Dumb ass it's a future contract. Not an equity. And funny, you don't understand probability theory. You don't win in trading, no one does without intel. Let me guess you are a pro trader or a moron that hangs out on this website that thinks he can trade and beat probability.
I have been around since 1998, so I know a few things. Like you complaining for not clicking this: WHO IS YOUR BROKER??? If $6K is worth suing someone, you should NOT be involved in trading...
Are you now trying to say there is no such thing as GTC and day orders in the futures market while calling me a dumb ass? https://www.cmegroup.com/education/courses/things-to-know-before-trading-cme-futures/futures-order-types.html#:~:text=Typically, futures orders are submitted,order does not get filled.&text=These orders are typically called,or the order is filled. https://prnt.sc/12va4t0 Too bad you didn't lose your entire account, you really did deserve it.
Silver is not very liquid overnight, so a default order time of regular trading hours might not be a bad idea.
SI regular trading hours are Sunday - Friday: 00:00 - 17:00 18:00 - 23:59 ET so I doubt this was the issue. Unless IB defines the regular hours for SI different from the CME. It seems more likely that time in force was day instead of GTC.
Another quote, dumb ass. This time from IBs website directly. "Time in Force for Orders The time in force for an order defines the length of time over which an order will continue working before it is canceled. We support the following time in force options: DAY - A Day order is canceled if it does not execute by the close of the trading day. Unless otherwise specified, every order is a Day order. GTC - A Good-Til-Canceled order will continue to work within the system and in the marketplace until it executes or is canceled by the customer."
