Summary
The post describes an algo trader's experience deploying a mean-reversion strategy, highlighting an unexpected operational failure due to Windows power settings on a local machine.
The author's main thesis is that the physical hardware and operating environment are as critical to a trading system's success as the code and strategy logic itself.
Quality assessment: This is an anecdotal account of an operational issue, not investment research or due diligence. It contains details about a specific trading strategy but offers no performance data or backtests. It is primarily noise from an investment perspective.

I recently crossed the finish line on getting my mean reversion system to run completely on its own, and the biggest roadblock completely caught me by surprise. I spent all my time obsessing over the Python logic and the Alpaca API connection, only to realize that the physical hardware environment is just as critical as the strategy itself.
When designing the system, I purposefully avoided jumping on the AI bandwagon. I see a lot of people trying to use language models to execute trades, which seems incredibly dangerous. My risk management is entirely based on rigid math. The bot only trades equities so I never have to stress about options expiring worthless. It relies on a 50 day moving average to confirm the macro trend and looks for extreme oversold RSI levels. The real defense is a strict falling knife rule where the bot outright refuses to buy until the price actually bounces above the previous close. If a position goes against me, the system just waits patiently for the price to recover past my entry and the 5 day moving average before escaping safely.
The logic worked beautifully, but taking it live locally was a complete disaster. I tried using Windows Task Scheduler on my main laptop to trigger the daily scripts. It turns out that silent power saving modes and deep hibernation states will just completely ignore scheduled background tasks. The bot would sleep right through its execution windows, leaving me totally exposed. It was a very frustrating couple of days thinking my code was broken when the laptop was really just taking a nap.
I finally accepted that true autonomy requires a dedicated cloud server, and moving it over to AWS fixed everything overnight. I would love to hear what kind of stupid, non coding hurdles the rest of you ran into the first time you took a system fully live.
