How this service works
Daily Relative Strength Index (RSI) momentum indicator for US-listed equities and ETFs. Returns the current RSI value (0-100), an oversold/neutral/overbought trading signal, and the last daily close. Useful for technical analysis, momentum signals, mean-reversion strategies, market timing, swing trading, and AI-driven trading agents. Configurable lookback period (2-100 trading days, default 14). Daily close data from Alpaca Markets.
Output
Returns a JSON object with the ticker symbol, RSI value (0-100), a trading signal (oversold/neutral/overbought), last daily close price, the lookback period used, number of closes used in the calculation, and a UTC timestamp of when the data was fetched.
Example use cases
Check overbought ETF before selling
“Before I consider taking profits on my SPY position, can you pull the current RSI signal — is it overbought right now or still in neutral territory?”
Scan for oversold swing trade entry
“I'm looking for a potential swing trade entry on TSLA — what's the RSI right now and does it look oversold on a 14-day basis?”
Mean reversion signal for MSFT
“I want to check if MSFT has pulled back enough to be a mean-reversion buy — what's its current RSI value and what signal is it showing?”
