Aletheia — End of v2, Start of v3 – Trading Systems – 21 October 2025

Aletheia is not “just another EA.” It’s an agent + MT5 EA that turns real-world events into evidence-backed, broker-agnostic trade setups with a transparent audit trail for every idea.


TL;DR

  • v2 ended due to a broker-side demo account closure (the system relied on that broker’s symbol naming/candlestick data). We reset and are launching v3 on a fresh account.
  • What v2 proved: the agent can link events → market reaction (e.g., ORSTED.DK short) but still let some weak theses through.
  • What’s new in v3: fine-tuned Trade Filter Agent, clean database, and all recent execution upgrades carried forward.

Why v2 ended

The broker closed the demo account we used for v2. Because our live pipeline depended on that account’s symbol mapping and candlestick feed, continuing was not viable. Rather than patch around it, we chose to reset cleanly and start fresh with v3.


What we learned from v2

  • Real signal exists: the agent built solid reasoning chains and connected events to price action (notably the ORSTED.DK short ahead of a ~50% after-hours move).
  • Coverage is high: multiple instruments/events can be analyzed in parallel, great for discovery.
  • But filtering matters: some weak/indirect narratives still made it into positions, producing quick losses. v3 focuses on stronger filtering so only meaningful, well-supported ideas pass.

What’s new in v3

1) Fine-tuned Trade Filter Agent

  • Model: a 1.5B-parameter LLM, fine-tuned on our own reasoning chains.
  • Goal: reject weak logic more aggressively while preserving solid theses.
  • Unseen-data test (balanced set ~120 good / ~120 bad): overall ~68% accuracy; filtered out ~80 bad signals (kept ~40) and kept ~80 good (filtered ~40). The emphasis is on removing bad first. This will keep improving as we accumulate new data for continued fine-tuning.

2) Clean slate & operational reset

  • Fresh database and fresh demo account for v3.
  • All previously shipped execution upgrades carry forward.

3) Carried-forward improvements (from late v2)

  • Trailing Stop-Loss (EA): live and configurable.
  • Adaptive Targets by news latency: TP1/TP2 scale to short/medium/long horizons.
  • Partial closures 50% / 50%: 50% at TP1, remainder at TP2.
  • Upgraded Event Brancher: higher-end model for clearer theses, fewer hallucinations.
  • Execution reliability: lot-step–aware order splitting; robust partials.

Why Aletheia is different

Aletheia starts from reality—news, filings, policy, macro—and reasons forward via:

Event → Branches (theses) → Evidence Check → Position (bias) → Entry timing → Setup → EA execution.

Every setup has a Catalyst and a reasoning trail you can audit end-to-end in the web app.
