TSLA hit the 100 day SVM bottom. Next down would be 600 day at 263.48.
At 284 or below, I am comfortable to enter and open Long position with PT at 300 in the ST.

If go down deeper to hit 600 day low at 263 area, I would double down to make it 273 average price.
With 300 ST target, that is about 10% upside swing before ER.

If the bounce fails, from 283 today, next stop might be 263 and if bounce fails again from 263, close your Long position and move on.

However I think 283 bounce seems more likely....
Even if goes down deeper, I would be comfortable knowing all this.

See below for how to determine if bounced successfully.
