Crypto technical indicators

Technical indicators for one perpetual computed deterministically from Hyperliquid candles: RSI(14), MACD(12,26,9) with signal and histogram, EMA 20/50/200, SMA 20/50, Bollinger(20,2) with bandwidth and %B, ATR(14) and window VWAP. Returns the latest value of each, the last N series points (points, max 100), and a plain summary (trend vs EMA50, RSI zone, MACD cross on the latest bar). interval 1m to 1M, limit = candles used (default 200, max 500). Choose a subset with indicators. No key, no LLM.
