# Signal — Bidbes Real-Time Market Intelligence

> Signal is a live financial market intelligence service from Bidbes covering gold, silver, USD, EUR, AED, GBP, Bitcoin and Tether. For each country × asset page it computes a BUY/SELL/HOLD assessment from real OHLC price history (RSI, MACD, EMA, Bollinger, ATR, pivots) plus a fundamental news score, then localizes the price into the correct currency for 14 countries — including real-time Iranian gold & FX data from the Tehran (TGJU) gold and currency network. Tradable setups additionally carry an executable trade plan (entry, stop-loss, two take-profits, invalidation rule), and a walk-forward backtest endpoint publishes the engine's measured evidence.

## Key facts

- Real-time market quotes across 8 assets: gold (XAU), silver (XAG), USD, EUR, AED, GBP, Bitcoin (BTC), Tether (USDT).
- Live OHLC candle history from Yahoo Finance, Binance and Kraken feeds price the technical engine.
- Technical indicators recomputed natively per timeframe (resampled candles): EMA 9/21, SMA 50/200, RSI-14, MACD, Bollinger Bands, ATR-14, pivot support/resistance, momentum, volatility.
- Signal model: combined score (-100..+100) of technical + fundamental news with horizon-adaptive weighting (short 60/40, medium 48/52, long 32/68); per-horizon entry thresholds (short 25, medium 20, long 15) plus per-asset offsets (crypto stricter, stablecoin effectively never directional) and a range-squeeze filter that demands extra conviction in chop zones.
- Reliability tiers: `tradable` (entry/SL/TP trade plan), `indicative` (directional view only), `informational` (corridor only, e.g. yearly horizons that 5 days of history cannot build).
- Trade plan on tradable non-HOLD signals: entry, stop-loss behind structure (S1/pivot, ATR-clamped), TP1 at 1.5R (bank half), TP2 runner at 2.5R with stop to breakeven, and a written invalidation rule.
- Walk-forward evidence: `GET /api/backtest` replays the current engine on past bars with the real two-stage exit and reports win rate, expectancy per trade (R), and W/L counts.
- Localized pricing for 14 markets: US, UK, Iran, China, Turkey, UAE, Saudi Arabia, Germany, France, Switzerland, India, Japan, Canada, Australia.
- Iran coverage reads the live TGJU (اتحادیه طلا و ارز تهران) network: gram 18, mesghal, coins (Emami, Bahar, Nim, Rob), silver 999, USD/EUR/AED/GBP in Tomans.
- Data integrity is surfaced honestly: freshness is reported as live vs recent; confidence/risk are degraded whenever candle history is thin, non-live, news is missing, technicals and fundamentals conflict, or the market is in a volatility squeeze — the engine returns HOLD instead of inventing a direction.

## Transparency & limitations

- Signals are algorithmic market intelligence for informational purposes, NOT guaranteed financial advice. Markets carry risk; measured technical-only expectancy is approximately breakeven, so disciplined risk management (fixed fractional risk, always a stop-loss) is essential.
- A directional BUY/SELL signal is only emitted when real candle history exists (>=50 candles) and the timeframe has analyzable structure; otherwise the engine returns HOLD with flags such as `no-real-history` or `insufficient-history-for-horizon`.
