Strategy and Decision Making
|
Making
trading decisions and developing a sound and effective trading
strategy is an important foundation of trading.
Before developing
a trading strategy, a trader should have a working knowledge
of technical analysis as well as knowledge of some of the
more popular technical studies. Please visit these pages
for detailed information.
Sample
Strategy 1 - Simple Moving Average
Successful
trading is often described as optimizing your risk with respect
to your reward, or upside. Any trading strategy
should have a disciplined method of limiting risk while making
the most out of favorable market moves. We will
illustrate one decision making model which uses a Simple Moving
Average ("SMA") technical study, based on a 12-period
SMA, where each period is 15 minutes. This is one example
of a trading decision making strategy, and we encourage any
trader to research other strategies as thoroughly as possible.
We
will use a simple algorithm: when the price of the currency
crosses above the 12-period SMA, it will be taken as a signal
to buy at the market. When the currency price crosses
below the 12-period SMA, it will be a signal to "Stop
and Reverse" ("SAR"). In other words,
a long position will be liquidated and a short position will
be established, both with market orders. Thus this system
will keep the traders "always in" the market - he
will always have either a long or short position after the
first signal. In the chart below, the white line represents
the price of USDJPY, the purple line represents the 12-period
SMA of USDJPY, and the red line indicates where USDJPY crosses
above the SMA, generating a buy signal at approximately 129.90:
This
is a simple example of technical analysis applied to trading.
Many strategies used by professional traders make use of moving
averages along with other indicators or "filters".
Note that the moving average method has an element of risk
control built in: a long position will be stopped out fairly
quickly in a falling market because the price will drop below
the SMA, generating a stop-and-reverse signal. The same
holds true for a sell signal in a rising market. Note
that the SMA is generated automatically by GCI's integrated
charting application.
Sample
Strategy 2 - Support and Resistance Levels
One
use of technical analysis, apart from technical studies, is
in deriving "support" and "resistance"
levels. The concept here is that the market will tend
to trade above its support levels and trade below its resistance
levels. If a support or resistance level is broken,
the market is then expected to follow through in that direction.
These levels are determined by analyzing the chart and assessing
where the market has encountered unbroken support or
resistance in the past.
For
example, in chart below EURUSD has established a resistance
level at approximately .9015. In other words, EURUSD
has risen up to .9015 repeatedly, but has been unable to move
beyond that point:
The trading strategy would
then be to sell EURUSD the next time it gets close to .9015,
with a stop placed just above .9015, say at .9025. This
would have indeed been a good trade as EURUSD proceeded to fall
sharply, without breaking the .9015 resistance. Hence
a substantial upside can be achieved while only risking 10 or
15 pips (.0010 or .0015 in EURUSD).
