I was watching them a bit on my oanda account and I dont see what kind of information you could glean from it.
No, they are a waste of time.
Trading that would be a nightmare.
An emotional roller coast ride like no other.
Would be way better off trading tick charts
IF your a scalper, I personally think they are beneficial, as you can see the price break at YOUR intended trade target area.
If its ranging, its very very nice to use.
And it dont look at the bars, I sync them together, and black them out, and just follow the price action comparable movements from, 5 to 10 seconds.
Its really a personal preference, and what your style is in the end…
