Looking for Advice & Guidance

Turning 19 soon and I’ve been trying to build healthy habits with my money early on. I’ve started using Revolut and Moomoo to get exposure to investing, and I’ve committed about 20–30% of my monthly income to long-term investments instead of short-term scalping or paper trading. Thought I’d put this out here to get some guidance from those who’ve been investing longer.

1. I’m trying to figure out what platforms or resources I should be reading or learning from to deepen my understanding of investing. There’s a lot online, so I’m hoping to narrow it down.

2. Indicators-wise, I’ve tried paper trading using Bollinger Bands, Stochastic RSI, MACD, Volume, and Turnovers. I’m not sure if I should be diving deeper into more indicators, or if these are enough. I’ve also heard that some people skip indicators entirely and focus more on price action. Would appreciate thoughts on this.

3. For starting points, I’ve only invested in Silver (before the recent run-up) and Bitcoin (which just dropped today). I’m thinking of expanding into ETFs and stocks like the S&P500 or VOO, but they’re currently at all-time highs, so I’m unsure if now is the right time to enter.

Open to any advice - trying to build this properly from the start.
