# Markets and trading

> Market structure seen on-chain and in filings: spot ETF flows, exchange balances, whales, unlocks, perpetuals, liquidations and sentiment.

Markdown copy of https://voltfincrypto.com/topics/trading

Market structure leaves marks on the chain: coins moving to and from exchanges, large transfers, liquidations and perpetual funding. The apps here read those flows from the chain, and record off-chain figures such as spot ETF holdings with the source file they came from.

None of it is a signal to buy or sell. Each app defines what it measures and shows its receipts, so a reader can judge the data for themselves.
