All my own work,
as the rejected entry "Commies don't stick soda" patently makes clear. Never met Occam, but I understand he makes damned fine razors....
Back to the actual discussion, cynic that I am I can't help feeling that Prechter made more selling the tapes than anyone did watching them - the exchange rate will have to drop substantially before 900 anything looks a bargain, including the Zloty.
Ultimately you can synthesize any complex waveform by superposing component waves - that's pretty well how your PC delivers music - so the ability to decompile complex structure into its components isn't actually magic, it's just data crunching. The problem is that taken over the period 2000-2005 (for example) if you had all the data you could decrunch it, and find the combination of waves that fitted the actual share price chart, that is not necessarily the same set of waves that will make the 2000-2004 chart look correct.
It all fits really well provided you don't assess how it fits beyond today - the further forward you take today's analysis the further reality will diverge from the plan of what ought to happen.
Human nature then takes one of two courses, either the software vendor is called all the names under the sun in the brief period before the overdraft causes broadband services to terminate, or the buyer decides they 'didn't follow the plan properly' and blames themselves for lack of commitment (even though a complete fanatic would have given it up as a lost cause by that point) or failure to analyse correctly... this is no great revelation, but seems to take some an age to understand - a decent system should be simple and robust enough to make misinterpretation the exception, not a common occurrence. If signals are regularly misinterpreted then the fault is in the system, not the user. The basic idea behind a system is to make it pretty well automatic, to remove human influence to a large degree so that fads and fancies don't mess up the steady move towards zillionairedom, a system that requires too much interpretation will bomb the moment a few losses sow the seeds of doubt.
Flip a coin, over the long term it'll be 50% right - that's not bad compared to many systems I've tested over the past 2-3 years!
