Hi Sinner,
Your equity and future chart looks quite interesting. Can you explain what you mean by your last line? Where on the chart will you go long/short the correlation? Actually, is there a correlation if you are just going long/short straddle on a single stock?

I think you don't understand what I wrote.
I don't go long or short "the correlation" and the chart is not a chart of correlation, it is a pair of instruments (each chart is a different pair of instruments) which form the basis for a trading model, long or short of which depends on implied correlation (and a few other factors).
What I "meant" is that I prefer to place the same trade as the OP on models which make much more sense to place those sorts of trades on, because then you really are betting on only one thing (correlation returning) rather than two things (correlation returning and cointegration remaining high).
