Trading systems based on fast moving averages are quite easy to follow. Let's take a look at this simple system.
Currency pairs: ANY
Time frame chart: 1 hour or 15 minute chart.
Indicators: 10 EMA, 25 EMA, 50 EMA.
Entry rules: When 10 EMA goes through 25 EMA and continues through 50 EMA, BUY/SELL in the direction of 10 EMA once it clearly makes it through 50 EMA. (Just wait for the current price bar to close on the opposite site of 50 EMA. This waiting helps to avoid false signals).
Exit rules: option1: exit when 10 EMA crosses 25 EMA again.
option2: exit when 10 EMA returns and touches 50 EMA (again it is suggested to wait until the current price bar after so called “touch” has been closed on the opposite side of 50 EMA).
Advantages: it is easy to use, and it gives very good results when the market is trending, during big price break-outs and big price moves.
Disadvantages: Fast moving average indicator is a follow-up indicator or it is also called a lagging indicator, which means it does not predict future market directions, but rather reflects current situation on the market. This characteristic makes it vulnerable:
firstly, because it can change its signals any time, secondly – because need to watch it all the time; and finally, when market trades sideways (no trend) with very little fluctuation in price it can give many false signals, so it is not suggested to use it during such periods.
2. Parabolic Sar and ADX
The two indicators we are going to talk about here are found to be very well working when used side by side. This Forex trading system is an another simple discovery; and hundreds of such discoveries can be made when traders are there to learn and experiment.
Any currency pair and time frame can be used.
Indicators: Parabolic SAR default settings (0.02, 0.2), ADX 50 (with +DI, -DI lines)
Entry rules: SELL When the +DI line is below the -DI line, and Parabolic SAR gives sell signal. When the +DI line is above the -DI line, all Parabolic sell signals must be ignored.
Entry rules: BUY when the +DI line is above the -DI line, and Parabolic SAR gives buy signal. When the +DI line is below the -DI line, all Parabolic buy signals must be ignored.
Exit rules: when +DI line and -DI lines have crossed again.
Advantages: allows filtering entries and predicting good exits.
Disadvantages: Both Parabolic SAR and ADX are follow-up indicators. Although they complement each other very effectively, the “weakest” in chain is ADX, because during trading it can give one signal, but later change to the opposite. Once given a signal from ADX, waiting for the current price bar to close to avoid such misleading is advised.
