Notice in the Energen Corp. chart once a signal is generated the stock tends to pause or even retrace somewhat.
You can use the entry signal as an area of resistance or support depending on the trend of the stock.
For example, if a buy signal is triggered wait for the stock to retrace to the lower band of the moving average channel. Once it touches the band and reverses, you can enter a low risk buy position.
The opposite works with a sell signal.
Once the sell signal is generated, wait for the stock to trade to the upper band of the moving average channel. After the stock reverses, you can enter a low risk sell position.
