Answer to the locked strategy... Formerly "High-Low Trader" .. Changed the name to Edge Trail Trader to delineate from the locked version, which is no different. You can add this one to your favorites now.
Similar to SuperTrend or the ATR trailing stop lines that are common-place in chart indicator circles, the B3 High-Low Trail-Trader works as a back-break line to flip binary long and short biasing. Here is the strategy set to 7 bars back. You can find this style of trading system in several books, and there are many ways to come to the trailing stop line, so I imagine the bars back length can be slid around to suit certain charts. This happens to be my favorite trailing line.
