Un glissement positif signifie que la transaction a \u00e9t\u00e9 ex\u00e9cut\u00e9e \u00e0 un meilleur prix que pr\u00e9vu, tandis qu'un glissement n\u00e9gatif signifie qu'elle a \u00e9t\u00e9 ex\u00e9cut\u00e9e \u00e0 un prix moins bon. Le glissement se produit parce que les prix \u00e9voluent continuellement, et que le temps entre le placement d'un ordre et l'ex\u00e9cution de l'ordre est suffisant pour que le march\u00e9 change, en particulier sur les ordres plus importants ou pendant les conditions volatiles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Les causes les plus courantes sont la volatilit\u00e9 du march\u00e9 autour des \u00e9v\u00e9nements d'actualit\u00e9, la faible liquidit\u00e9 sur des instruments sp\u00e9cifiques ou \u00e0 des moments sp\u00e9cifiques, et les tailles d'ordres plus importantes qui ne peuvent pas \u00eatre ex\u00e9cut\u00e9es \u00e0 un seul niveau de prix. Un stop loss d\u00e9clench\u00e9 lors d'un mouvement de march\u00e9 brusque peut s'ex\u00e9cuter \u00e0 plusieurs points du prix stop si la liquidit\u00e9 est faible. Les publications \u00e9conomiques programm\u00e9es, les d\u00e9cisions des banques centrales et les nouvelles soudaines cr\u00e9ent souvent de courtes fen\u00eatres o\u00f9 le glissement est significativement plus \u00e9lev\u00e9 que la normale.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Le glissement peut affecter un compte de soci\u00e9t\u00e9 de prop trading de deux mani\u00e8res importantes. Premi\u00e8rement, il peut entra\u00eener l'ex\u00e9cution des stop loss \u00e0 des prix moins bons que pr\u00e9vu, produisant des pertes plus importantes que celles que le trader avait l'intention de subir. Deuxi\u00e8mement, ces pertes plus importantes peuvent pousser le compte plus pr\u00e8s de la limite de perte quotidienne ou du drawdown maximal, et dans certains cas, d\u00e9clencher une violation.<\/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-6421","glossary","type-glossary","status-publish","hentry","glossary-category-trader-glossary"],"acf":{"target_keyword":"slippage","glossary_post_image":"","key_takeaway":"Key Takeaway","key_takeaway_description":"Slippage is the difference between the expected price of a trade and the actual execution price. It is most pronounced during volatile conditions, news events, and on illiquid instruments. ","faq":"<b>Is slippage always bad?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">No. Slippage can be positive or negative. Positive slippage means the trade filled at a better price than expected. Negative slippage means it filled worse. In practice, negative slippage is more common on stop-loss orders during fast moves, while positive slippage happens occasionally on limit orders when the market jumps favorably past the limit price.<\/span>\r\n\r\n<b>How can traders reduce slippage?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Using limit orders instead of market orders is the most direct way to control execution price, though limit orders also carry the risk of not filling at all. Avoiding trades around major news releases, trading more liquid instruments, and using smaller position sizes all help reduce the likelihood of meaningful slippage.<\/span>\r\n\r\n<b>Does slippage count against my drawdown?<\/b>\r\n\r\n<span style=\"font-weight: 400;\">Yes. If a trade executes at a worse price due to slippage, the resulting loss counts toward the account's drawdown just like any other loss. This is one reason why planning position sizes with some tolerance for execution variance matters, particularly if the strategy involves holding through volatile periods.<\/span>"},"_links":{"self":[{"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary\/6421","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=6421"}],"wp:term":[{"taxonomy":"glossary-category","embeddable":true,"href":"https:\/\/propaccount.com\/fr\/wp-json\/wp\/v2\/glossary-category?post=6421"}],"curies":[{"name":"WordPress","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
