There are T/A tools that measure noting but investor sentiment, such as OBV, DMI, and RSI readings. The best way to "know" what people/sheeple/skeeerdy cats will do next is to look at exactly what they are thinking at any given time. I don't use volume statistics or moving averages at all in my chart analysis because they are worthless indicators imo. Price is the most important, and "knowing" which price highs/lows need to be breached is the "bible" of being a successful trader. If you asked the ave technical analyst where the closest major support area is on the stock they were trading, 90% of them would have no idea. :-) But yes, there are guarantees. For bitcoin, the technicals on bitcoin tracker GBTC already told you that yesterday's 297 low will get taken out. And "actual" bitcoin will follow the path of GBTC (not the other way around), therefore, bitcoin is "guaranteed" to breach yesterday's $2134 low. Let's watch and see if it happens over the weekend.

You can pull this live bitcoin ticker chart back to the 3 day window if it goes to the one hour default. That will show you the low that is definitely going to be taken out in short order.
