    Ray Dalio on Failure, Meaningful Work and Relationships

    I believe we're all in different phases at different times. So what may help an individual, can be toxic to someone else (misunderstanding). Then we need to seek out what works and judge it by how well we think it works for us. The best is if/when we successfully judge ourselves. It's a first...

    Hackers steal Bitcoins worth over $73 mln from NiceHash pool

    The technical issue is that no computer system is secure. Not a single usable machine. The more usability and utility, security trend towards worse and worse. So it comes down to: How gullible or downright stupid are non-technical people? The incentives for keeping secrets online are perverse...

    Hackers steal Bitcoins worth over $73 mln from NiceHash pool

    To the end user it really makes no difference. Relying on keeping secrets is a fundamentally flawed business model. Information tend to become freed.

    Hackers steal Bitcoins worth over $73 mln from NiceHash pool

    Better backup and retention policies, hopefully. Truth is though, no computer system are safe from breaches, so any secret keys can be obtain by resourceful adversaries. The more value, the more incentive to steal.

    What will subdue BTC and sustain it lower?

    Lack of fuel to burn: homes, food and medicine. A better alternative that is not an uncontrollable beast that may consume the planet. Honesty, integrity and empathy in proponents. Renewed interest in safety, robustness and self-preservation.

    What platform do you use to run multiple intraday strategies?

    Good writeup. Not sure sure what you consider a programmer, but sounds like you could program something from the start. Wether scripting shell scripts or writing huge java enterprise applications, you're still a programmer, and the latter can sometimes be a worse solution if a shell script is...

    Reverse engineering why indicators don't work

    If it merely resembles a plane, it's an idol. If it is able to lift off, it's a plane. Imitation doesn't have to be bad, but often the original creators, the people who went before you, had much deeper ideas than you yourself ever did. This is true in so many areas. So don't be in a hurry...

    Reverse engineering why indicators don't work

    The first calculation is same as bar.0 minus bar.28, divided by 28. Doesn't change your outcome, but faster to calculate.

    Reverse engineering why indicators don't work

    Whatever and however you trade, any directional trading will be dependent on trend. As trading anti-trend is like sailing against the wind, this is something you'd want to avoid naturally. Blame education and standard tests. These are poor preparations for business, and trading is a business...

    I would like to become an automated trader. How do I start?

    Would you be able to implement something in LibreOffice Calc? You may be able to use that to generate alerts. Formulas are declarative in form, so even though a bit limited in function, they are helpful for simple prototypes. Might provide you new ideas on how to go forward and you can extend...

    Microstructure question

    If this is all you've got, notice how the closes are rising for each bar. The long "wicks" below could be rejection. I'd call this slowly trending / grinding up. You might want to take upward accelerations as buy signals. The curves are maximum allowed bar-bar volatility/trade signals. Type of...

    Chronic stress skews decision toward high-risk/high-benefit

    But how rational are people behaving, or do they react by instinct ("feeling") more? There are studies on people who have lost emotions/feelings, they become incapable of decision-making and initiative-taking, so it seems "feeling" is more fundamental, so-called "rational" thought-processes not...
