For basics Id keep it boring on purpose.
Use Investopedia for definitions. Use broker education pages for order types, margin, stops & position sizing. Use plain charting material for candles, trend, support, resistance, ranges, volume & session behavior before advanced language starts sounding like a shortcut.
The order matters more than the brand. Learn what a candle is. Learn what a range is. Learn why highs & lows matter. Learn what liquidity means in plain English. Learn how stops work. Learn why position size can kill a good idea. Learn what invalidation means before any setup starts looking important.
Then paper trade one simple setup & journal it. Entry reason, wrong point, stop, target, result & mistake. Repeat until the pattern starts showing you where your own brain keeps lying.
The safest early material teaches mechanics without trying to make you believe the teacher is a wizard.
