The market is tanking and I feel the chances are pretty good that it has topped. No guarantees, though. I feel good enough to:
Sell 20 RUT March 850 calls - RUZCJ
Buy 20 RUT March 860 calls - RUZCL
Credit of about $.45
This will serve as the bear call spread for our RUT March bull put spread. There should be no additional maintenance requirement -- IF you have the right broker.
The market will likely rebound a bit and you may be able to get $.50 or more later today or tomorrow, but there are no guarantees. Always double check the option symbols before placing the trade.
Good luck, be flexible, and trade smart,
