The
Uses in Forex Trading of Moving Averages
and MACD |

Moving
Averages: If you consider the "trend-is-your-friend"
statement of technical analysis as a true
sentence, the moving averages will be very
helpful. Moving averages tell the average
price in a given point of time over a defined
period of time. They are called moving because
they reflect the latest average, while adhering
to the same time measure.
A weakness of moving averages is that they
lag the market, so they do not necessarily
signal a change in trends. To address this
issue, using a shorter period, such as 5
or 10 day moving average, would be more
reflective of the recent price action than
the 40 or 150-day moving averages.
Alternatively, moving averages may be used
by combining two averages of distinct time-
frames. Whether using 5 and 20-day MA, or
40 and 150-day MA, buy signals are usually
detected when the shorter-term average crosses
above the longer-term average, i.e. price
will likely go up. Conversely, sell signals
are suggested when the shorter average falls
below the longer one, i.e. price will likely
go down.
There are three kind of mathematically distinct
moving averages: Simple MA; Linearly Weighted
MA; and Exponentially Smoothed. The latter
choice is the preferred one because it assigns
greater weight for the most recent data,
and considers data in the entire life of
the instrument making of it a more accurate
indicator.
MACD: Moving Average Convergence Divergence:
MACD is a more detailed method of using
moving averages to find trading signals
from price charts. Developed by Gerald Appel,
the MACD plots the difference between a
26-day exponential moving average and a
12-day exponential moving average. A 9-
day moving average is generally used as
a trigger line, meaning when the MACD crosses
below this trigger it is a bearish signal
and when it crosses above it, it's a bullish
signal, with the corresponding implications
for the currency's price in each particular
situation.
As with other studies, traders will look
to MACD studies to provide early signals
or divergences between market prices and
a technical indicator. If the MACD turns
positive and makes higher lows while prices
are still tanking, this could be a strong
buy signal. Conversely, if the MACD makes
lower highs while prices are making new
highs, this could be a strong bearish divergence
and a sell signal.
