Beyond the banks, large non-bank market makers and specialized firms also act as LPs, particularly in retail markets.<\/span>\r\n\r\n<b>How does liquidity affect spreads and slippage?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Deep liquidity means more buyers and sellers at or near the current price. Tighter spreads result from this, and slippage during normal conditions tends to be minimal. When liquidity thins out, such as around news events or in low-volume sessions, spreads widen and slippage increases regardless of which LPs the firm uses.<\/span>\r\n\r\n<b>What does tier 1 mean in liquidity providers?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Tier 1 refers to the top category of liquidity providers, usually major global banks with the largest balance sheets and the widest access to interbank markets. These institutions quote the most liquid currency pairs around the clock and are the ultimate source of liquidity for most forex trading. Tier 2 and tier 3 providers typically source their liquidity from tier 1 banks and pass it through to brokers and prop firms with additional handling.<\/span>"},"_links":{"self":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary\/6513","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/types\/glossary"}],"wp:attachment":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/media?parent=6513"}],"wp:term":[{"taxonomy":"glossary-category","embeddable":true,"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary-category?post=6513"}],"curies":[{"name":"WordPress","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
