Bitcoin- New leg down to 40k zone

After the weekend's strong sell of, Bitcoin has started to rebound, as it was normal, and has reached my sell zone above 50k.
The structure of this rebound is clearly corrective in nature and seems to be over.
I expect a new wave of sales for bitcoin and my target for this short trade is 40.
Confirmation that the correction is over, comes with a daily close under 50k
