Learning to read charts and interpret basic technical indicators is essential for anyone wanting to trade or invest in the financial market. Below, I explain the main concepts and indicators:
1. Types of Charts
Line Chart: Shows only the closing price over time. It is simple, but limited.
Bar Chart: Shows open, high, low, and close (OHLC).
Candlestick Chart: More commonly used by traders, also shows OHLC, but with a more intuitive visual.
2. Main Technical Indicators
RSI (Relative Strength Index)
Measures the strength of price movement.
Scale of 0 to 100.
Above 70: overbought asset (may drop).
Below 30: oversold asset (may rise).
Useful for identifying reversals.
MACD (Moving Average Convergence Divergence)
Shows the relationship between two moving averages (usually 12 and 26 periods).
Composed of:
MACD Line.
Signal Line (usually 9 periods).
Histogram (difference between MACD and signal line).
Common signals:
MACD line crossing above the signal line = buy.
Crossing below = sell.
Moving Averages
Smooth prices to identify trends.
Simple Moving Average (SMA): arithmetic average of prices.
Exponential Moving Average (EMA): gives more weight to recent prices.
Signals:
Price above the average: uptrend.
Short-term crossing above the long-term average (e.g., EMA 9 crossing above EMA 21) = buy signal.
3. How to start practicing
