I have newly installed Ninja Trader on my computer, I have never used it before.
Whilst downloading it, instructions for simulation trading were sent to my email address and I followed them, as I wanted to open a simulation trading game, for my practice.
However, when I try to make a trade, say Market order for 1 x AAPL, on NASDAQ, it says;
'Select a valid account.'
Please help me.
Thanks!
