what is this type of stock trade?

try to sell if today's google stock goes above 669$ this is relative/pegged-to-primary order with a limit price of $669 and an offset from national best offer of $0.00, but it is no different than an market order if the market price is $669 to begin with.  do not sell if the stock keeps climbing beyond 669 unless there is a down tick of 20cents is seen this is a trailing stop order with a trailing amount of $0.20. it sells if the market price dropped $0.20 from the peak.  the two orders are contradictory. from your comments, i think the following is what you want: submit trailing stop order when market price is above $669.  cancel trailing stop order before the end of the day and submit relative/pegged-to-primary order to sell.
