We built the cleanest BTC Up/Down bot on Polymarket. We engineered the entire stack from scratch around one principle: never bet on outcomes, only capture mispricings. How it works: When YES + NO sums to less than $1.00 on Polymarket’s 15-min BTC market, the engine fires both... show more

@usePolyArb Few days in, pretty solid so far 👌🏼

🔥

@usePolyArb Any plans for ETH up/down or SOL up/down modules?

Yes, both on the roadmap. ETH up/down probably first Polymarket already lists those markets and the orderbook depth is similar enough to BTC that the same architecture ports cleanly. Targeting end of Q2. SOL up/down is trickier. Markets are thinner, depth caps the size we can deploy per trade. Probably Q3, possibly with a lower position cap to preserve fill quality.

@usePolyArb this is actually insane the fact that’s all automated make me feel I’ll def try it different game on polymarket with you

@usePolyArb 頭脳を使って、BTCの上下に賭ける方法はありません。代わりに、価格の過ちを掴むことに心血を注いでいます。捉えるだけでなく、正方向に賭けることはありません。それだけで利益が出ます。素晴らしいアーキテクチャーと効果的な方法です。

@usePolyArb Are you trading from London yet?

@usePolyArb Eh I’m skeptical. Tough to be faster than the MMs. How many contracts per buy?

@usePolyArb but because of fees this only works with limit orders, right ?

Mostly limit orders, yes. But the engine fires market orders when a mispricing window is closing fast eating the fee beats missing the trade. Routing optimizer picks per-trade based on net edge after fees. Anything below 30bps gets rejected.

@usePolyArb It's time to back test it

@usePolyArb Yeah this is kinda crazy

@usePolyArb I'm glad to see new players in the space! The key is definitely low latency for capturing those fleeting mispricings. Rust code + close proximity to the CLOB servers is really a killer combo for that edge.

Is this normal?

@usePolyArb polyarb cooking real alpha, this is smart 👀

Never bet on outcomes, only capture mispricings" is the entire edge in one line. Everyone else is still trying to be right about Bitcoin

@usePolyArb Good. Direction is for tourists. The spread is the paycheck.

@usePolyArb Capture-not-predict is the right frame. The next layer is cross-venue - when Kalshi quotes the same 15-min BTC contract 1-3 cents off Polymarket, the spread is risk-free if your fills are tight enough.

@usePolyArb custom RPC doesnt work, can you guys help?

@usePolyArb can i buy it?

Nothing to buy. PolyArb isn’t a product you purchase it’s an execution engine you plug into. Profit-share only

@usePolyArb im building prediction market looking for investors

@usePolyArb this is what smart money actually does

@usePolyArb 利用意図がよくわかります。凄いアイディアですね。

@usePolyArb What happens when that gap closes?

@usePolyArb bags getting heavier now about to move fast

neat principle

@usePolyArb this base keeps getting defended sell pressure getting absorbed on red

right, single-venue arb on liquid markets is essentially a market-making fight. cross-venue arb on the same outcome stays open way longer because each venue has its own price discovery process. the only catch is making sure you're really trading the same outcome and not slightly different contract specs

@usePolyArb this is wild capture mispricings at ~97c per trade. how sustainable with fees?

@usePolyArb We see you

@usePolyArb You’re saying the 15m up down is still raking it in since earlier this week?

Your selected RPC is not responding to any requests. Try changing your RPC.

@usePolyArb do we have any docs to read?

@usePolyArb watch what happens next when it gets traction the script is playing out and the herd follows late

@usePolyArb clean setup. atomic capture + tight detection window is where the edge is. once you’re already at ~100ms, the next gains usually come from routing and landing consistency — happy to help push that further if you’re exploring.

@usePolyArb bag check: heavy and bullish every dip gets met buyers keep stepping in
