The articles give no other numbers.\n#\n# What is NOT published and not verified against a live account: the social rating (the broker counts \"points\" for\n# actions, blocks a login for 2 hours when the limit is reached, and does not say the limit; a request for an order\n# that does not exist costs 100 points and a request that is not valid JSON costs 5000, a WebSocket connection and a\n# subscription cost 1), and on the futures market the counters of errors that the exchange fines. The limiter below\n# only keeps the plain request rate. Whether \"per user\" means per login (all portfolios of it) is read from the\n# article on the rating (\"counters are bound to the login\"), so one limiter should serve every connector of one\n# login, and the daily counters of the broker are not visible to it.\n#\n# One bucket of 100 a second for every HTTP method (the broker does not split them), a smaller soft bucket for\n# placements so that a flood of new orders can never use all of the budget and leave no room for a cancel.\n\n[alor.buckets.http]\n# All HTTP requests of one user: 100 a second.\nrate = 100\nper = \"1s\"\nburst = 100\n\n[alor.buckets.place]\n# Not a limit of the broker: placements (and replacements, stop orders) go through this bucket too, so that they\n# can never use all of the 100 a second.
