STOP LOSS, TARGET LADDERS, AND THE MINIMUM 1:2.5 PLANNED-R FLOOR
Every card enforces a deterministic trigger price, a hard structural invalidation stop, a two-tier profit ladder (50% T1 / 50% T2), and an absolute mathematical floor of 1:2.5 planned risk-to-reward to Target 1.
Applies to morning card level generation, 9:25 AM ET pre-bell calibration, intraday level calculations, live execution telemetry, and runner scale-out defense.
Deterministic trigger price derivation
The Trigger Price is the exact per-share price at which a setup transitions from passive observation (WATCHING) to active execution (TRIGGERED). The engine derives trigger prices algebraically without subjective discretion:
Set above the established pre-market high or multi-day consolidation barrier, buffered by a minimum Wilder ATR(14) fractional noise threshold to avoid false breakout wicks.
Anchored to the 15-minute Opening Range High (ORB) or volume-confirmed intraday resistance shelf, ensuring current price is within 0.5× ATR of entry to minimize latency slippage.
No trade is triggered on indicator anticipation. The tape must print at or above the exact trigger price during regular trading hours to validate entry. If market price opens above the trigger by more than the allowable gap slippage threshold, the setup is declared INVALIDATED to prevent chasing extended prints.
Structural invalidation stop placement
Every setup card requires an Invalidation Stop before publication. The stop loss defines the precise price level where the thesis is falsified. Risk per share is defined strictly as:
Stop placement adheres to three non-negotiable rules:
- Structural Support Anchor: Stops are anchored to structural technical levels—pre-market consolidation lows, previous session swing support, or the session VWAP defense band—never to arbitrary dollar amounts.
- ATR Noise Clearance: The distance between the trigger and stop must exceed 0.3× Wilder ATR(14). Setting stops inside normal intraday volatility noise creates premature stop-outs and is rejected by the level engine.
- The Non-Widening Rule: Once a card publishes, its invalidation stop can never be widened or lowered. Moving a stop loss further away is classified as an existential risk failure.
If the regular-session tape prints at or below the invalidation stop price, the card immediately transitions to STOPPED. The realized outcome is logged as exactly −1.00R.
Target ladder and two-stage scale-out management
Day Trade Edge setups employ an institutional two-stage scale-out management plan (ScaleOutManagementPlan) designed to capture asymmetric gains while protecting accumulated open profit:
When market price reaches Target 1, exactly 50% of the position is exited (target1ExitFraction = 0.5). This locks in a minimum +1.25R realized gain on the total position (+2.50R × 50%).
The instant Target 1 executes, the stop loss on the remaining 50% runner automatically shifts to the original entry Trigger Price (runnerStopAfterTarget1 = 'BREAKEVEN'). The trade can no longer incur a loss.
The remaining 50% runner continues tracking toward Target 2, capturing trend continuation or volatility expansion up to a hard ceiling of 3.0× ATR above entry.
If the runner reverses and hits the entry price, the trade logs a blended return of +1.25R (BREAKEVEN_STOPPED). If Target 2 is reached, the trade settles at its full blended multiple (50% T1 + 50% T2), maximizing upside while maintaining absolute capital preservation.
The hard 1:2.5 planned-R mathematical floor
The foundation of Day Trade Edge expectancy is the 1:2.5 Planned-R Floor. Planned R multiple is calculated as:
Any setup where planned R is less than 2.5 is rejected automatically at Stage 4 of the qualification funnel. No catalyst strength, executive insider cluster, or volume surge can override this mathematical requirement.
Retail trading systems often accept 1:1 or 1:1.5 reward-to-risk ratios, which require unrealistically high win rates (>60%) to overcome transaction costs and slippage. Requiring minimum 1:2.5 planned R ensures the strategy generates positive expectancy even at modest win rates (35–40%), creating institutional durability over hundreds of trade cycles.
If major overhead resistance (such as a 200-day moving average or multi-month supply zone) sits within 0.5% of Target 1, Target 1 cannot simply be pushed higher past resistance to force a 2.5R calculation. In that scenario, the setup fails the resistance clearance filter and is dropped.
Frozen vs Changeable Trade Levels
| LEVEL FIELD | LOCK TIMING | IMMUTABILITY RULE |
|---|---|---|
| Trigger Price | 09:25 ET (Morning) / Publish (Intraday) | Locks permanently. Never modified post-publication. |
| Invalidation Stop | 09:25 ET (Morning) / Publish (Intraday) | Initial stop never widens. Management moves stop to entry only after T1 fill. |
| Target 1 & Target 2 | 09:25 ET (Morning) / Publish (Intraday) | Target levels freeze permanently to guarantee planned R floor integrity. |
| Planned R Multiple | 09:25 ET (Morning) / Publish (Intraday) | Locked ≥ 2.5R at publication. Recorded in cryptographic payload hash. |
