AI Market Maker v6.1.3

Release Date: July 29, 2026 Tags: CLEANUP, NO-BEHAVIOUR-CHANGE Superseded by: v6.1.4 — see the correction block below before relying on this page.

Overview

Version 6.1.3 removes the legacy bot subsystem that the v6.1.2 price-engine rewrite superseded. Nothing outside it used any of it, and no shipped behaviour changes.

---

Upgrade Notes

No migration, no configuration change, no behaviour change. Existing bots, markets and statistics are unaffected — they were already served by the live engine. Requires a backend rebuild.

Changed

Removed

The legacy bot subsystem is removed in full: its manager, coordinator, factory and base class, the behaviour generators, and the five personality classes.

Bot personalities are a live, documented feature — they are simply implemented elsewhere. The supported path is database-backed, with per-bot creation, editing, statistics and lifecycle driven by the admin Bot Management screen. Every capability in the removed code already exists there:

• personality-driven side selection (accumulator/scalper/market-maker take the buy leg; distributor/swing take the sell leg)
• per-bot daily trade caps, with a scheduled job that resets the counters
• configuration-driven order sizing and human-like size variance
• volatility-aware dynamic spread — strictly better than the removed fixed 15 bps
• per-bot pause/resume, and richer aggregate statistics

Corrections applied in v6.1.4. Two claims above did not survive review:

• "Every capability in the removed subtree already exists there" was not true of trade CADENCE or order-SIZE SHAPING. The live engine had neither: cadence was a single constant coin flip per tick with no intraday variation, and sizing was a uniform band of ±20% around the configured average. Those two capabilities were genuinely lost and have been rebuilt in v6.1.4.
• "The removed bot configuration was a field-for-field duplicate" was false. The two shapes were different — the removed one carried a field the live one does not, and lacked the status, last-trade and daily-count fields the live one keeps — and the name collision was a hazard.

The claim that the removed code was unreachable, and that re-introducing order-flow-driven PRICING would re-open the exploitability the rewrite closed, both stand — and v6.1.4 is built specifically to honour the second.

The one thing the old subsystem did differently was order-flow-first price formation, where price emerged from bot orders and each personality applied a directional bias. That is not a missing capability — it is precisely the model v6.1.2 replaced. The current engine is price-first: the price process advances each tick and trades are printed to follow it. Re-introducing order-flow-driven pricing would re-open the exploitability the rewrite closed, so this code was not a candidate for wiring.

The sibling documentation page for bots documents the five personalities as the live feature, and is deliberately unchanged — removing the legacy subsystem changes no documented behaviour.
