I do not have any software for backtesting. Besides, if XLU stayed in range for 2 or 3 months, my P&L chart for long XLU and long leap XLU put is very favorable. I would think that a ratio calendar will work as well, in that case you have to sell 50% or less of the number of your leaps on a monthly basis in case it gaps down in a black swan event.
In case your are interested.
