A roll is a new trade
Rule
Evaluate any roll through the identical entry gate you would apply to a fresh position: current implied-vs-realised, current liquidity, post-trade portfolio greeks.
What it means
If it would not pass as a new trade, close instead. Published rolling rules ('roll at 14-21 DTE if challenged', 'never roll for a debit') have no backtests behind them, but this reframing is logically forced and removes the loss-aversion failure mode without needing to believe any of them.
