Entered on Opening Range Break. Just after entry we were tied up at the Retreat and my computer was updating/loading. It dropped down to around $3.60 and then went on a consolidation pattern sideways. Since it was going sideways I set a S/L at $3.50 which it never hit. Around 2:00 it started a run up to $3.94 and I needed to walk away. Ultimately set a S/L hard stop at $3.70 which it dropped to while we were in meetings. Acceptable given all of the things going on.
