Hi,
in general, we contribute pretty serious weight to the analyzer functionality. But it contains a lot of data, so it depends, what types of pairs are you interested in.
If you just want to trade mean-reversion, you should really check the cointegration and residuals.
If you want to run just one-way arbitrage (i.e. long-only pair positions), you don't need to look at cointegration at all.
In any case, look at profit analysis - you can see the distribution of profits over models and parameter.
Cointegration is NOT a necessary condition for pair to be worth to trading, however it is quite interesting indication that it may be.
At this moment we are implementing new database system with millions of pairs using also the cointegration. We will use it to make a research of how exactly cointegration is affecting out-of-sample pair trading performance.
We are sorry there are no tutorials of how to use all the data seen in the analysis (cointegration, residuals, PACF) yet, because we are really focused to development now. However, we will definitely make some in few months. For the time being please search over the internet for cointegration based pairs trading, you will definitely find something useful.
