I don't think HackerNews supports enough Markdown to show tables but... tell me what you think about that.

I could be wrong because of the obvious downside of "if you get it wrong it'll expire 100% worthless by end of day" but if you can use "technical analysis" to know when to enter a long/short position, I'd say don't use margin (short) and don't buy the underlying (long), instead buy a slightly out of the money (this is where predicting which direction the market will go and for how much/how long gets... impossible) call or put depending on direction can yield a better return.

Obviously it's all gambling but I see why so many people are attracted (addicted?) to it (Robinhood traders)

If you lose 100% of a $100 out-of-the-money bet 7 times but then hit an 800% ROI... you break even, right?
