In France, all forex and CFD brokers are regulated by both the national regulator known as Autorité de contrôle prudentiel et de résolution (ACPR), and the EU-wide European Securities and Markets Authority (ESMA). This means that all EU regulations concerning forex & CFD trading applies in France, including the strict limitations on trading leverage that the ESMA has introduced.
Forex trading is popular in France, and many brokers there offer the classic MetaTrader 4 (MT4) platform to their clients. This is a powerful trading platform designed to give users full control over everything from designing trading indicators, to backtesting strategies, and perform chart analysis. Most remarkable, perhaps, is that the MT4 is still relatively unique in this sense among retail-focused trading platforms, despite being released all the way back in 2005.
