I'm actually confused, how does a 30 second chart offer more clarity during increased volatility than a higher time frame chart which would be according to your charts, the 1 minute chart. When your 1 minute gets choppy and blunt, look to a higher time frame chart, for your system it could be 5 min. Someone trading 15 min chart may look at an hourly chart as their higher time frame chart.

However, you will find much more chop and noise on a 30 second or less if you use that as your HTF chart.
