ETH Reddit Mentions | ChartExchange

Posted this on WSB about an hour ago. It hit 3,067 upvotes and 200 comments, then the mods removed it. So here it is again for anyone who didn't get to read it.
I built an agent that buys whatever WSB is most talking about after the close. It is down 19.2% on the month.
Setup: 17 autonomous agents on a live account, up 15.2% on roughly $3,000, each with its own capital slice and its own strategy. No coordination between them, no human approving trades. 345 real fills over the month. Real broker, real money, not a demo account.
**The WSB agent**
It spreads a token amount across the most discussed tickers on WSB after the close. In August it bought MRNA at $176. Next session: $133. Down 24% overnight, and that single hold is essentially the entire month's drawdown for that agent.
It's a $10 position because I expected roughly this. The useful part is the agent did its job perfectly. It read the signal, sized correctly, executed on time. The signal was just worthless. Agent quality and signal quality are completely separate problems, and a good agent on a bad signal loses money very efficiently.
I keep it running as a control. If my other agents can't beat the one blindly following a message board, that tells me something important about the other agents.
**What actually worked**
Chip and AI-infrastructure basket, biggest allocation at $500, reweighted weekly on 60-day momentum. Currently holding NVDA, DELL, ANET. Up 22.9% for the month. Nothing clever in the construction, it just had the right universe in the right month. It also trimmed MU and SMCI before they gave back gains, which is easy to praise in hindsight.
**The earnings agent, and the trade I'm most impressed by**
It reads news and setup quality ahead of scheduled earnings, takes the trade only on favorable setups, and sits in VOO otherwise. On Aug 26 it sold VOO, bought NVDA near $210, held about a day, sold at $227 and went straight back to the index. Roughly 8% on a sub-24-hour hold.
**The headline-reaction agent, and a question**
It parses political posts and buys the large caps being praised. Worked example: news lands 2:31 PM ET that MU announced a $10B US research lab investment. The agent is filled in MU at $914.86 by 2:47 PM, sixteen minutes later. MU printed $936.81 the next morning, about +2.4%. It's still holding.
So here's what I can't decide. For an attention-driven signal, should the exit be time-based rather than signal-based? The whole premise is that a shout-out is an attention spike with no fundamental content. If that's true the position has a half-life measured in hours and the agent should sell into the next open mechanically. But then it has to be right about the fade horizon instead, and "exactly one session" is an arbitrary number with nothing behind it.
The earnings agent above is already doing the time-based version and it worked. I don't know if that's the right default or just the one that happened to work once.
**Coin Rotator: +77.9%**
The mechanic is stupidly simple. Hold exactly one coin at a time, whichever of 10 liquid coins ranks highest on momentum, volume and volatility. Re-check daily, rotate when the ranking changes. Zero diversification, on purpose.
It only moved four times all month:
* Held LINK, sold Jul 30 at $8.46 (bought at $8.37). Basically flat, +1.1%
* Into ADA at $0.1704, out Aug 8 at $0.199. +16.8%
* Back into LINK at $8.30, out Aug 18 at $9.50. +12.3%
* Into ETH at $1,912, out Aug 22 at $2,423. +26.7% in four days
* Into SOL at $93.87, still holding
Four completed rotations, four winners. The ETH leg is what actually made the month.
**Caveats**
* Real broker fills with real timestamps. Not a backtest, not paper, not a demo account.
* One month, 17 agents, one account. Nothing here is statistically significant and I'm not pretending otherwise.
* The two worst percentages sit on the two smallest allocations, which is a sizing artifact and not risk management working.
