We'll see who responds to my challenge. The questions to be answered... (1) "Is volume helpful in improving overall trading results.. i.e. making more good trades and avoiding some losers, (2) is volume consideration non-conclusive/ineffective and a waste of time, and (3) does volume consideration actually hinder success by resulting in more missed profitable trades"?
As the years gone by me, my attitude changes as well. I now see how just about anything in trading to be an added filter to reduce the number of trades. I think many "NEED" an excuse to take less trades, let's face it, most traders over trade either cause of emotions or too many signals to pull the trigger. So by adding volume, we can form rules to take less trades.
You are right IMHO, volume goes up /down as price goes up/down, does it mean anything which is similar to flipping to get a head/tail. I find it difficult to see a huge bar knowing there can be hardly any volume in it or can be very heavy volume in it. as for myself, I will use volume to exactly reduce trades waiting for divergences of price going higher on less volume, I view volume as "interest" or people's desires to be involved to make a difference, only use it for entries in scalping, day trading or very long term commodity trading, but exits I don't use as my level of patience of being in anything that has much of a retracement-I have already exited.
But I digress.
