I agree 100% on the week-end days for the Bourses.
All these events in Europe do always take place only on weekends: that is
true for France, Natherlands, Belgium, Italy, Germany, Spain and so on. In
fact, in these days most people are free to move away from work and to
consacre the time left after the religious service of their 'church', to
their favourite hobbies.
