Marcus Feld has spent 13 years inside retail CFD and forex markets, first on a Frankfurt dealing desk and later as an independent broker reviewer. He treats every broker like a recipe, stripping away the marketing dish to weigh the raw ingredients underneath: real spreads, real execution and real regulation. He has evaluated more than 60 CFD providers across FCA, ASIC and CySEC jurisdictions and leads the testing standard behind every InvestingChef verdict.
Marcus tests each broker on a live funded account. He records entry and exit spreads across peak and off-peak hours, measures slippage on stop-loss orders under varying liquidity, and watches platform stability during scheduled high-volatility events such as NFP releases and central bank decisions. Every spread figure in an InvestingChef table comes from this live process, never from broker-supplied marketing numbers.
