Buy Stop orders without knowing volume

Hey Pat thanks for your energy and positivity!  When i am out working throughout the day i have a hard time keeping up with the trigger prices and volume.   In an ideal world i would pick a handful of stocks off the key list/maxlist and put buy stop orders in with a couple contingent sell stop orders, and not really check on anything until i get home from work.  However with how important volume through the pivot is, i am finding that it doesn't make sense to put those orders in pre-market without knowing if the volume is there.  Any suggestions? Thanks
