That call was based on both TA and FA:
1. TA: Once the bottom Williams % was hit on the daily chart, it usually bounces up to the SMA line what was around 330. If you check the daily chart the SMA was touched 3 days ago at 327.
2. FA: It is a cult stock so we don't need to expect logical behavior, or should I say the expectation is cultist logic. 300 or just below that has been a floor, and I figured it would hold. People and maybe institutions too rush in to buy at that level...
