What is Oversold and Overbought?
Oversold (RSI < 30) means the stock has been heavily sold and may rebound. Overbought (RSI > 70) means it's been heavily bought and may correct. Not a guarantee — just a signal to watch.
Is RSI enough for buy/sell decisions?
No. RSI is just one indicator. Combine it with others (MACD, volume, support/resistance) and fundamental analysis. Never trade based on a single signal.
What's the best RSI period?
Default RSI is 14 days, the most commonly used. Shorter periods (7) are more sensitive but give more false signals. Longer periods (21) are smoother but slower to respond.
