Quote from whitster:
just for the record, i don't think declining volatility is a CAUSE of "trendless" markets, it is a RESULT of trendless markets...
I'll repeat...
It's a Hint for you to correlate it with the cause.
Volatility isn't the only hint...there's also market seasonal tendencies (patterns).
Simply, I intentionally did not mention any causes and its for him (elit) to do his research because I have discussed the causes here in the past at ET and so have other ET members.
The causes more often than not...occur the same time volatility is either rising or declining.
This repeats every trading day.
Therefore, I agree, volatility is not the cause...it is a symptom of the cause.
Regardless, if your a price action only trader (no indicators)...this is a great place to start (volatility analysis and market seasonal pattern analysis).
However, if your an indicator trader (ADX or whatever)...
Your still going to need to understand what causes trends and what causes sideways markets to prevent becoming too dependent upon an indicator.
