As copper wiring is increasingly replaced by fiber and wireless, what fundamentals are bullish? Or is this a currency-related play?

Looks like an ideal father/son project! These DIY Raspberry Pi projects are a great distraction when it's raining outside and you're stuck in the house and have gotten bored with your GPS-guided laser drone prototype.

90% is unrealistic, even for a "good" system. In any case, you should congratulate yourself that you are performing backtests which are giving you accurate results and demonstrating that the indicators you are testing are largely worthless. Initially, this is a difficult conclusion to accept...

I finally found an RPi project idea that is both practical and more cost effective than buying a comparable commercial product. It's an internet bandwidth monitor that logs your speed every n hour(s) for periodic review. This project is documented in the link below and I have a couple mods in...

Well said. No noise means no airflow (unless it's water cooled). Here's a bit of related trivia for fun: When the original Jurassic Park movie was filmed they had a scene in a room with a bank of computers that controlled the devices in the park. But the fans in the computer cases were too...

Hat tip to you! The textbook formulas in the public domain are best used for learning and reference. Then take the initiative to roll your own. That's how you make money in this business.

It's VERY difficult to diagnose problems involving your ISP (Internet Service Provider) connection without a comprehensive set of network tools that most people don't have or know how to use. Of course, there are more targeted ways to correct specific problems (e.g., ipconfig to force DHCP to...

You're quite correct on the dv/iv relationship, I mistakenly switched the terms in my previous post. I suspect the LinRegression would be the better predictor where you have a strong lead/lag relationship. But I'm not convinced that a lead/lag relationship exists in most markets.

Periodically refreshing your internet router connection is advised by my ISP. Establishing a fresh network connection and giving the ISP an opportunity to push updates to your router is considered good practice. Like all of us, my router is on 24x7 and the only time I think of refreshing it is...

So then, you take the correlation coefficient computed over the series and "apply" it to the last price of the dependent variable to predict the independent variable for the next period? Isn't this roughly equivalent to a simple linear regression where the dependent variable is lagged by one...

New Pi 3 announced for sale today: https://www.raspberrypi.org/blog/raspberry-pi-3-on-sale/

Has anyone built anything using a linux-based Raspberry Pi? All the project ideas I've seen written up are not very practical. Most of the things people are building as a kit project can be purchased brand new for a comparable price (motion alerts, etc). I'd like to get some hands-on...

Most traders use some form of TA and most forms of TA are based on lagging indicators making this topic quite relevant to traders. Semantics and theory are the foundation for execution strategies, and are therefore very appropriate for discussion by people who want to understand the basis for...

There is a huge difference between lagging indicators and coin tosses. If you're putting money on the line, you should understand the rationale for your trading decisions. Otherwise you might be a victim of spurious correlation (e.g., trading based on moon cycles or some other nonsense that...

I can't think of any reason someone would solely trade ag futures with modest success for so long unless your system is based on seasonality in that market. Why else would you trade ags? You can find more liquidity and price volatility in so many other markets. If I'm correct, then the...

Does your handle Dr Atsum, indicate you hold a PhD? If so, which field?

I would say my points relate to solvency, not inconvenience. But I understand your POV. I didn't make any reference to order flow, but since you brought it up I will comment on it. I agree with you on the general case about order flow not being useful. The exception is when it enables...

Indicators based on long-term timeframes like 10-months and 20-months tend to smooth out all the noise and whipsaws that challenge most of us. The problem with taking trade signals from long-term indicators on monthly charts is 1) drawdowns are very tough to stomach, 2) profitability and cash...

I would say that correlation, even your modified formula with a displaced time series, falls into the category of statistical methods and not traditional TA indicators. While both are imperfect, I have much higher regard for statistical techniques.

Card games like blackjack are a purely random system (assuming the cards are properly shuffled) and follow a normal probability distribution upon which card counting relies. It becomes more difficult to maintain the count with more card decks, which then requires a mechanical device hidden in...
