Watching $BA around 215.36

Boeing has been an interesting one to watch lately, and I'm particularly keyed into that 215.36 level, which seems to have offered some decent support on intraday dips. If we start seeing sustained closes below that, especially on any significant volume, my bullish conviction would certainly take a hit. It's not a hard line in the sand, but it's where I'd reconsider my bias given how the price has reacted there recently.
