I was able to sell the Mar15 '19 90/130 put ratio for $1.00/contract.
My breakeven is around $49 (Current price is $321.83).
The initial capital requirement here is $1200, so this would be around a 8.3% if margin stays about the same here. Worst case scenario, I'm a baghodler of TSLA shares at $49.
Markets are not efficient.
