This may or may not help. I have TD Ameritrade. Couple of days ago I checked on my Unrealized gains/losses page. Under the symbol GN'H RTS 30.03.18 was a number of shares which was double my holdings. However I was not contacted in any way, it just showed up.
I'm not familiar with your brokerage, but honestly, just call them! I'm sure they will be happy to assist you if they think you'll be buying something & the call is free...
