Market value is what the position is currently worth at the prevailing price. The difference between the two is the unrealized profit or loss on the position. A trader who buys at $100 and sees the price move to $110 has a market value 10% higher than the cost basis.<\/span>\r\n\r\n<b>Does market value affect my prop firm drawdown?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">It depends on how the firm calculates drawdown. Firms that measure drawdown against equity include the market value of open positions continuously, so unrealized losses move the account toward the drawdown limit in real time. Firms that measure drawdown against balance only apply the change once positions are closed.<\/span>\r\n\r\n<b>How is market value calculated for a leveraged position?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Market value is calculated on the full position size, not just the margin used to open it. On a $100,000 position opened with $1,000 of margin at 1:100 leverage, the market value is the current price of the instrument multiplied by the full $100,000 notional exposure.<\/span>"},"_links":{"self":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary\/6408","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=6408"}],"wp:term":[{"taxonomy":"glossary-category","embeddable":true,"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary-category?post=6408"}],"curies":[{"name":"WordPress","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
