RSI (14)
14-period relative strength index.
What it measures
The 14-period relative strength index (Wilder, 1978): average gain versus average loss, mapped to [0, 100]. In this category the window axis selects the timeframe the indicator is computed on — rsi_14@1h is RSI on hourly bars, rsi_14@5m on five-minute bars — every value point-in-time. It is served not because RSI is exotic but because so much flow watches it: levels the crowd treats as oversold or overbought become coordination points worth knowing about.

Point-in-time, leak-free
Like every QUANT_API feature, technicals.rsi_14 is computed point-in-time: each value uses only data that had actually arrived at the timestamp you query — live or historical. No restatements, no backfills that quietly rewrite the past, no look-ahead. The value your backtest sees at a given stamp is the value the live API would have returned at that stamp. How we enforce this is documented on the methodology page.
Windows & transforms
The signal is computed over rolling windows; each window can be served raw or through a transform (z-score, percentile rank, delta…). Which windows and transforms you can query depends on your plan — the signal itself supports:
