Methodology
Seledium.tech compares Robinhood Chain Stock Tokens to their underlying equities, identifying arbitrage opportunities between a stock token and its underlying security. This page explains exactly which numbers on the site are real, which are calculated from real inputs, and which are estimated or simulated using proprietary pricing models.
Live Data
LIVE- Robinhood Chain block height, block timestamps, and network status — read directly from the public Robinhood Chain RPC.
- Underlying equity bid/ask, daily high/low, and daily trading volume — from Robinhood's public Stock Token REST API.
- Stock Token asset metadata: ticker, name, logo, contract address, and current corporate-action multiplier.
- Onchain oracle price — Chainlink's Robinhood Tokenized Equity feed (latestRoundData()), read directly from its proxy contract. Note: this feed is defined as underlying price × multiplier, the same formula used elsewhere on this site, so it closely tracks the underlying rather than showing an independent market price.
- Underlying price chart history — recorded live on every poll going forward. Only the backfill from before this server started is simulated (see below); everything since is a genuine observed price.
- Memecoin price, 24h change, market cap, liquidity, and volume — from DexScreener, which indexes the real onchain DEX pools these tokens actually trade on. Unlike Stock Tokens, these are permissionless third-party ERC-20 deployments with no Robinhood registry, so there is nothing simulated on the Memecoins page at all.
Calculated Data
CALCULATED- Basis, basis points, and basis percent — derived from the token reference price vs. the real underlying reference price.
- 24h volume in USD — real share volume from the Stock Token API multiplied by the real underlying mid price.
- Rolling mean, standard deviation, and Z-score — computed from the (partly simulated) basis history described below.
Estimated & Simulated Data
ESTIMATED / SIMULATED- Stock Token market price and basis deviation — the real Robinhood Chain oracle/DEX price for a token's actual traded value isn't exposed by any public endpoint, so basis is modeled as a bounded, mean-reverting random walk around the real underlying price.
- Estimated liquidity — a slow-moving value loosely proportional to real volume, not a real order-book or pool depth reading.
- 24h change — approximated from a random walk scaled to the real intraday high/low range, since the public API doesn't expose a prior close.
- Underlying price history from before this server started tracking it, and the entire basis/token-price history — generated as a correlated random walk anchored to the real current price, since no historical Stock Token price feed is public.
- Opportunity Score — a simple normalized combination of basis magnitude, Z-score magnitude, and liquidity quality. It is an analytical heuristic, not a trading signal.
