true, true, true etc..... ur choice and split em up whatever ya like (just apportion brokerage buy fees appropriately across the parcel if you split a parcel)
some xtra idle thoughts to mull: most brokers use fifo to calculate cost base (profit/loss) and some do not allow editing of cost base... so it can get confusing on ur platform if u do not keep good independent records (like excel....) to do ur tax and keep track of things.
if u r carrying an existing (roll-over) tax loss then 50% does not apply.
