This happens often. We don't stick to our guns and at the end we end up being right. For example: I called GLD earlier this week to hit and close the 167's gap, then I sell for small loss as it dipped and didn't seem to move and i thought "ok i'm wrong on this one, next!" and next day it suddenly rips and closes almost 169's today.
Weeklies are definately more risky - thats why its probably better to use smaller amounts of money for weeklies & more money for monthlies....although sometimes I don't even follow my own advice lol!
