The chart of cross-exchange rates needs to be finalized

It is required to program a graph of cross-exchange rates, more precisely, ready to take, clear from the source, add scripts and save data in the database, i.e. to establish its work according to a certain scenario, which I described in the tk.
In its current form, it works separately without reference to the site.

It is possible to work in 2 stages, the first cleaning and integration of the schedule into the site, the second stage is a scenario plan.
