NO Harley, unless you own outright share certificates (paid cash price for those shares), then buying shares on a margin, you allow that brokerage to do with them at their will, not yours !! TD has affirmed this many times to me over the years in writing in fact...
In plain English, you cannot lock your shares by simply putting in a GTC Order for a later date- it has no bearing. ONLY owned paper shares/certificates you can do such thing.. Hope this helps . :=)
