Chart for Friday and today (assuming you're reading this on Monday). Friday is the left pane, today is the right pane. This is a DYNAMIC chart which changes, so if you're just catching up on Tuesday. the the right pane is TUESDAY and the left pane is Monday.
Anyway, look at those long stretches without a trade, then BOOM.
