Lose $5. Seems like a reasonable enough experiment.

$5 * 3 models per day=$15 a day Assume the experiment runs ~250 trading days in a year, consider the worst case they lose all their invested money=$3750. A little more than $5 :)

Good point.

That said, many hobbies cost more that $3750 per year, and that $3750 is a worst-case scenario. He might even make a profit, and hone skills that might make him a fortune.

What your suggestions is front running. This is illegal for stocks and most assets (not FX!). This will get a broker in hot water. The more nuanced practice that brokers use to monetize is payment for order flow. They sell your security order flow to algorithmic trading shops that buy and sell the securities you want to trade. You’re correct in that most retail orders never make it to a regulated exchange, but that m…

Right. They sell the order flow to the dark pool who then front runs the order. I haven't looked at this since like 2018 but last I checked the only major brokerage that didn't sell order flow was Interactive Brokers.

They still have to guarantee best execution.

That's of no predictive value for a day, a month, or even years.

BTW, with the birth rates dropping well below replacement, a decline in the population is inevitable, and property values will drop.

That's assuming you don't fill the gap with immigration.

My first email address it wouldn't accept.. wouldn't let me use it. Maybe the domain hit some censor (fscking.com) Did a different email, it accepted it, I got the email, but got this error message when trying to confirm it: {"error":"Invalid verification token"} and a pretty-print checkbox that did nothing.

Hey, can you try again? I ran into an API limit that should be resolved now

Yup, worked now. Signed up.

Do you know the difference between a limit order and a market order?

Yes, and it's irrelevant to my point.

Explain how you can get filled on a limit order and "get an adverse price"

May I ask what mail service you use? I’m looking for one for my next side project.

EDIT: disregard…I saw in another comment you mentioned you were using mailgun. Thanks.

The former is a belief. It always reflects the imagined realities of those investing--we assume that business reality catches up with them, and it mostly does but not always within a predictable time frame.

> The former is a belief It's based on the Law of Supply & Demand, which is always in play.

Always in play for goods and services, but this is a crypto currency – it's supply is mathematically limited, and it's value is fully market-dependent – determined only by players on the market.

> fees, latency, slippage Whenever I trade, I somehow always get an adverse price. I figure it's the "no fee" brokerage chiseling a bit off for themselves. I compensate by being a buy and hold hold hold investor, so paying very little in aggregate for that. What I don't understand is how day traders avoid being eaten alive by this.

"Free" transactions are free because they're not immediate. The broker buys the share themselves and sells it to you at markup... ie: there is still a transaction fee, you just have no idea what it is. Day traders use platforms that are optimized for speed and minimal fees, and that don't charge fees based on lot size.

There’s no markup, regulations dictate that you must get NBBO or better

Why it's worth paying attention in math class.

> Why it’s worth paying attention in math class. Math class does not teach practical knowledge such as personal finance or health. Citadel returns since 1990 is 38% annual returns before fees to outside investors. They have a 5:50 fee structure. There are hundreds of more firms, staying out of the public eye. https://www.barrons.com/articles/multistrategy-hedge-funds-p... Minimum investment $5M. Sorry but the middle…

It teaches you how to work in a quant shop
