// Revision:        1
// Author:          @millerrh
// Strategy:  Enter long when recent swing high breaks out, using recent swing low as stop level.  Move stops up as higher lows print to act
// as trailing stops.  Ride trend as long as it is there and the higher lows aren't breached.  
// The difference between this one and the previous Breakout Trend Follower is that this one uses higher timeframe higher highs/higher lows as a filter instead 
// of an arbitrary Moving Average.  I wanted to test out whether waiting for longer term actual trend changes produced better stats than just the moving average.
// Conditions/Variables 
//    1. Manually configure which dates to back test
//    2. Can add a filter to only take setups that are above (or below for shorts) user-defined larger timeframe trends (helps avoid trading counter trend)
