As someone who approaches broker selection with strict caution, I found that Marex Spectron positions itself as a major market maker, providing liquidity across commodities and financial markets, including foreign exchange. However, the available information from my research into their operations does not specify whether Marex Spectron offers fixed or variable spreads for forex trading. This absence of clear disclosure about their spread structure is concerning for me as a trader, especially considering the importance of transparent trading costs. Based on my experience with market makers and the context showing Marex Spectron caters primarily to institutional and professional clients via direct market access to liquidity providers, I would expect most spreads to be variable. Typically, with variable spreads, trading costs can widen considerably during high volatility or major news events—this is common industry practice, as liquidity can thin out and the broker has to adjust to market conditions in real-time. Moreover, there have been several user complaints regarding sudden and extreme changes in trading conditions—one in particular described a spread adjustment from $1 to $60 per pip, resulting in substantial unexpected losses. Such incidents reinforce my belief that spreads at Marex Spectron are not fixed and may be subject to significant, unpredictable widening during market events. For my own risk management, the lack of clarity and historical complaints about executions and withdrawal issues mean that I would proceed very cautiously, and I would require full written confirmation of spread policies before considering any real trading exposure with Marex Spectron.
