Giving an LLM direct execution authority is an incident waiting to happen. Decouple execution autonomy from capital exposure with deterministic, LLM-free risk gates. Here's what broke and how I fixed it: https://t.co/aeDfyYpNCy

🔍 What if your edge isn’t in another indicator… but in understanding how the market feels?

I’ve been exploring LLMs for sentiment analysis—not because they’re trendy, but because context matters.

Not saying this replaces your edge.
But maybe it sharpens it.

Better signals. Fewer false flags.

I was charged a $25 fee after a Dasher couldn’t figure out how to scan my valid ID — even though I complied with all delivery rules. I only got $4.66 back and now support won’t respond. I’ve filed a complaint with the Georgia AG's office. @DoorDash_Help @DoorDash
