🔴 Skip the roll — defer the decision

Roll locks capital 133 days at sub-floor (0.56%/wk). That's worse than wheeling the cash elsewhere.

When to roll, when to assign, when to expire

Rolling a cash-secured put feels safe because you avoid the "loss" of assignment. But rolling almost always trades short-term comfort for long-term suboptimal capital allocation. The framework rule on rolling is strict for exactly this reason.

The roll rule

Roll only when ALL of the following are true:

  • The roll is for a credit (you collect more from the new sale than the BTC of the old)
  • The new weekly cash-on-cash ≥ 1.2% on the new capital base
  • You still want the shares at the new strike
  • The new DTE is ≤ 30 days (anything longer = locking capital sub-floor)
  • You are NOT rolling up — only down or sideways

When to let it assign

Letting the put assign is usually correct when:

  • The roll fails the 1.2%/wk floor on the new capital base
  • You have enough cash to cover the assignment without forced liquidation
  • You can write a covered call at cost basis that pays for itself
  • The cash freed by NOT rolling can earn more than the roll would have yielded

When to let it expire

If the put is OTM and BTC cost is below 10% of original premium, let it expire. Don't pay $0.05 to close a contract worth $0.05 — let theta finish the job and avoid the commission.

The roll trap

Rolling out 90+ days at a sub-1% weekly yield is the most common mistake in retail wheel trading. The capital is locked, the time value paid in the roll is wasted, and the trader spends 3 months waiting for an outcome they could have realized today.

The math is simple: if the roll yields 0.5%/week and you could redeploy that capital at 1.5%/week elsewhere, rolling costs you 1% per week × number of weeks locked. Over 12 weeks, that's a 12% opportunity cost on the capital base. Always run the math.

Understanding the Roll Calculator

This calculator evaluates whether rolling a cash-secured put (CSP) or covered call (CC) actually improves your position. It compares the net credit (or debit) of the roll, the new break-even, and the time you're committing — so you can apply the framework's core rule: roll for credit, or don't roll at all.

The Framework Rules

Wheel strategy practitioners follow a small set of triggers when deciding to roll:

  • 21 DTE trigger: Reassess every open position at 21 days to expiration. Gamma risk accelerates sharply inside this window.
  • Roll for credit OR take assignment. A debit roll is just paying to delay the inevitable.
  • Roll out, then out-and-down (puts) or out-and-up (calls). Stay in the same expiration cycle structure; don't jump to LEAPS to "save" a position.
  • Cap the roll at 45 DTE. Going further locks capital and reduces theta efficiency.
  • If no credit is available within these constraints, accept assignment and switch to the other side of the wheel.

The math is simple:

Net credit = Premium of new short - Cost to close current short
Effective new basis (CSP) = New strike - Net credit per share
Effective new basis (CC)  = New strike + Net credit per share

Worked Example

You sold a 30-DTE MSFT $420 put for $5.00. MSFT has dropped to $410 and your short put is now worth $11.00 with 21 DTE remaining. You're down about $600 unrealized on a single contract.

The calculator evaluates rolling to the 35-DTE $415 put trading at $13.50:

  • Cost to close: $11.00 x 100 = $1,100
  • Premium collected on new short: $13.50 x 100 = $1,350
  • Net credit: $1,350 - $1,100 = $250
  • New effective cost basis if assigned: $415 - ($5.00 original + $2.50 net roll credit) = $407.50
  • DTE added: 14 extra days of capital commitment

The roll generates a real credit, lowers the effective basis below the current $410 print, and stays inside the 45 DTE cap. That passes the framework filter.

Now consider the alternative: rolling to the 35-DTE $420 put trading at $9.50.

  • Cost to close: $1,100
  • New premium: $950
  • Net: negative $150 (debit roll)

The framework rule fires immediately: do not pay to roll. Take assignment at $420, then start selling covered calls against the shares.

Common Mistakes

  1. Rolling deep ITM positions for tiny credits. A $0.05 credit on a $50 ITM put is just kicking the can; gamma will overwhelm theta.
  2. Rolling past 45 DTE. Eventually you're holding a stale position for negligible weekly yield.
  3. Rolling down-and-out so far that the new strike is unrealistic. If the new strike is below where you'd actually want to own the stock, just accept assignment now.
  4. Ignoring the assignment alternative. Assignment is a feature of the wheel, not a failure mode. CCs sold above cost basis are how you exit profitably.
  5. Rolling at 30+ DTE out of fear. The 21 DTE trigger exists because gamma is mild before that. Earlier rolls give back theta you've already earned.

Bottom Line

Reassess at 21 DTE. Roll only when the math produces a net credit, the new expiration stays inside 45 DTE, and the new strike is one you'd be comfortable getting assigned at. Otherwise, take the assignment and flip to the covered-call side of the wheel. Debit rolls are how small losses become permanent ones.
