If your intent is to continue to use ONLY TrendDirection for a Trend Following system, I do believe this could be pretty much it.
Another way to improve the signal timing and to avoid short term wip-saw Buy/Sell signals is to define an "Out Of Market" condition, or equivalently to define an exit signal for each entry (i.e. LE=Long Entry paired with LX=Long Exit; similar for short trades).
For the "zoomed in" chart, I am pretty positive that an indicator like a "Smoothed RSI" or an MACD-Histogram would have identified a Bullish Divergence in that time segment that could be used as a Buy Entry signal or as a Hold signal.
I hope I am "on the money" with my comments.
