Broker-Agnostic Position Reconciliation
A SaaS sidecar that continuously reconciles strategy-level positions, net portfolio exposure, persisted state, and broker-reported positions. It would help independent traders catch mismatches before they become expensive live-trading incidents, especially after restarts or partial outages.
これが重要な理由
When you run multiple strategies on the same instrument, the hard part is no longer signal generation. The real stress starts when one strategy thinks it owns a position, your broker shows a different net exposure, and a restart leaves you guessing which state is correct. You end up stitching together memory state, local files, and broker responses while hoping one process does not interfere with another. The cost is not just time. A small mismatch can trigger unintended orders, broken risk limits, or silent drift that only becomes visible after real losses. You want a system that tells you exactly where state diverged and how to recover safely.

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Position attribution may be impossible to infer reliably for some broker setups without deeper integration than users are willing to grant
- 2The product may be seen as too risky unless it proves accuracy over many edge cases
- 3The reachable paying segment may be narrower than expected because simpler traders do not hit this pain yet
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
This was the strongest and most specific pain in the discussion, with repeated references to multi-strategy state drift, restart recovery, and keeping internal and broker positions aligned. The comments describe this as the hardest engineering problem rather than a minor annoyance, and several users already maintain custom reconciliation layers, which is a strong signal of unmet need.
