<@378727998121181184> think you might've been onto something with the latency lol My bot is finding much fewer "profitable" moments, but is seemingly way more accurate now.

What are the scams people are running in here? I already got like 5 friend requests from "Kalshi Support" when I joined the discord lol

I had a 100ms delay baked in so it was fine, but now I gotta worry about how much data I'm storing because it basically 5x'd the sample rate.

Either you're doing something wrong (too many subs or bad commands) or you're not replying to heartbeats...or you're getting rate limited.

<@378727998121181184> put a basic stopwatch on my main loop...latency is ~190ms right now, but can heavily reduce it with a binary search enumerating 700k rows of data is kind of a performance hit lolol

That being said though...if you're not making +$400/month on your bot, why are you running it in the first place? 😛

Not hard to up the docker container to AWS. No reason to pay for a box when I'm still debugging it all.

Are y'all running the tightest boxes possible? lol Otherwise, RAM/memory concerns are moot in 2026.

It's a .NET channel made for multithreading. It's basically free. There's no serialization at all.

I guess you can get sub ms net latency if you host a box in the same aws region

What's your latency to the servers then? lol

I'll measure my actual latency though eventually. It's definitely low enough for what I'm doing.

Idk how you'd have the rate limit to manage microseconds worth of orders. You're still gonna have ms level latency over the net to kalshi.

I don't see the appeal of using multiple boxes. Just beef up the one box and spread the threads.

You only have to do that once unless your doing it over the net. If it's same box, then there's no packing at all. + you can use something like grpc or roll some custom binary serialization for pretty cheap

Packing in what sense? Serialization?

It might even contain last price after close. You can check on a closed market to see if it's filled.
