- month's H/L/C levels on D time frame (drawn as circles)
- week's levels on 4h (as crosses)
- day's levels on 1h (as line)
These levels act as over and over again, see current (08/24/2020) BTCUSD chart, the previous month's close (blue circles) did act as support and held on 08/11, also prev month's high (red circles) was not broken on 08/21. Once these levels break we might see lower prices but so far both of them act as good support to consider.
