TRIP popped at 12:33 PM ... not sure if the scanner would have picked up on it, but it surely would have seen 12:37 PM.

As I've said time and again the one minute chart is not particularly useful for seeing where you could realistically enter and place stops, you need a tick chart for that, and my buddy @HCPG kindly provided me with two ten tick charts below:

You can see that it would have been tough (for the scanner) to spot between 12:32 and 12:37 ...

It's during the 12:37 bar that activity really picks up and it would be sounding multiple alarms ... even with a "bad" entry of $79 (better at $78) things would have worked out into the close, risk versus reward worthwhile (said with the benefit of hindsight).

StockTwits stream, usual suspects NewsHedge_Squawk and OpenOutcrier ... Moench first to notice at 12:34 which gives me hope that the scanner would have bleeped, beating the pack.
