Discussion

The combination of order-entry mechanics and available CBOE options products (only monthlies existed for several of the early years of the backtest duration) caused the strategy to experience:

~42% of time in the market
material amounts of timing luck

As highlighted in the methodology section, the “ultra short” 0 DTE strategy calls for options with 0-3 DTE horizons. 0 DTE would equate to a position opened and expiring same day whereas a 3 DTE position would equate to a position opened on Friday and closed on a Monday (Fri = 0 DTE, Sat = 1, Sun = 2, Mon = 3).

DIS, unlike SPY, does not have Monday-expiring or Wednesday-expiring options. Therefore, positions are opened Tues (3 DTE), Wed (2 DTE), Thurs (1 DTE) and Fri (0 DTE) so long as a delta exists in the respective range.
