The bottom of the area is of my making and is simply a 2.618 expansion of a major swing which lines up nicely with trend.
The upper line is a product Tony Caldaro, a widely respected EW technician who publishes OEW
And in the middle (2174) is a line developed by a gentleman who commented on one of my ideas with a simply outstanding chart.
Today the market got stymied with plain ole, basic support and resistance lines.
Longer term, we could be looking at levels in the 2250 area barring a fat tail risk.
