By name: 0dte-flow description: >- 0DTE day-trading playbook for a small account — Ghost Alpha signals into Tradier XSP (Mini-SPX) same-day options with strict IFTTT entry/exit rules and hard risk guardrails. Use when Michael wants to run a 0DTE session, size a contract, decide whether a signal qualifies, or apply the exit cascade. This is a DECISION-SUPPORT playbook — it drafts the plan; Michael places every order.
0DTE Day-Trading Flow
Ghost Alpha A+/A signals → Tradier XSP 0DTE options → same-day close.
Why XSP
XSP (Mini-SPX) is 1/10th of SPX, cash-settled / European (no assignment risk), with 0DTE M/W/F on Tradier. Cheap enough for a small account. Fallback: if XSP isn't tradeable, use SPY 5+ OTM ($0.10–$0.30).
Position sizing (example: $75 account)
| Rule | Value |
|---|---|
| Max per trade | $30 |
| Buffer | $10 |
| Trades per day | 2 sequential (never concurrent) |
| Strike | 2–3 OTM ($0.15–$0.50/contract) |
| Max daily loss | $60 (2 full losers = walk away) |
Entry — ALL must hold
Ghost Alpha Grade ≥ B on SPY 5min
AND signal = mega_bull OR mega_bear
AND RVOL > 1.2
AND time 9:30–11:30 AM ET
AND trend_age < 15 bars
AND no open 0DTE position
Exit cascade — first match wins
| # | Type | IF | THEN |
|---|---|---|---|
| S1 | 🔴 Hard stop | Loss ≥ -50% | SELL (non-negotiable) |
| S2 | 🔴 Grade death | Grade → D/F | SELL (thesis dead) |
| S3 | 🔴 Reversal | Signal flips bull↔bear | SELL (wrong side) |
| T1 | ⏰ EOD | Time ≥ 2:30 PM ET | SELL (theta cliff) |
| P1 | 🟢 Double | Gain ≥ +100% | SELL (take the W) |
| P2 | 🟢 Fading | Gain ≥ +30% AND Grade → C | SELL (lock it) |
| P3 | 🟢 Afternoon | Gain ≥ +50% AND time > 1 PM | SELL (theta) |
| T2 | ⏰ Dead money | Time ≥ 12 PM AND ±10% | SELL (free up trade 2) |
Re-entry: Trade 2 only if Trade 1 closed, buying power ≥ $20, and a new A+/A signal fires. Two losers → DONE for the day.

"0DTE options are like Mike Tyson — rich in 5 minutes or knocked out in 3. The difference is whether you have a plan when you walk in the ring." — Sam 👻
