I'm trying to make a request of buy contract in a async ticksHistoryResponse, who is called in every response of the async ticksResponse. This ticksHistoryResponse function contains a condition that analyze the last 10 open, high, low and close prices of candles and the currently epoch, and make a buy request when all the condition are satisfied.
This function works good when i get in the computer and when i interact with it.
However, after a period of not interacting with the computer, the server responses are out of sync within 2 minutes, and the logs displayed on the console stop showing real-time information and show information from exactly 2 minutes ago. This causes purchase requests to be delayed.
I tried keeping tabs always on by enabling Chrome browser performance functions, but it didn't work. I'm calling the async functions through the await. Below is the script:
import DerivAPIBasic from "https://cdn.skypack.dev/@deriv/deriv-api/dist/DerivAPIBasic";

let connection;
function connect() {
connection = new WebSocket(
wss://ws.derivws.com/websockets/v3?app_id=${app_id},
);
connection.onopen = function (event) {
console.log("Conexão estabelecida:", event);
connection;
};
connection.onmessage = function (event) {
console.log("Mensagem recebida:", event.data);
};
connection.onclose = function (event) {
console.log("Conexão fechada:", event);
reconnect();
};
connection.onerror = function (event) {
console.error("Erro na conexão:", event);
reconnect();
};
return connection;
}
function reconnect() {
console.log("Tentando reconectar em 500 milisegundos...");
