Large block trades Meaning

Transactions involving a massive amount of an asset, executed outside of the public order book. These are typically performed via "Over-the-Counter" (OTC) desks by institutional investors, whales, or miners who need to move significant capital without alerting the broader market.

If a large block trade were executed on a standard exchange, it would likely clear the entire bid side of the order book, causing a "flash crash." By using a private match-making service, the buyer and seller can agree on a fixed price for the entire block, ensuring "price certainty" for both parties. These trades are often reported to the public with a delay or appear as large "on-chain" transfers between unknown wallets.

Analysts track these "whale movements" to gauge institutional interest; if large blocks of an asset are being moved from exchanges to private wallets, it is generally interpreted as a bullish sign of long-term accumulation.
