NDX - Downward channel setup

Hi guys, we've had a great run upwards since the double bottom at approximately ~10700 levels.
I've drawn some new lines that could show us the way forward. However, this idea is going downwards.

If the fiscal stimulus goes through congress and gets accepted, i believe this channel will be invalid.
However, if it fails the coming week, we will be ready for a new selloff.

Good luck with the trading the coming weeks!
