Past Ng chart, and the seasonals posted as a link.
When you click on the "Equity Clock Seasonal" it opens in a "new/second" tab and a single click will switch back and forth.
BUTTTT, this is not what you want either.
To get two or three charts on one screen, they have to be combined with a photo editor and still size within the Forum constraints of 200 or 300kb size.
Your full chart is 132 kb. So, if limit is 300kb as Rabbit mentioned, there is "room to combine two" one above the other. and use this approach for the seasonal chart, which doesn't line up anyway and is mainly for reference.
