Software developed for the NxCore API does not have to deal with the meticulous algorithms involved when switching to “real-time” processing from historic processing: the data always appears as continuous stream of quotes and trades.<\/li>\n<\/ol>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” equal_height=”yes” css=”.vc_custom_1544550321267{margin-top: 0px !important;padding-top: 35px !important;padding-bottom: 35px !important;background-color: #f9f9f9 !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column css=”.vc_custom_1544549595893{background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column_text]<\/p>\n
NxCore is Rich in Content<\/h2>\n
Every real-time quote and trade update includes additional valuable data elements immediately accessible by your software, saving significant CPU and memory resources, and development time. NxCore brings these elements to your software blazingly fast —\u00a05,000,000 quote\/trade updates per second on a 2.9 GHz\u00a0processor, using less than 400 megabytes of RAM.<\/p>\n
Each quote update includes:<\/span><\/strong>[\/vc_column_text][vc_empty_space height=”15px”][vc_row_inner css=”.vc_custom_1544551556180{margin-bottom: 5px !important;padding-bottom: 5px !important;}”][vc_column_inner width=”1\/2″]\n

An API that is designed to last, with zero or minimal changes; having already survived thousands of builds and many releases. First time developers have converted their software to run on NxCore in a matter of days, some had working prototypes on the first day. The dynamic Explorer-type NxCore API Viewer application shows the API’s\u00a0 ‘c’ structures update with each trade and quote data just as an application would see it, allowing developers to immediately grasp the fundamental concepts of the API.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-vz-jquery” bg_image_new=”id^3993|url^http:\/\/www.nanex.net\/2020\/wp-content\/uploads\/2018\/08\/background10-1.jpg|caption^null|alt^null|title^background10|description^null” bg_image_repeat=”no-repeat” parallax_sense=”30″ enable_overlay=”enable_overlay_value” overlay_color=”rgba(7,59,99,0.57)” css=”.vc_custom_1533917060989{background-color: #073b63 !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][vc_empty_space height=”50px”]
