Lesson Learned #112: Pre-Market Position Protection Gap
Date: January 7, 2026
Severity: CRITICAL
Category: Risk Management, Phil Town Rule #1
What Happened
CEO review revealed 5 open positions with $1,187.60 in unrealized gains had ZERO PROTECTION:
| Position | Unrealized P/L | Stop-Loss |
|---|---|---|
| SPY | +$74.60 | NONE |
| INTC260109P00035000 | +$151.00 | NONE |
| SOFI260123P00024000 | +$56.00 | NONE |
| AMD260116P00200000 | +$457.00 | NONE |
| SPY260123P00660000 | +$449.00 | NONE |
Root Cause
The daily-trading.yml workflow only set trailing stops AFTER trading activity.
On days with no new trades, existing positions remained unprotected.
Evidence
$ python3 -c "import json; print(json.load(open('data/system_state.json')).get('trailing_stops', 'NOT CONFIGURED'))"
NOT CONFIGURED
Fix Applied
Added protect-existing-positions job to daily-trading.yml that runs:
BEFORE any new trades (needs: [validate-and-test])- At start of each trading day
- Sets trailing stops on ALL existing positions
Configuration:
- Equities: 10% trailing stop
- Options: 20% trailing stop (more volatile)
Prevention
- Session Start Checklist now includes position protection check
- Workflow runs protection BEFORE trading, not just after
- Added deferred item for manual trigger if needed
Phil Town Rule #1
"Rule #1: Don't Lose Money. Rule #2: Don't Forget Rule #1."
A trade without a stop-loss is a hope, not a strategy.
