The platform drops you back to the login screen without warning, sometimes while a trade is running.
A session timeout, a second login elsewhere, or a dropped connection. The position itself is unaffected by your session ending.
Your session is only your right to view and command the account. Orders, positions, stops and targets live on the firm's servers and keep working when your browser does not. This is good news during an outage, but it also means a stop you intended to place, and did not, does not exist anywhere.
Short session lifetimes are a security decision by the firm rather than a bug, and they are common on funded accounts.
After logging back in, the open position shows the same size, entry price and attached orders as before the disconnect.
Attach a stop loss at the moment you enter, not afterwards. Keep the platform in a browser window you do not close, and avoid running the same account in two places at once.
