Test it. Then try to break it. I first built EPSILON as a trading simulator. I have since reworked it into a decision lab focused less on producing an answer than on testing how much that answer deserves to be trusted. EPSILON is a research environment for turning market ideas into explicit, testable claims. It combines simulated market observation, strategy testing, evidence provenance, and structured critique in one repeatable decision cycle: Observe → Frame a hypothesis → Test → Interrogate → Refine → Retest EPSILON is not a trading recommendation engine. Its purpose is to make assumptions visible, preserve failed or negative evidence, and show exactly when a result no longer matches the question being asked.
