IMHO:
This is a grey area, where experience and screen time would count.
For example, if there is a three-push reversal pattern confirmed by price-momentum and price-volume double divergence on the five-minute chart of ES, under normal circumstances I would look for reversal signal immediately, since ES is a mean-reverting market. The basic assumption is that I trust the momentum indicator producing the divergence signal. What would a trader do, if
a) the volume divergence is missing ?
b) the above divergence pattern occurs on the five-minute chart of gold futures (GC), a running market ?
c) The above divergence pattern occurs five minutes before the announcement of the Fed Fund Rate or release of the monthly job report ?
I guess it all depends on the personality of the trading instrument, time of the day, confluence with other indicators, confluence with psychological levels, support or resistance, time-frame of the divergence signals, etc.
