I did this for the SPX and wanted to loop back around to TVIX.
Just popped in and really crazy the indicator pattern repetition we're seeing.
Maybe it's just coincidence but it's something to consider.
Based on this model spike would come sometime between early July and mid August and based on everything else I know I think it's likely we get two spikes, a smaller one in July and bigger one in August, so could be both.
Lets let this play out and see!
