// Past performance does not ensure future results.  This strategy provided with absolutely no warranty and is for educational purposes only

// The goal of this strategy is to enter a long position using the Custom Alert condition feature of LuxAlgo® Signals & Overlays™ indicator
// To trigger an exit from the long position, use one or more of the common exit signals which the Signals & Overlays™ indicator provides.
// You will need to connect those signals to this strategy in the dialog box.  
// We're calling this a "piggyback" strategy because the LuxAlgo® Signals & Overlays indicator must be present, and remain on the chart.
