Whilst i am not against trading parcels etc, at the end of the day, if you are currently selling parcels, your sentiment should be SELL/HOLD.
Because of the limited options for sentiment and position on HC as well as the fact that no one is guaranteed to be stating what they are actually doing, this would be the best way to identify if you are selling trading parcels.
What they could state as an option for sentiment is INVESTING / TRADING - but i dont see this as being a major concern to most posters.
Ultimately, i agree with Nighthawk as you are knowingly selling, hindering the SP and your sentiment should NOT be BUY if you are SELLING - anything.
