Moving Average Convergence/Divergence(MACD)?
The Moving Average
Convergence/Divergence indicator is a momentum oscillator primarily used to
trade trends. Although it is an oscillator, it is not typically used to
identify over bought or oversold conditions. It appears on the chart as two
lines which oscillate without boundaries. The crossover of the two lines give
trading signals similar to a two moving average system.
KEY TAKEAWAYS
- The MACD line is calculated by subtracting the 26-period
exponential moving average (EMA) from the 12-period EMA. The MACD signal
line is a 9 period EMA of the MACD line.
- MACD is best used with daily periods, where the traditional
settings of 26/12/9 days is the norm.
- The MACD triggers technical signals when the MACD line crosses
above the signal line (to buy) or falls below (to sell) it.
- MACD can help gauge whether a security is overbought or oversold,
alerting traders to the strength of a directional move.
- MACD can also alert investors to a bullish/bearish divergence
(e.g., when a new high in price is not confirmed by a new high in the
MACD, and vice versa), suggesting a potential failure and reversal.
- After a signal line crossover, it is recommended to wait for 3-4
days to confirm that it is not a false move.
