Everything is indicated in the chart. Basically, BTC moves in a range. It does sometimes distortions which is wrapped by yellow boxes. Along the range, BTC has decreased its volume output, which means the weakness. Hence, IF BTC wants to go up, it would need to accumulate some volume. That means, in my opinion, that it has to provide buyers some opportunity around the closest demand area.
