Cela se produit lorsque le march\u00e9 \u00e9volue \u00e0 l'encontre des transactions ouvertes et que les pertes r\u00e9duisent les capitaux propres du compte en dessous de la marge minimale requise pour maintenir ces positions ouvertes. Si la marge n'est pas restaur\u00e9e, la plateforme ferme g\u00e9n\u00e9ralement automatiquement tout ou partie des transactions ouvertes pour ramener le compte dans une zone de marge acceptable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dans le trading de d\u00e9tail, un appel de marge signifie souvent que le trader doit d\u00e9poser plus de fonds pour maintenir les positions. Dans le contexte d'une soci\u00e9t\u00e9 de prop trading, cette option n'est pas disponible. Le solde du compte est ce que la soci\u00e9t\u00e9 a allou\u00e9, et les traders ne peuvent pas y ajouter de capital. Lorsque la marge devient faible sur un compte financ\u00e9, le niveau de stop-out de la plateforme prend le relais, fermant les positions pour prot\u00e9ger le solde restant. Le niveau de stop-out est g\u00e9n\u00e9ralement d\u00e9fini \u00e0 un pourcentage sp\u00e9cifique d'utilisation de la marge, souvent autour de 50%.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Le moyen le plus fiable d'\u00e9viter un appel de marge est un dimensionnement conservateur des positions associ\u00e9 \u00e0 des stop loss sur chaque transaction. Parce que les appels de marge dans un environnement de soci\u00e9t\u00e9 de prop trading d\u00e9clenchent des fermetures automatiques de positions, ils peuvent \u00e9galement d\u00e9clencher des limites de perte quotidiennes ou des d\u00e9passements de drawdown maximum selon la fa\u00e7on dont les pertes affectent le compte.<\/span><\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"glossary-category":[131],"class_list":["post-6407","glossary","type-glossary","status-publish","hentry","glossary-category-trader-glossary"],"acf":{"target_keyword":"margin call ","glossary_post_image":"","key_takeaway":"Key Takeaway","key_takeaway_description":"A margin call is a notification that an account no longer has enough available margin to maintain its open positions.

","faq":"<b>Can I deposit more funds to avoid a margin call on a funded account?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">No. Funded accounts are provided by the prop firm, and traders cannot add their own capital. When margin runs low, the platform closes positions at the stop-out level to protect the remaining balance.<\/span>\r\n\r\n<b>What is the stop-out level?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">The stop-out level is the margin percentage at which the platform starts closing positions automatically. It varies by firm and plan but often sits around 50%, meaning positions begin closing when the account's used margin exceeds half of the available equity.<\/span>\r\n\r\n<b>Does a margin call fail the challenge?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Not directly, but the position closures triggered by a margin call can. If the losses from the closed positions push the account past the daily loss limit or maximum drawdown, that is what fails the challenge, not the margin call itself. Traders who reach a margin call have usually taken positions too large for the account they are trading.<\/span>"},"_links":{"self":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary\/6407","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=6407"}],"wp:term":[{"taxonomy":"glossary-category","embeddable":true,"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary-category?post=6407"}],"curies":[{"name":"WordPress","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
