I am convinced retail algo trading is just gambling with extra steps. Prove me wrong.

Summary
Author argues retail algorithmic trading is structurally disadvantaged versus institutional players, citing low long-term profitability rates, insurmountable latency and cost disadvantages, and rapid alpha decay.
The post is a skeptical challenge to the retail algo trading community, questioning if any genuine long-term edge exists for non-professionals.
Quality assessment: Well-argued speculation based on known structural market realities and academic studies. Not original research, but a valid synthesis of common criticisms.

I want to believe retail algos work, but the math says otherwise. From the outside, it looks like 99% (Comprehensive studies tracking day traders over extended periods (such as a massive, multi-year study of the Taiwanese market) found that only about 1% to 3% of active retail traders were predictably and consistently profitable after accounting for fees. ) of retail traders are just heavily overfitting historical data and writing Python scripts to lose their money systematically.
If you aren't a quant firm with co-location, alternative data feeds, and billions in capital, what is your actual edge?
A)The Speed Myth: You cannot beat institutions on latency.
B) The Friction Trap: How do you survive the constant bleed of slippage, bid-ask spreads, and fees without taking on stupid amounts of leverage?
C) Alpha Decay: Even if you find a tiny inefficiency, how does it not decay before a retail trader can actually scale it?
I don’t want your code, your secret sauce, or a 3-month P&L screenshot from a bull run. I want the structural logic.
If you’ve actually survived 8+ years and consistently beaten a basic S&P 500 index fund, how? Are any retail traders actually doing this long-term, or is it all just an illusion?
Change my mind.
