Hi BS12,
Sorry to intrude in this excellent journal, I know I am not a regular contributor.
But I'm interested as to what you mean by "noise".
A term often thrown around, it gives the impression that some trading activity is not "signal", i.e it is insignificant.
This is not a concept with which I agree as I believe that all trading activity is important, both low and high volume. Every print tells a story and helps unravel the intent and psychology behind both large and small players, pros and amateurs alike.
e.g it can be just as useful to see where professional money has chosen to withdraw interest as to see where they are keen to do business. Often weak hands will be allowed, even encouraged, to move price on low volume in order to create a more favourable entry for the pros at no cost or risk to themselves.
The believer in the "noise" concept may just see a candle on low volume and think it insignificant. But the context behind this candle could be key to likely future price movement.
At other times they may not be so obedient and it takes a bunch of volume to persuade them to follow the pros' chosen course. But I digress.
I realise noise may simply be your chosen term for price movement, perhaps a spike, that is likely to take out an ill-chosen stop area, in which case I entirely agree with you. For instance placing your stop 1 tick below a s/r level is generally asking for it, unless you are positive the gate has already been locked or you are a scalper.
