In other words does it have an expiry date?
My view and experience is that most types of analysis in terms of anticipation of future price action--- favorable to the analysis is valid for 2 to 6 periods again regardless of time frame---be that 5 min to weekly.
I feel an experienced practitioner can be better than 50% correct/accurate in analysis in the first 6 periods and less so there after-- to having no effect on current trading within 20 periods in that timeframe.
Of course analysis can alter the very next period and it is one of the characteristics of a good practitioner to recognise when analysis is no longer valid/or under threat.
Analysis can also further support previous analysis within the next 6 periods so experience should also give the analyst the ability to confirm his analysis going forward as well.
Some analysis can remain valid permanently going forward such as Elliott.Support and Resistance.
There are many here who (Like me) enjoy posting our analysis up for all to consider. It maybe an interesting exercise to see just how long our analysis does hold up---and how often---IE what %.
