To be really good you just need to be better than the average trader. And for that you don't need to sell the exact top or buy the exact bottom. It's enough to stagger purchases and sales in proportions that depend on the probabilities of price increases/decreases by certain numbers. Finding the probabilities is the trick here, as well as averaging them out in a way that guarantees you a performance band in which your portfolio will fall with a given probability. Doing that requires an understanding of time series as well as the ability to process large amounts of data (beyond just the price charts) though.
Agreed, but why didn't we see the crash coming? If there was a pattern to predict that, not many here did.
Did you know after it went up towards 20k that within a month or so it would hit 6K? I didn't.
That's exactly what I would like to be able to figure out - partially, tentatively, doubtfully, of course. In another post, kurious said something to the effect "Exactness is not possible, but getting as close to it as we can is a noble art." I'm quoting from memory, words might be off. Well, that's exactly what I hope to do, and I'm asking for help from several points of view. The advanced conspiration theorist, the technical analyst, the macroeconomist, the street-wise long time exchange user. I'm none of that yet, but honing my gut feeling skills seems a worthy endeavour.
