I use Dukascopy as my broker. I get a quick response from the agent. The only problem was when signing up it was a tedious process of mobile phone verification and document uploading. Otherwise, I am happy with them after two months of use
Yes, this is a trusted broker. This is why we have added them to the Trusted Brokers page (many students gave us good feedback about Dukascopy). I am using them as well mostly because of their Historical data, and the Forex Historical Data app works with the data they provide.
With some brokers, it is a headache to go over the verification process, but this is a sign of a legit broker. The scam broker would take your money first, and then they would ask for documents, so you can’t refund.
Anyway, I would appreciate it if you have any other feedback, so we will keep on the Brokers Page the most reliable brokers, and we will keep the students and the traders away from the scammers.
