The Relative Strength Index (RSI) is a potent tool in a trader’s arsenal, used to gauge the momentum and possible reversal points of market trends. RSI backtesting is the process by which traders use historical data to assess and refine their RSI-driven trading strategies. Understanding the nuances of RSI and backtesting is paramount for traders aiming to craft strategies that withstand the test of time.
