SPY, buying a call when it gets to 180.5

Updated
I plan on buying a call on spy when it hits 180.5, It has support levels that go back over a year many times it has bounced off this level. I do not think we will end up dropping below this level but not at first. I plan on buying a call at 180.5 with a .20 trailing stop loss
Note
replace 180.5 with 280.5 in every instance of the post. lol.. my bad
