What are the numbers in MACD representing, for example (12,26,9) MACD: +1.23

The numbers in the MACD (Moving Average Convergence Divergence) indicator represent the settings used for calculating the MACD line and the signal line.

1. The first number (12) is the number of periods used to calculate the faster-moving average (MACD line).

2. The second number (26) is the number of periods used to calculate the slower-moving average (longer EMA).

3. The third number (9) is the number of periods used to calculate the moving average of the difference between the faster and slower moving averages (MACD histogram).

In the example you provided, (12,26,9) MACD: +1.23, the MACD line is calculated by subtracting the 26-period EMA from the 12-period EMA. The result is the MACD line. The signal line is then calculated by taking a 9-period EMA of the MACD line. The value of +1.23 indicates that the MACD line is positive and above its signal line, which can be interpreted as a bullish signal.
