BTC, ETH, SOL, DOGE) across four distinct technical strategies: VWAP reversion, EMA 5 breakout, RSI reversion swing, and RSI 7 extremes. Each signal response includes direction (long/short/null), a confidence score, take-profit and stop-loss percentages, hold time, and a reasoning string. The host does not execute trades, stream prices, or support assets outside the four listed symbols. host: signal-engine-production-d88d.up.railway.app --- # signal-engine-production-d88d.up.railway.app This host is a signal-generation engine for short-to-medium-term crypto trading decisions. It serves agents that need structured, parameterized trade signals before placing or evaluating a position. Each strategy is accessed via a dedicated skill that accepts a strategy_id and symbol, returning a self-contained signal payload. The four strategies cover mean-reversion (VWAP, RSI swing), momentum extremes (RSI 7), and trend-following breakout (EMA 5), giving agents access to complementary signal types from a single host. ## When to use this host Use this host when an agent needs a structured, single-shot trade signal with explicit TP/SL and hold-time parameters for BTC, ETH, SOL, or DOGE. It is appropriate for pre-trade decision logic, signal comparison across strategies, and confidence-gated execution workflows. Do not use this host for: assets outside BTC, ETH, SOL, DOGE; fused multi-strategy signals (the skills hint at a /v1/signal/{symbol} endpoint that may exist separately on the same host but is not exposed here); continuous or streaming price data; historical signal lookups; or order execution. For price feeds and OHLCV data, route to a dedicated market-data host. For order placement, route to a brokerage or DEX execution host. ## Capabilities ### VWAP Reversion Signals Returns mean-reversion trade signals based on VWAP deviation for BTC, ETH, SOL, or DOGE, including direction, confidence score, TP/SL percentages, hold time, and reasoning. - **`fetch-vwap-reversion-signal`** — Returns a live VWAP reversion trading signal for BTC, ETH, SOL, or DOGE, including direction (long/short), confidence score, take-profit/stop-loss percentages, hold time, and reasoning. ### EMA 5 Breakout Signals Returns short-term directional breakout signals based on EMA 5 logic for BTC, ETH, SOL, or DOGE, including entry confidence, TP/SL levels, and recommended hold duration. - **`fetch-ema5-breakout-signal`** — Returns the current EMA 5 breakout trading signal (long/short/null) with stop-loss, take-profit, hold time, and reasoning for a given crypto asset. ### RSI Reversion Swing Signals Returns swing trade signals based on RSI reversion logic for BTC, ETH, SOL, or DOGE, including entry direction, confidence score, TP/SL targets, hold time, and human-readable rationale. - **`fetch-rsi-reversion-swing-signal`** — Returns an arena trading signal for the RSI reversion swing strategy on a given crypto asset, including signal direction, score, stop-loss, take-profit, and hold time when a signal is present. ### RSI 7 Extremes Signals Returns discrete trade signals based on RSI 7 extreme readings for BTC, ETH, SOL, or DOGE, including score, stop-loss, take-profit, and hold time when a signal is present. - **`fetch-rsi7-extremes-signal`** — Returns an RSI 7 extremes trading signal (long/short/null) for a supported crypto asset, including score, stop-loss, take-profit, and hold time when a signal is present. ## Workflows ### Multi-Strategy Signal Consensus *Use when an agent needs to evaluate whether multiple independent strategies agree on a directional trade for a single asset before committing to a position.* 1. **`fetch-vwap-reversion-signal`** — Fetch the VWAP reversion signal for the target asset to check mean-reversion bias and confidence score. 2. **`fetch-ema5-breakout-signal`** — Fetch the EMA 5 breakout signal for the same asset to check whether a directional breakout is also active. 3. **`fetch-rsi-reversion-swing-signal`** — Fetch the RSI reversion swing signal to add a third independent RSI-based directional read. 4. **`fetch-rsi7-extremes-signal`** — Fetch the RSI 7 extremes signal to check for extreme overbought/oversold conditions that confirm or contradict the consensus. ### Cross-Asset Strategy Scan *Use when an agent needs to identify which of the four supported assets currently has the strongest signal for a given strategy, in order to select the best trade candidate.* 1. **`fetch-ema5-breakout-signal`** — Fetch the EMA 5 breakout signal for each supported symbol (BTC, ETH, SOL, DOGE) sequentially to compare confidence scores and identify the highest-conviction breakout candidate. 2. **`fetch-rsi7-extremes-signal`** — Fetch the RSI 7 extremes signal for each symbol to cross-check which asset also shows an extreme RSI reading, narrowing the candidate list to assets with multi-signal confirmation. ## Skill reference ### `fetch-vwap-reversion-signal` **VWAP Reversion Signal** — Returns a VWAP reversion trading signal for a given crypto asset, including direction (long/short), confidence score, take-profit/stop-loss percentages, hold time, and reasoning. *Use when:* Use when an agent needs a short-term mean-reversion trade signal based on VWAP deviation for BTC, ETH, SOL, or DOGE, including entry direction, risk levels, and expected hold duration. *Not for:* Do not use for trend-following or breakout strategies; use ema_5_breakout or rsi_7_extremes strategy endpoints instead.
