I installed the IB platform and I use a simulated trading account. I find the platform quite confusing. I placed in total about 10 transactions and although I tried to close all of them, my P&L still varies. In Portfolio, under My Investments it only shows USD Cash. Under MGKS Asset Management, there are $3556 and there are two sub-entries named MrktCpTp10Bttm0 and Independent, each with some amount. Is there a way to close these positions (in case they are open).
Also, is there a way to simplify the platform, by allowing only standard shares transactions (no options or other complex things)?
Any advice appreciated.
