Three weeks ago at the Paris Trading Convention (*Salon du Trading*), I took part in something that hadn't happened in the event's 20-year history. I entered 5 autonomous AIs into their famous Live Trading Duels against professional discretionary traders.
The setup:
\- €50k starting capital per account, live markets
\- 3 rounds of 1 hour each: Equities, FX/commodities, Index futures
\- No code changes allowed once a round started
\- 5 models with different logic (momentum, mean-reversion, trend continuation, etc.), running fully autonomously with their own capital. I didn't touch a keyboard.
While the human traders were glued to every tick, watching the order book and feeling the pressure, I literally sat there eating a sandwich and checking notifications on my phone (see photos). I didn't open a trading platform or click once. The models (called Blitz, Ronin, Guardian, Spark, and Iceberg) handled everything for me.
Here's how the day actually played out:
**Round 1: European Stocks (9:30 AM)**
Ronin shorted TotalEnergies (TTE) on a \~1% downtrend break. Blitz scaled into Louis Vuitton (MC) longs on the session trend. Humans spent most of the round hunting liquidity pockets and hesitating on entries. Afterwards, a few people in the audience came up to me and said: "They're going to hate you for doing nothing while they sweat."
**Round 2: FX & Commodities (2:00 PM)**
This round was a pressure cooker. The room was packed, and a live commentator was calling the action like in a boxing match. You could clearly see the human traders feeling the stress. Gold was the main vehicle for most traders.
Blitz shorted it and caught a nice downward momentum move, making all its profit early before sitting out. Guardian also traded gold but played the bounces, taking buy trades at completely different timings. Iceberg, however, took zero trades and got disqualified for the round.
**Round 3: Indices (5:00 PM)**
By the final round, everyone was exhausted from the cognitive load of scalping/day trading (and of the event). Everyone except AI, of course.
The Nasdaq futures were stuck in the middle of their daily range, directionless. Human traders explicitly said the ideal short window was gone.
AI disagreed. 3 minutes into the round, Guardian shorted the market and rode a downtrend that lasted almost the entire session. 4/5 models shorted the Nasdaq and took profits at different times. Iceberg stubbornly tried to buy for mean reversion and took a loss.
The most interesting part? Blitz knew it was leading the overall competition. It took its profit early and simply stayed out of the market to protect its lead. That wasn't a hard-coded rule.
**The Final P&L**
Every single one of the five models ended the day in profit:
1. Blitz: €1,380
2. Ronin: €647
3. Guardian: €460
4. Spark: €346
5. Iceberg: €140
Blitz and Ronin each beat the top human P&L of the day.
**What I found interesting from a systems angle:**
\- Two models trading the same instrument took near-opposite positions at different times, so "intra-fleet" correlation stayed low even on the same asset.
\- The "stop trading when ahead" behavior was emergent, not scripted.
\- Humans visibly degraded across the 8-hour day. AI doesn't.
**Caveats I want to be upfront about:**
\- N=one day. I am not claiming this generalizes. I'm still doing R&D on fully autonomous AI-based trading.
\- Small sample of human opponents (though professionals), not a controlled comparison.
Watching machines out-trade exhausted pros live was a wild experience, especially while eating a sandwich 🥪 The audience also loved it. Happy to get into the model architecture, feature set, or risk logic in comments.
