Trend, swing, momentum trading, all generally mean the same thing. In theory, the idea is that you buy something underpriced/overpriced when your technical momentum indicators tell you that momentum is increasing/decreasing. Can be used in all time scales (daily, weekly, monthly)

I was really interested in finance, technical analysis (Alex Elder books), etc for a bit, but don't really have the capital to do anything, and is probably soothsayer type stuff anyway. Best real strategy is passive ETF vanguard type investments
