This is a very simple analysis as it isn't a complicated setup.
Tesla is approaching the 200 day moving average (blue). In the past, this moving average has held up the stock every time although it has fallen through it slightly a few times.
The location of the 200 day moving average also lines up with the bottom trend line of a descending channel. I would suggest measuring the % amounts Tesla has dropped below the 200 day moving average and set your stops accordingly.
