Update of Average True Range Trailing Stops Strategy by HPotter to include backtesting support
Opens longs when price crosses over trailing stop line, closes when price crosses below
Option to open/close shorts when longs are closed/opened
Option to specify a time range to test over. For example, set Max Days Back to 360 and Min Days Back to 180 to test from 1 year ago to 6 months ago. To test the entire range of data, set both to 0.
