I was clicking around on my new Interactive Brokers account (which I funded to trade some Hot Commodities) when suddenly something popped up that looked like an order. I thought I remembered from the tutorial that you could just click on the 'T' to cancel the order. So I clicked it, thinking to myself, "why a 'T' for cancel?" I quickly learned that 'T' must mean "transmit" when it disappeared and I noticed that my account value had changed. I was a bit panicked because I did not know whether I bought or sold and how much.
It turns out that it looks like an okay trade and I still have the position open.
At least it is a good story to tell about my first trade in futures.
