Reading of RSI is between value 35-45 and 75-85 in the rising market and reading of RSI is between value 20-30 and 55-65 in the falling market. J. Welles Widler recommended setting a period of 14 days for analysis but now other time periods have also become popular. Traders and investors must follow some rules for making a long or short entry. For long entry, RSI (14) must move below 40 and move back above 30. MA (50) must be more than MA (200). For short entry, RSI must move above 70 and move back above 70. MA (50) must be less than MA (200).
