At key support, could fall on market weakness

With more selling likely ahead I'll be looking to SPOT as a short. Its currently sitting at a key fib and today's push was unsustained as shown. In a previous session price dipped down quickly to tap the lower fib, I'd anticipate similar action if it falls alongside the market.

Trade closed manually:

Nice drop but not to the fib. As of 9/25 based above fib may see a leg up.
