GPT-6 Astra flipped $240 → $2,860 across 4 live sessions with a built-in safety net: 75% of every win gets auto-locked into reserve (agents can see it but can't touch it).

How it works:
→ Finds trades, verifies contracts, logs P&L, tracks capital—fully autonomous
→ Every green session = 75% of net gains moved to reserve
→ Two red sessions hit → working capital dropped from $895 to $731.40
→ Reserve stayed locked at $1,965 the entire time

Basically: the system protects profits from itself. When it bleeds, only active capital takes the hit. When it wins, most gains get vaulted immediately.

This is how you let AI trade without letting it nuke the bag.
