The Guppy trading system AFL for Amibroker with Buy Sell signal

This trading system was developed by Australian trader Daryl Guppy and named after him. He had used a set of twelve exponentially-weighted moving averages.  He had selected 3, 5, 8, 10, 12, and 18 period exponentially-weighted moving averages ( EMA)  as short-term and 30, 35, 40, 45, 50, and 60 as long term EMA. This helps a trader to analyze the stock from different levels.

There are many ways to deploy this system, but rather than seeing this system as a cross over trading system we should view it as a trend momentum identifier. What has been suggested by Guppy is to take the sum of six short-term EMAs against the sum of the six long-term EMAs and look for trading signals.

3/15 Crossover Trading AFL with buy sell signals

This trading system is based moving average cross over. The importance is given for the Three days moving average and the Fifteen days moving average. This method produces some good trades on a weekly time frame. Even on EOD basis this could generate good signals. But on intraday it can produce many whipsaw like patterns leaving the user in a confused state.  When a 3 day MA crosses the 15 days MA a trading signal is generated. It can be long or short. If the user identifies good stocks and applies this system some good trades can be done. The only condition is the system should be followed with discipline.

The system indicates support level and resistance levels based on the previous candles. SAR also has been provided which alerts the user reversal trends at the levels. In the properties windows the support and resistant levels can be adjusted and the desired colors too can be set. An audio alert is also incorporated alerting the trader of buy sell signals.

I have added a magnified market price to this AFL which is also customizable, for easy viewing.
