The best way to learn technical analysis is to fire up a demo account and practice day trading on charts.
Start by setting your chart to a 1-minute, 5-minute, or 15-minute timeframe. Then use simple candlesticks to visualize any price action.
Begin with one or two indicators, such as moving averages (a combination of short-term like a 9-period, and long-term like a 50-period to help identify trends) and the relative strength index (to spot overbought and oversold levels).
Volume indicators are also helpful for confirming price movements, while Bollinger Bands can assist in identifying volatility and potential reversals.
