What’s the best way to build a solid forex-learning foundation?

For me, risk management and position sizing come first. You can have a great strategy, but if you don’t understand how much you’re risking on each trade, leverage and a few bad decisions can wipe out your progress quickly. After that, I’d focus on market structure, support/resistance, and then build into fundamentals and backtesting. Biggest beginner mistake: trying to make money before learning how to protect capital. Learn the mechanics, practice on demo, journal everything, and keep risk consistent.
