New here, curious about scaling vs. single-point entries on $SPX

Hey everyone, been lurking a bit and finally decided to post. I'm relatively new to active trading, mostly focusing on $SPX options. I've been trying to refine my entries and exits, and one thing I keep wrestling with is the idea of scaling into positions versus taking a single, higher-conviction entry point. I see the benefit of scaling to potentially lower average cost or leg into a trend, but sometimes it feels like I'm just prolonging a losing trade or diluting the impact of a strong conviction play. For those of you with more experience, how do you generally decide between these two approaches, especially on something as volatile as $SPX?
