OPEN-SOURCE SCRIPT
RSI Overbought Oversold Alert
█ OVERVIEW
A clean RSI indicator with overbought/oversold alerts that fire only once per crossing — not repeatedly while price stays in the zone.
Built to fix a common frustration: TradingView's default RSI alert keeps firing every bar while RSI stays above or below the threshold. This script uses crossover/crossunder detection so you get notified at the moment RSI crosses the level, and nothing more until it crosses again.
█ FEATURES
● Customizable overbought and oversold levels (default 70/30)
● Alerts trigger only on the crossing bar, not throughout the zone
● MA overlay on RSI (SMA, EMA, SMMA/RMA, WMA, VWMA)
● MA crossover alerts included
● Color-coded overbought, oversold, and middle zones
● All colors fully customizable
█ ALERTS (4 types)
- RSI Overbought Alert — RSI crosses above the overbought level
- RSI Oversold Alert — RSI crosses below the oversold level
- RSI Crossed Above MA — RSI crosses above its moving average
- RSI Crossed Below MA — RSI crosses below its moving average
█ RECOMMENDED ALERT SETTING
When creating an alert, set the frequency to "Once Per Bar Close."
This ensures the alert fires once per confirmed bar, not on every tick.
