Frequently Asked Questions

How do I choose the right period length for indicators?

The optimal period depends on your trading timeframe. Shorter periods (5-20) are better for short-term trading, while longer periods (20-50) suit long-term analysis.

What's the difference between RSI and MACD?

RSI measures speed of price movements while MACD (Moving Average Convergence Divergence) shows the relationship between two moving averages.

Can these indicators predict future prices?

While indicators can identify trends and potential reversals, they don't predict future prices with certainty. Always use them with other analysis methods.
