Multiple regulatory disclosures and broker-published statistics consistently show that a large majority of retail forex traders lose money over time, and understanding why matters more than any specific strategy.
Leverage is a major factor — forex trading commonly offers high leverage ratios, which amplifies both gains and losses, and undisciplined position sizing relative to account size is one of the most common reasons accounts get wiped out quickly.
Overtrading, driven by impatience or chasing losses after a bad trade, compounds the problem — trading frequency itself does not generate profit, and excessive trading mainly generates transaction costs.
This is not a reason to avoid forex education entirely, but it is a reason to treat risk management — strict position sizing and predetermined stop losses — as the actual core skill, well before worrying about entry signal strategies.
