Sammy, FSC can plot $NYAD also, but I do not believe that FSC can do two plots with actual values. But I don't see this as a problem. SSO was only on the chart for reference, it was not used in the signals.
Based on the notations on the chart, he clearly notes the buys and sells based on SStoc, Will, and the $NYAD. Don't know which of the three or how he used the three to make a final decision. If you know that the SStoc and Will are conformations, okay.
