# Markets and feeds > Index pools on any EVM chain or Solana, read every Hyperliquid, Lighter and Polymarket market, use free shared feeds, and follow order books and listings live. ## Pools on any chain Add a pool on the Sources page (or with `add_pool`) by its address and chain, and ftw.trade starts indexing it, reading back as many hours of history as you ask for. - **EVM chains**: Robinhood Chain, Ethereum, Base, Arbitrum, Optimism and Unichain read through ftw.trade's hosted RPC; add any other EVM chain with your own RPC URL. Uniswap V2, V3 and V4 pools, and Metric pools. - **Solana**: PumpSwap, Raydium (CPMM and CLMM), Orca Whirlpool and Meteora DLMM pools. A pool has bars of 5s, 15s, 1m, 5m, 15m, 1h, 4h and 1d, built from its swaps. A strategy on a pool steps each bar the moment the pool has been read through it, about 5 to 7 seconds on 5-second bars. It can also read every swap: side, amounts, price, trader and transaction. `bars.usd(market, interval)` is each close in dollars (a pool quoted in ETH or SOL is converted at that coin's price when the bar closed), so a market cap is `bars.usd(…) * supply`. ## Perps and spot on Hyperliquid and Lighter Every Hyperliquid and Lighter market is listed under **Markets → Perps & spot**: perps, Hyperliquid's builder perps (stocks, gold and more, like `xyz:TSLA`) and spot pairs. Add one to your sources and read it as `perp::`, with its funding rate. ## Prediction markets Every open Polymarket event is under **Markets → Predictions**. Each outcome is the series `poly:`, its price the probability from 0 to 1, with nothing to add. Every trade as it prints is on the `trades` stream. ## Shared feeds Crypto, stocks, commodities and lending rates, streamed once for every account and free: Coinbase, Kraken and Chainlink prices, and more. Strategies read them as `feed:` (1-minute bars and up). ## Order books Any Hyperliquid, Lighter or Derive market's book, or a Polymarket outcome's, can be read now or followed live: - **Now**: the book's levels, from the market's page or `get_order_book`. - **Live**: a source on the `books` stream sends each change at most once a second, with best prices and sizes, microprice, spread, depth within 0.1% to 1% of the middle, imbalance and the top 10 levels each side. - **History**: record a book every 15 seconds for strategies to backtest on. See [Order book strategies](https://docs.ftw.trade/strategies/order-books). ## New and closed markets **Markets → New & closed** lists every Hyperliquid, Lighter and Polymarket listing, delisting, closing and resolution, checked every 5 minutes. The `markets` stream sends each as it happens, so a workflow can act on a new listing, and a strategy on a market that goes away stops, saying why. ## Liquidations On Hyperliquid's largest perps, ftw.trade records where real open positions would be liquidated, a minute at a time. Strategies read it with `liq.*`, and the charts draw it.
