CFD trading without a fundamental view – a recipe for disaster?

Been thinking a lot lately about how many folks jump into CFD trading purely on technicals, especially with something like $SPX500. Saw it touch 7444.32 today, impressive, but if you're just drawing lines on a chart without even a basic understanding of why it's moving – the macro picture, earnings, sentiment – are you really trading, or just gambling?

I mean, sure, price action is king to some extent, but without a fundamental anchor, especially on broader indices, it feels like you're missing half the story. The daily range from 7348.88 to 7444.32 today offers plenty of scalp opportunities, but for anything beyond that, it feels a bit thin. Change my mind, I'm genuinely open to hearing why a purely technical approach to CFDs on indices is sustainable long-term.
