I will move to Switzerland soon and I don’t find any broker offering full access to American OTC markets.
Only IB and Saxobank seem provide Pink Market access but not to others OTC Markets.
Cornertrader and Degiro don’t provide any access to OTC markets.
I find on Google unionsecurities.ch but their website is shady and almost empty : there is no pricing nor detail of which markets they cover.
Do you know if there is any trustworthy broker providing full access to American OTC Markets in Switzerland?
