Are those movements (see arrows) only random or are they the consequence of the trading of hedgefunds?
A lot of reasons can be found: algorithms, stop-loss, sentiment of traders with weak hands (cyclical traders)
Interestingly it hasn´t been only the up - and down movement of BTC but also the traded volume. This is the reason why I think that big hedgefunds are at least to a big part responsible for this phenomenon.
If this is the case alle technical analysis should be taken very careful; cause the hedgefundmanagers know more than us the function. They can take in mind the reaction of the market, give a little impulse and wait.
So they can make profit in both directions.
This isn´t illegal but we - the smaller traders - should never forget that " big brother " (hedgefunds) is watching you.
