Copy Trading v6.1.2

Release Date: June 30, 2026 Tags: MONEY-SAFETY, COPY-TRADING, FUND-FLOW, RECONCILIATION, IDEMPOTENCY

Overview

Version 6.1.2 is the copy-trading half of the platform-wide Core v6.4.9 money-safety audit. It fixes a set of follower fund-flow bugs that could strand or leak funds across the place → hold → fill → cancel lifecycle, makes the allocation idempotency keys retry-safe, and adds a reconciliation job that cleans up follower trades whose underlying order was cancelled or closed out of band.

Requires Core v6.4.9 and the Ecosystem extension (for live order routing).

Added

Reconciliation

• Added a reconciliation job that tears down follower copy-trades whose underlying ecosystem order was cancelled or closed out of band, releasing any funds left held in the follower's copy-trading wallet.

Fixed

Follower fund flow

The copy-trading follower lifecycle leaked and stranded funds at several points; the full place → hold → fill → cancel flow on the follower's copy-trading wallet is now correct and reconciled. Each follower mirror order is tracked by its own ecosystem order id (previously only the leader's id was stored, so cancels and fills could never locate the follower's order). Every teardown path — a leader cancelling, a follower stopping a subscription, or removing allocated funds — now releases the follower's held balance and frees the matching allocation by the actual unfilled amount, so a partially-filled order releases exactly its remaining portion rather than the whole cost. The mirror order's cost is held fee-exclusive to match the engine's hold/refund math, follower fills now sync the trade's status and accumulate executed amount and fee across partial fills, and a mirror order whose database reservation rolls back is compensated (the orphaned ecosystem order is rolled back) instead of resting unfunded and re-loading on restart. Withdraw and stop paths guard against moving funds locked in open orders.

Idempotency and stability

Copy-trading allocation / add-funds keys are now deterministic and retry-safe, and the copy-trading emergency-stop returns a clear 503 (instead of a generic crash) when the ecosystem extension is absent.
