RSI Overbought and Oversold Levels with Threshold Signals

Summary

This document presents the Relative Strength Index as an oscillator for interpreting momentum extremes. It uses a 14-period length by default and allows the input price series to be selected. The conventional guideposts are 70 for an overbought reading and 30 for an oversold reading, with a middle reference at 50. The plotted indicator marks threshold events and uses the 70 and 30 levels as its signal boundaries.

The included strategy logic enters long when RSI crosses into the overbought region and short when it crosses into the oversold region, which reverses the common interpretation of these extremes as potential reversal zones. The accompanying backtest setup specifies BTC/USDT futures and a short historical window, but reports no outcomes. RSI thresholds alone do not establish whether a market will reverse or continue, and the document offers no additional trend filter, exit plan, or risk controls.

Key ideas

• The indicator calculates RSI from a selectable price source and period.
• Readings at or above 70 are conventionally treated as overbought, while readings at or below 30 are oversold.
• The script marks crossings of the upper and lower threshold levels.
• Its entry logic buys on an overbought crossing and sells short on an oversold crossing.
• The published backtest configuration contains no performance evaluation.
