 Investing-signal platform for US equities. It runs one strategy, and it is a boring one:

After an initial-stop exit, re-enter only after the gate has failed and subsequently qualified again.
 
 **Philosophy:** don't predict price — rank it. The edge is *relative* strength across the universe, and the discipline is in the exit: cut losers fast, let winners run until the trail catches them.
 
 **What is NOT the edge — read this before trusting a number on screen.** The composite score, the 5 dimensions, sentiment, fundamentals, and Structural S/R are **display context**, not validated predictors. The Gate Target Ladder is screening machinery that preserves the production setup population; it is not a claim about true market structure. In particular:
 
-- **The headline "target" is not an exit.** It comes from the internal **Gate Target Ladder** and exists only to compute the R:R and reach-probability used by the activation gate. Human-facing chart S/R is a separate model. The live exit reads neither. Across 320 backtested production trades the exit reasons were **144 initial stop, 98 trailing stop, 78 max hold — and 0 targets.** Honoring the target as a take-profit was tested and *halves CAGR* ([research](docs/research/sr-levels-and-exits.md)).

-**How to read the exit box.** The initial stop is tight (1.5× ATR) and the trail is wide (3× ATR), so the trail sits *below* the initial stop at entry and only takes over once price has advanced roughly 1R. Cut fast when wrong; give room once right. That asymmetry is what produces the right-tailed return profile the strategy depends on — most trades lose a little (win rate ~37.5%), a few win big (best trade +12.9R), and *that is why there is no take-profit*.

+**What happens after an initial stop.** The stop always closes the trade and realizes its costs. The ticker is then locked until a successful daily full-universe scan first observes it outside the production gate and a later scan observes a fresh qualification. A continuously qualified ticker therefore cannot generate an immediate duplicate entry. Other exit reasons do not start this reset. See the [daily post-stop re-entry study](docs/research/post-stop-reentry.md).

+The production policy is **normal gate reset**, evaluated with daily setup opportunities and live-like full-universe ranking. An initial stop always closes. Re-entry unlocks only after a later successful daily scan observes the ticker failing the gate and a subsequent scan observes it qualifying again. The study replayed 1,011,248 point-in-time candidate observations across 505 tickers from 2022-06-24 through 2026-07-02, with the production GTL gate, 80/20 rank, exit, fees, sizing, and 10-position capacity.

Its lead over both survived costs of 0.2% and 0.3% per side. The result is capacity-specific: cooldown 5 won at capacity 5, while immediate had slightly higher return and Sharpe at capacity 15. Production uses capacity 10, so that is the portfolio for which this decision is valid.

+`gate_reset` and a simple `next_session` block happened to produce the same executed live-universe portfolio in this sample. Their rules are still different: this establishes that same-day re-entry was harmful here, but does not isolate a separate historical return premium from the reset condition. Gate reset was promoted because it represents a genuinely new signal episode and did not sacrifice results in the production book.

+# Post-stop re-entry: daily policy study and production decision
+
+## Decision
+
+Use a **normal gate reset** after an initial-stop exit:
+
+1. The initial stop always closes the trade. It is never cancelled because the
+   ticker still passes the gate.
+2. Re-entry remains locked until a later full-universe daily scan observes the
+   ticker **failing** the production activation gate.
+3. The lock remains in place until a subsequent daily scan observes a **fresh
+   qualification**.
+4. Only then may the ticker return to the actionable setup list or be opened
+   through `create_trade`.
+
+Trailing-stop, time, target, and manual exits do not start this state machine.
+Scanner errors do not count as a gate failure. The two transitions are persisted
+on the latest initial-stop `PaperTrade`, so neither a service call nor a restart
+can bypass the rule.
+
+This replaces the previously proposed fixed five-session lockdown. The normal
+reset counts an unqualified stop-day close when that close is observed after the
+stop. The stricter experiment, which required a failed close on a later session,
+was not promoted.

+| `gate_reset_improved` | Gate reset plus a higher new stop and non-weaker production rank |
+| `two_session_confirmation` | Require two consecutive qualified post-stop closes |

+At the production capacity, normal gate reset improved all four portfolio
+objectives relative to immediate re-entry: higher total return, CAGR, and

+The gate-reset result did not depend solely on the earlier training period: it

+
+## Cost and capacity sensitivity
+
+At the production capacity of 10, gate reset remained ahead of both immediate
+and cooldown 5 as costs increased.
+
+| Cost per side | Policy | Total return | CAGR | Max DD | Sharpe |
+|---:|---|---:|---:|---:|---:|
+| 0.1% | Immediate | 348.4% | 45.2% | 24.3% | 1.67 |
+| 0.1% | **Gate reset** | **388.1%** | **48.3%** | **21.6%** | **1.77** |
+| 0.1% | Cooldown 5 | 250.8% | 36.6% | 22.2% | 1.47 |
+| 0.2% | Immediate | 296.3% | 40.8% | 25.2% | 1.54 |
+| 0.2% | **Gate reset** | **333.0%** | **44.0%** | **22.9%** | **1.64** |
+| 0.2% | Cooldown 5 | 209.9% | 32.5% | 23.4% | 1.33 |
+| 0.3% | Immediate | 249.8% | 36.5% | 26.0% | 1.41 |
+| 0.3% | **Gate reset** | **284.0%** | **39.7%** | **24.2%** | **1.51** |
+| 0.3% | Cooldown 5 | 164.0% | 27.3% | 24.7% | 1.16 |
+
+The capacity sweep is a real limitation, not a footnote:
+
+| Capacity at 0.1% cost | Immediate Sharpe / CAGR / DD | Gate-reset Sharpe / CAGR / DD | Cooldown-5 Sharpe / CAGR / DD |
+|---:|---|---|---|
+| 5 | 1.33 / 31.9% / 16.8% | 1.37 / 32.8% / 17.5% | **1.46 / 35.8% / 18.3%** |
+| **10 (production)** | 1.67 / 45.2% / 24.3% | **1.77 / 48.3% / 21.6%** | 1.47 / 36.6% / 22.2% |
+| 15 | **1.66 / 44.8% / 24.3%** | 1.63 / 43.0% / **21.6%** | 1.33 / 32.8% / 22.2% |
+
+The promotion is therefore specific to the actual 10-position production book.
+At capacity 5, cooldown 5 ranked best; at capacity 15, immediate had slightly
+higher return and Sharpe while gate reset retained the shallower drawdown. Do
+not generalize the chosen rule to a differently sized portfolio without rerunning
+the matrix.
+
+## Legacy-rank sensitivity
+
+The older candidate-only ranking approximation also favored normal gate reset
+over immediate and cooldown 5, although `next_session` was slightly stronger.
+

+|---|---:|---:|---:|---:|---:|
+| Immediate | 357.4% | 45.9% | 17.9% | 1.73 | 480 |
+| Next session | **421.5%** | **50.8%** | 18.5% | **1.86** | 466 |
+| **Gate reset** | 408.3% | 49.8% | 18.3% | 1.84 | 464 |

+## Why gate reset was promoted
+
+- It is tied to a new signal episode instead of an arbitrary elapsed time.
+- At the production capacity, it beat immediate and five-session cooldown on
+  return, CAGR, drawdown, and Sharpe.
+- The advantage survived costs of 0.2% and 0.3% per side and the disjoint 2025+
+  test book.
+- It avoids cancelling a valid stop: the loss and transaction costs are always
+  realized before any later trade.
+- It avoids the extra filters that weakened strict reset, improved-setup reset,
+  and two-close confirmation.
+
+The correct interpretation is deliberately modest: **normal gate reset is the
+best production rule among the tested policies for the current 10-position
+book.** It is not proof that gate reset is a universal source of alpha. Forward
+paper-trade monitoring is still the only genuinely new evidence.
