Relative Strength Index (RSI)
Momentum oscillator that measures the magnitude of recent price changes on a 0–100 scale.
RSI is calculated by comparing average gains to average losses over a lookback period — most commonly 14 bars. The result oscillates between 0 and 100. Readings above 70 are conventionally called overbought; below 30, oversold.
In strong trending markets, RSI can stay pinned above 70 or below 30 for extended periods. The actionable signal is rarely the absolute level — it is divergence (price prints a higher high while RSI prints a lower high) or a failure swing.
JR TradeHub computes RSI(14) from live tick history per symbol and uses it as one input into the BUY / SELL / HOLD signal.
