We get the data from Lang & Schwarz, a company providing the electronic trading system and taking the market maker role at the Börse Hamburg (Hamburg Stock Exchange, Germany). Between 9 a.m. and 5.30 p.m. (standard trading hours) the data/ stock prices are close to XETRA as Lang & Schwarz prices/ quotes are referenced to XETRA. Only from 7.30 a.m. to 9 a.m. and from 5.30 p.m. to 11 p.m. (outside standard trading hours), prices may vary and spreads are greater.
