After reading http://forums.civfanatics.com/showthread.php?p=9692207#post9692207 I had this fought
Not every city has a stock exchange (a lot of countries don’t have their own) so I was thinking should be stock exchange building with a national wonder (I think civ 5 still has them)
That gives
+33%
in all cities
And
When you are making more than 10gold profit
+10%
in all cities
+1
per city
+1
in all cities
When you are making between -5 and +9
+0%
in all cities
+0
per city
+0
in all cities
When you are making between -6 and lower
-10%
in all cities
-1
per city
-1
in all cities
Any one got any thoughts or ideas?
