I'd be careful trying to learn trading from youtube or investopedia. Actually I'd avoid it all together. There's tons of great information on both sites, but also equal amounts of garbage. Avoid TA, or if you insist on using it read "Evidence-Based Technical Analysis" which will give more insight into how to actually judge the value of TA methods (spoiler: most simple methods like macd cross over are garbage). Put 90% of your capital into a hodl account, something you wont touch for a few years. Use the other 10% to play with trading. Demo accounts are about as helpful as trying to play poker with fake money. Without the emotion or skin in the game, you play differently. Most importantly, don't rely on emotions to trade. Learn how to backtest and learn how to translate what you think the market will do into a testable method.
