策略定位

stage:P3 | status:bench

策略类型(mother theme):均值回复

角色(role):challenger

挑战基线(challenge baseline):均值回复主baseline(pairs/fair-value)

唯一增量(unique increment):cbETH-ETH rolling fair-basis MR

下一步唯一动作(next action):先解除交易接入阻塞(Coinbase),否则维持 shelve

研究结果与原理(人话版)

核心思想:价格偏离某个“相对公平值”后,倾向于回归;常见风险是趋势单边把回归交易持续压制。

当前 rank 要回答的核心问题:这条“独立增量”到底是在补 baseline 的哪个短板(入场、过滤、仓位、退出、执行)?

拆分视角

内容说明
baseline均值回复主baseline(pairs/fair-value)研究母体(被挑战或被增强对象)
rank incrementcbETH-ETH rolling fair-basis MR该 rank 相比 baseline 的独立增量
role: challenger挑战/替代 baseline 的候选路线,先追求可解释增量,再看成本后存活。该 rank 在 P2/P3 体系中的职责边界

信号定义(落地模板)

  • Universe:围绕该 rank 对应的可交易标的集合;优先采用当前在 artifacts/runner 中可复现的标的与时间框架。
  • Baseline 主信号:均值回复主baseline(pairs/fair-value)(若该 rank 不是 baseline,本项为“被挑战或被增强的母体”)。
  • Rank 独立增量:cbETH-ETH rolling fair-basis MR,要求在报告中单独说明它改变了 entry / filter / sizing / exit 的哪一段。
  • 策略类型:均值回复,建议按“信号本体 vs 过滤层 vs 执行层”三段写清。
  • 角色归属:challenger,需要明确它是否应独立承担 alpha 归因。
  • 执行信号定义:区分“候选触发点”与“最终执行信号”。候选触发点通过后,仍需经过 veto/filter/执行约束才允许下单。
  • 退出与风险:最少写明超时退出、反向信号退出、极端风险保护三类规则。
  • 成本口径:明确默认费率 + 滑点假设,并写出“成本提高后是否仍存活”的结论。

# Rank 183 deep-dive proxy scan (2026-04-01)

## Goal
Answer three concrete user questions:
1. Why does Rank 183 use `CBETH spot + ETH perp` instead of two generic coins on the same exchange?
2. How stable is Rank 183 historically, month by month?
3. If we switch to generic crypto pairs like `BTC/ETH`, `ETH/SOL`, `ETH/XRP`, `SOL/XRP`, can simple correlation be turned into a tradable mean-reversion strategy?

## Key conclusion
- `Rank 183` is a **basis mean-reversion** strategy, not a generic cross-asset pair trade.
- The reason it uses `CBETH spot + ETH perp` is that there is a clearer economic anchor:
  - `CBETH` is a staked-ETH spot asset with a premium/discount structure,
  - `ETH perp` is the cheap hedge leg for broad ETH beta,
  - so the trade is betting on **basis / fair-value convergence**, not just "these two charts usually move together".
- By contrast, `BTC/ETH`, `ETH/SOL`, `ETH/XRP`, `SOL/XRP` are mostly **cross-asset correlation pairs**. They may co-move, but they do not automatically have a stable fair-value anchor strong enough for post-cost mean reversion.

## Rank 183 local honest sample
Using the current artifact:
- `reports/artifacts/quant_digests/cbeth_eth_basis_probe_20260326_0850_15m/trade_log.csv`

The local trade log only spans:
- start: `2026-02-01 18:45 UTC`
- end: `2026-03-26 08:45 UTC`

So the exact current paper-spec evidence is only about **2 months**, not 1 year / 3 years / 5 years.
Also, an exact `5y` backtest on the same instrument is not literally possible because `CBETH` itself is younger than 5 years.
