CFD brokers and prop firms under the microscope

CFD brokers and prop firms are the most common route into trading in Poland – and across Europe. I've gathered in one place what can be verified in the sources: the Polish regulator's (KNF) registers, official data on how many clients lose, regulators' positions and a tax ruling. No affiliate links and no discount codes.

  A Polish licence, a branch, an EU passport notification and the warning list: what to check in 5 minutes before you send money.

  What's behind the “74% lose” figure, which rules the EU introduced and what they didn't change.

  What the automated accounts that sell signals, “account management” and “loss recovery” under videos and in live chats look like, how to spot them and what to do about them.

• Fake MetaTrader results: how people show profits that don't exist
  Demo accounts posing as real ones, cent accounts, servers where the owner types in the balance, multiple accounts and cut-out losses. Why it's usually gold, and how to verify a result.
