Since you never really bothered to read what I wrote, I'll thank you for making some of my previous points and making a fool of yourself in red.

So why do you constantly criticize and contradict everything I say? I've given you plenty to look up on your own and verify. And they're not my standards. These are just the basics of the basics. You seem insistent on constantly leading people astray. If you really think you're so good, then I...

First: UltimateBootCD.com. Run some of the diagnostics on it like memtest, mprime, drive tests. The first 2 should be run for 24 hours minimum. I've had brand new hardware fail some of these. I run these periodically to make sure my existing hardware is still behaving. Second, Truly Wiping A...

@Zzzz1: You and what real world admin experience? Your C# example is hilarious. And I'll say again: I'm not talking about optimizing down to assembler. I'm talking about thinking ahead to use efficient code and designs from the start. A backtesting framework hosted on a limited server isn't...

Zzzz1: You're still thinking 100% in terms of workstation and not server. I can't help you anymore. There's an old saying that "Programmers make bad admins". It's true in many cases. I started out with difficulties but learned quickly. Your statement about worrying about optimization later is...

So you don't know. You're trying to present yourself like you have real world server experience when you don't. You deflect to other issues. I see this kind of answer all the time. Language makes a huge difference. I already noted that with python in a previous post. You seemed to agree. Let's...

@Zzzz1: Which language were you using? There is a massive difference between loading raw data off a disk and getting it from a database. Since you seem to know so much, why don't you take us through the internals of each process? ...all the way down to the kernel level... And we're talking...

Properly stored local data will be far faster than any DB. Local disk space is far cheaper than a database. I've been doing some personal programming for SierraChart that I've open sourced. Since you're likely to still have space constraints, I'd recommend converting to a smaller binary format...

@fan27, I'll give you a different point of view from the admin world and capacity planning. Since you're expanding your web site, execution efficiency and memory footprint become very relevant. If you have a program (or program module) that takes 30megs RAM to execute and a server with 8g RAM...

Forum Moderator: While this discussion is about technical indicators to forex, this discussion might want to be moved to the forex forum given the results I found below. I'll leave it to your discression. ---------- In further researching my above questions, I wasn't too thrilled with what I...

Tax shelters around the world could be shut down over night... by greedy governments lowering their own taxes to something reasonable and competitive. High taxation has nothing to do with capitalism. It has everything to do with control and socialism. I find the word spinning quite irritable.

If the NN was trained on mostly upward moving prices, it probably won't fully understand downward movement even if it is just "flipped". I've heard of some people using one NN for price increase and swapping to another for price decrease. I can't remember if it really outperformed a single NN...

I guess I should give a quick update... A few times a year I'll run Jstock with Yahoo as a more advanced volume screener to make an active stock list. I tried this yesterday and Yahoo's delayed service freaked out. It's sad when Google/YouTube can easily do 1g in a night, but Yahoo's delayed...

Occam just made me remember something I forgot... Looking at my package list in my xubuntu 14.04 install, I have gcc-4.8 and gcc-4.9 installed. Doing a package search on packages.ubuntu.com for "gcc base", it might be possible to "forward-port" the older package kinda like Occam was saying, but...

There are a couple of technical indicators in forex called Absolute Currency Strength (ACS) and Relative Currency Strength (RCS). I'm looking for information about how they are calculated. Wikipedia has an entry on each, but is vague. Deeper web searches don't turn up much. A few people have...
