for loop stops after 2nd case in Selenium - selenium

Question

I am working on a script that should just refresh trades every 15 minutes. It worked well, but then I found a problem. When it finds the trade that has to be refreshed.
else if (text[2] == "hours" || text[2] == "hour" || text[2] == "days" ||
text[2] == "day" || text[2] == "month" || text[2] == "months" || x >= 15)
It goes into the trade, edits it and saves as it should. But right after that it stops working. It says the program is still running, but nothing happens anymore. I have no idea why it would not work as it works perfectly for this case:
if (text[2] == "seconds")
continue;
I can't find a reason for loop to stop working to be honest. Would appreciate any ideas or tips.
Code:
private void CheckItems(IWebDriver driver)
{
IList<IWebElement>
trades = driver.FindElements(By.ClassName("rlg-trade-display-header")); // add all trades to list
for (var i = 0; i <= trades.Count; i++) // loop to check all trades
{
driver.Navigate().GoToUrl(tradeUrl);
if (i == 0)
Console.WriteLine("Active Trades: " + trades.Count);
var text = driver
.FindElement(By.XPath(
"/html/body/main/div/div/div/div[4]/div[" + (i + 1) + "]/div[1]/div/div/span"))
.Text.Split(); // reads text from trade and adjust it for the program
Console.WriteLine("Trade " + (i + 1) + " was last updated " + text[1] + " " + text[2] + " ago.");
var x = int.Parse(text[1]); // convert string to int to check time later
if (text[2] == "seconds")
continue;
if (text[2] == "hours" || text[2] == "hour" || text[2] == "days" || text[2] == "day" ||
text[2] == "month" || text[2] == "months" || x >= 15)
{
var element1 =
driver.FindElement(By.XPath("/html/body/main/div/div/div/div[4]/div[" + (i + 1) +
"]/div[1]/a/div"));
var actions1 = new Actions(driver);
actions1.MoveToElement(element1).Click().Perform(); // scrolls down to choosen element and clicks it
driver.FindElement(By.XPath("/html/body/main/div/div/div/div[2]/a[1]"))
.Click(); // click choosen element
var element = driver.FindElement(By.Name("btnSubmit"));
var actions = new Actions(driver);
actions.MoveToElement(element).Click().Perform(); // scrolls down to choosen element and clicks it
Thread.Sleep(2000);
Console.ReadLine();
}
}
}
private static void Main(string[] args)
{
var bot = new Program();
bot.setup(bot.driver);
while (true)
{
bot.CheckItems(bot.driver);
Thread.Sleep(15000); // wait 15 second before next loop
}
}
What I found out is that when I put a Console.ReadLine() in main after bot.CheckItems(bot.driver); it will now refresh all the trades and print everything for one whole for loop and then it stops and doesn't continue. And if I keep it like in code I given higher it works perfectly if all trades are in no need for refresh but if even one is it will refresh it and stop working. Any ideas what might be a reason for that problem? And why Console.ReadLine() matters?
