Where every number on the site comes from, how the cost of a trade is worked out, and what it can't tell you.

01 / Research we cite

01

02
Up to 33% less liquidity after the close
Order-book depth within 1% of the price fell about 19% on Bybit and MEXC and about 33% on Hyperliquid once US markets closed; cross-venue arbitrage didn't pay after costs.

03
Weekend prices called Monday right ~54% of the time

02 / Live data

Last real price: Chainlink price feeds for each stock token, read onchain (Robinhood Chain and Base). They update 24/5 with the market and hold the last price when it's closed.
Official tokens: Robinhood's public asset API (Robinhood Chain) and Coinbase's public tokenized-stocks API (Base; every official token's address starts 0xb200).
Your fill: KyberSwap's public aggregator: the best route across every venue on the chain, for your exact size. On Robinhood Chain we also quote the deepest Uniswap v3 pool with its QuoterV2 contract and show both.
The log: Every 10 minutes a Supabase scheduled job asks this app for a snapshot of every asset on both chains and stores it. The board, history chart and dot field read from it.

03 / How the cost is worked out

Selling: cost = (last real price − your fill price) ÷ last real price. It's the share of your money you'd get back less.
Buying: cost = 1 − last real price ÷ your fill price. It's how many fewer shares you'd get.
Drift is the same measure for a $1,000 trade; your size is the extra on top for your amount.
The call: under 0.3% is fair; 0.3%+ suggests a limit; 0.75%+ while Wall Street is closed suggests waiting; when your size causes most of the cost, split it; 20%+ means the market can't take the trade.
Protected swap: your worst fill is set at 0.3%, 1% or 2% from the last real price, and KyberSwap's router enforces it onchain. If the route can't meet it, nothing is built or sent.

04 / Limits

The last real price can be a day or more old on a weekend. Overnight news can move the stock before the open: a gap can be right.
Quotes are a moment in time; pools move. The protected swap exists for that reason.
Only assets with a Chainlink feed are covered (35 on Robinhood Chain, 13 on Base). Exchange holidays aren't modelled.
The weekend dollar estimate multiplies reported weekend volume by our logged average $10k cost. Real trade sizes vary, so treat it as an order of magnitude.
Not financial advice. Stock tokens aren't offered to US persons.
