Real Times News Will Not Increase Your Bankroll

Another explanation as to why real time news is useless:

Mike Bloomberg became the richest man in New York by selling traders just fifteen seconds head start on the data they needed. Fifteen seconds costs thousands of dollars a month per trader. But in most cases, what we get online is not actually in real-time and it’s not news, either.

Getting ever closer to the first moment is expensive in other ways. It might cost you in boredom, because watching an entire event just to see the good parts takes time, particularly if there’s no guarantee that there will even be good parts.

It might cost you in filtering, because the less you’re willing to wait, the more likely it is that you’ll see news that’s incorrect, out of context or not nearly as valuable as it appears.

When journalists, analysts and pundits are all racing to bring you the ‘news’ first, you get less actual news and more reflexive noise. Go watch an hour of cable news from a year ago… what were they yelling about that we actually care about today? (more…)

Trading and alpine climbing

“To climb mountains is to make decisions…. Good decisions are contextual, based on actual circumstances, and cannot be reduced to a set of rules…. In fact rules, guidelines, and codes, although useful for introducing concepts, ultimately become counterproductive when it comes to actually making choices… The simplest climb involves circumstances far too complex to be adequately addressed by rules. The mountain environment itself forces you to rely on your own skills of observation, your understanding of what you observe, and an accurate assessment of risks and of your own abilities.”

The authors continue: “Rules must be replaced by that mysterious quality called judgment. The acquisition of judgment begins with a mountaineer’s very first climb and continues throughout the climber’s entire career. It is a process that cannot be bypassed nor ever be considered complete.”

Principles that help guide decision making are:

Anticipate changes. “Continually look forward. Every change in terrain, route difficulty, or hazard may require a new strategy, mode of movement, or protective system to deal with new circumstances.” (p. 15)

Keep options open. “Any given decision can either maximize or limit other possible options in the future.”

Analyze benefits and costs. “Addressing one risk or solving one problem often entails introducing other risks or aggravating other problems.”

Maintain momentum. “Staying focused on forward movement means always being a little bit stressed, but in such a potentially dangerous environment, some level of stress is, arguably, appropriate.”

Gather information. “Preparing ahead of time will give you a head start…. Above all, remember what you see. Every glimpse is a new piece of the puzzle.”

Recognize and correct errors. “Rather than expecting perfection, strive to recognize errors as early as possible, and take steps to correct the situation. Do not carry on blindly, hoping that everything will work out. Denial causes delay, piling error upon error until only good luck can prevent things from spiraling out of control.” (p. 16)

Assess your own skill and knowledge. “An honest and dispassionate self-critique is indispensable. For example, the capacity to observe, predict, and respond to cues improves over time, just as movement skills and climbing ability improve with practice; but on the other hand, competence can be degraded temporarily by states such as fear or fatigue or by inadequate information and inaccurate perception.” (p. 17)

Alpine climbers take on considerably more risk than traders. After all, traders lose only money; climbers can lose their lives. But the way to the top demands similar decision-making processes.
