To me it looks like these guys are running scripts that check the status of each ticker and then when it changes from false to true they send out an update on telegram or whatever platform.
Here is part of the code that pertains to it:
Sf = function() { var e = Lt(es.a.mark(function e(t) { var a; return es.a.wrap(function(e) { for (;;) switch (e.prev = e.next) { case 0: return e.next = 2, us.request({ method: "get", otcAPI: !0, responseFormat: "data", url: "/company/hasIqAccount/" + t }); case 2: return a = e.sent, e.abrupt("return", a.data); case 4: case "end": return e.stop() } }, e, this) })); return function(t) { return e.apply(this, arguments) } }(),
