 Cross-field comparison (second example above) enables golden cross / death cross detection without needing a value on the right-hand side.
 
+### Symbol Discovery
+
+Use `search_symbols` to find exact TradingView identifiers before screening:
+
+```json
+// Search for Apple
+{ "query": "apple" }
+
+// Narrow by exchange and type
+{ "query": "bitcoin", "exchange": "BINANCE", "asset_type": "crypto" }
+```
+
+Returns normalized symbols with exchange, type, and currency.
+
+### Market Metainfo
+
+Use `get_market_metainfo` to discover available fields for a market:
+
+```json
+// All fields for US stocks
+{ "market": "america" }
+
+// Specific fields only
+{ "market": "america", "fields": ["name", "close", "market_cap_basic"] }
+
+// Raw passthrough for debugging
+{ "market": "america", "mode": "raw" }
+```
+
+### Technical Analysis Summary
+
+Use `get_ta_summary` for TradingView-style buy/sell/neutral labels:
+
+```json
+// Single symbol, default timeframes (60m, 4H, 1D, 1W)
+{ "symbols": ["NASDAQ:AAPL"] }
+
+// Multiple symbols with custom timeframes
+{ "symbols": ["NASDAQ:AAPL", "NASDAQ:NVDA"], "timeframes": ["60", "240", "1D", "1W"] }
+```
+
+Returns labels (`strong_buy`, `buy`, `neutral`, `sell`, `strong_sell`) plus raw scores based on oscillators and moving averages.
+
+### TA Ranking
+
+Use `rank_by_ta` to compare symbols by weighted technical alignment:
+
+```json
+// Equal-weight ranking
+{ "symbols": ["NASDAQ:AAPL", "NASDAQ:MSFT", "NASDAQ:NVDA"] }
+
+// Weight daily timeframe 3x more
+{ "symbols": ["NASDAQ:AAPL", "NASDAQ:MSFT"], "weights": { "1D": 3, "1W": 2 } }
+```
+
+Returns ranked list with per-timeframe breakdown and weighted average score.
