have to keep in mind that all such TA is usually based only on the data which is obtained from CMC, which gets it from exchanges (and that also - not from all, but some). however a lot of stuff going in private, aka OTC. that's basically not being reflected in the data from those exchanges - since those are private deals made sort of P2P, directly, not at all on any of those exchanges. thus such TA is not completely accurate since it is dependent on limited data...
