The trailing threshold continually moves up from the highest point of open equity, realised or not. Violate it once, and your account is liquidated.
Core idea: What matters at every tick is realised P/L plus any open losses. Convert winners to cash quickly and keep the open risk small enough that the running balance never drops below the floor.

Why Big In-Trade Swings Hurt
The drawdown is recalculated at every intrabar high, so a deep pullback after a large unrealised gain can shrink the remaining buffer dramatically. Sizing and stop-placement must anticipate worst-case open loss, not just closing balance.
1 – Risk Budget & Position Sizing
| Setting | Typical 50 K Eval Value | Reason |
|---|---|---|
| Risk per trade | 0.5 %–1 % ($250–500) | Ten full stop-outs before hitting TDD |
| Contracts | 1 mini or 2–3 micros | Shallow open loss |
| Concurrent positions | One strategy at a time | Avoid stacked exposure |
2 – Daily Guard-Rails
- Daily loss cap: ≤ 3 % of account (
>$1 500) — auto-flatten and disable trading. - Daily profit lock: 1–3 % — bank winnings before lunchtime chop.
- Trade count limit: e.g. 4 ops (session breakout) or 20 ops (scalper) — cuts revenge trading.
- Time windows: 09:30–11:15 ET and 14:00–15:45 ET — skip midday doldrums.
- Market-state filter: trade only if
>SVI > 50 %&>|TSI| > 200.
3 – Entry & Exit Engineering (Fib Grid / AFT)
| Tool | How to Apply | Benefit |
|---|---|---|
| Tighter initial stop | 1 × FibGrid 10–20 % | Low $-risk per trade |
| Fast trailing stop | USAR / PSAR or dip below +10 % | Convert float to cash |
| Partial scale-out | 50 % off at +F25 %, runner trails | Lifts TDD floor |
| Smaller targets | First TP at 1 R (≈ +F10 %) | High-frequency singles |
4 – Capital-Preservation Checklist
- Begin each session noting balance, threshold, and buffer.
- Skip trades whose stop > 20 % of live buffer.
- When realised P/L hits 75 % of the initial cushion, consider edging size upward.
- After one full stop or three scratches, drop to micros until you rebuild.
- End-of-day: export fills, grab screenshots, review drawdown logic.
5 – Automating It in AFT / NinjaTrader
- Sizing formula:
>floor(buffer / (stop × tickValue)) - ATM: fixed stop, auto-BE @ +6 t, trail every +4 t.
- AFT presets: start with tighter “B” or “C” turnkey configs.
- Account loss limit: enable NT8 guard to auto-flatten.
- State filter: load strategy only when bias criteria fire.
AFT Workspace Tweaks for Prop Rules
Turnkey workspaces ship neutral; dial them in for prop trading by:
- Accelerating trail stops (FibGrid / USAR / PSAR).
- Auto break-even: risk to 50 % at
first target. - Closer profit targets:
>+10 %,>+25 %,>+50 %. - Running two lots instead of three.
- One-click partials: exit-one, trail-one.
- Trade-plan goals (TPG): caps on trade count, lot count, daily P/L.
Final Take-Away
- Small initial size + rapid profit capture keeps the trailing threshold safe.
- Session-level caps act as emotionless circuit breakers.
- Rule-driven entries (Fib Grid) and exits enforce consistency.
- Automation guarantees you never rely on hope.
