DOUBLE TRIPLE IMPORTANT CHANGE. AGAIN. yes again. As of June 26, 2018 I am REMOVING BOTH THE 1000 PERIOD LOOKBACK TREND FILTER AND THE STDEV 1.1 FILTER. After careful consideration, I feel that stdev was being calculated in real time on the actual entry bar, and may be the reason why so many backtest trades were not duplicated in the real world. After I removed lookahead bias (including the current entry bar in lookback trend calculation), the advantage of the 1000 bar lookback was gone - however... the max drawdown is still lower, so it may be worth offering this as an option.

I wanted to compare our current drawdown to the worst drawdown in the backtesting data, just to get an idea of what could happen... not to say that this WILL happen, but it's prudent to be aware and prepared.
