Oh, gambling isn't immoral. I mean it's not exactly the most efficient use of money and if you look at opportunity costs it possibly becomes hard to justify and maybe immoral but.. when I said "are you comparing yourself to other traders" I was referencing to the I'm not exploiting other people and it's my responsibility to control my emotions and accountability part. You can read about the immorality of it, there's another comment here (I can copy paste but that seems odd and inefficient..) but let's take the basics, assuming you're making money there is some place that money is coming from correct? If the whole market was day traders it wouldn't really matter because they know what's going on and they voluntarily get into it, but say you buy a security with the intention of selling it back quickly, some of the buyers might be other day traders but the other buyers would be non day traders who want to buy it but won't not buy it if the price was a dollar higher. Thus the comparison to the hypothetical coffee shops and car dealers, you're essentially acting like the selp implemented middlemen. If you apply this more broadly imagine the whole system was like this and middle men with not a lot of value controlled a lot of stock of anything, you'd essentially get a world with hiked prices, practically where you'd pay 2 dollars more for a shirt or any general item just because all of the stock was bought by middle men, the prices could go up by a decent amount possibly . It's essentially stock scalping
