Yes, I've tried them. Gomi has several indicators based on Delta Volume.
I'm a volume nut so I've tried all of his.
I've even customized some of them to the way I like them.
The most significant thing in his indicators (IMO) is the ability to record and save the data. Unlike most 'live only' indicators, it can use recorded data to show price action / volume during replay or static viewing.
The only problem I see with Delta Volume is that many times it does not mean anything.
(Or at least it does not mean anything to me.)
I think it could be valuable in some cases but it seems like more information or a confirming indicator is necessary.
But that is JMO and what the heck do I know.

This is just my opinion but the only advantage I see in using mathematical calculations to determine S/R levels in advance is for automated strategies. If you're doing things manually then why not just mark off horizontal lines on the S/R pivots?
I do not believe on automated strategies. I know that nothing is better than human brain. It is quick and more reliable with continuous change conditions during live run of markets. As all markets run by humans. So Fib. is best tool to judge their behaviour/physiocology. I try to calculate all possible support and resistance levels mannullay by using Fib retracement, Fib extensions and Elliotwave movements once I find a good level with these tools, then this level gets more strength if supported by some mathematical levels like MML, IB Range,Sq9, and further confirmation about trade setups come from VPA and Price behaviour. Most of my trade setups are based on retest of those levels. This provides me Low risk Trade opertunities.
