Thanks for sharing that. That looks like the sort of purely directional downtrend day which is now, due to non-human traders I believe, quite rare, contrary to Al Brooks' trading teachings.
The institutional computer-based trading downtrend days can often have bull traps to the upside at the open, as well as all sorts of failed countertrend breakouts to the VWAP and above the 20-period EMA prior to resumption of the overall trend, making holding a contract all day for a large swing reward quite a psychologically and financially difficult task.
