Buying calls at monthly Support!

I plan on buying calls at the 167.16 monthly support level. I would have wanted to buy in at the 172.29 weekly level but there just so much downward pressure that it ripped right through that weekly level. Should have a nice reversal at this 167.16 monthly level. I plan on buying a little after the level is reached to ensure the bottom.
*THIS IS ONLY A GAME PLAN* if the level is never reached than no harm no foul :)
