Quote from mogul:
on that note, does randomness even exist? Or are events merely classified as random based on our level of perception.
A computer generating a random number is not random, but for all intents and purposes it can be used as such
There's a difference between "random" and "unpredictable." A truly random event cannot be predicted, even if the observer is able to accurately measure every causal action operating upon the potential future effect.
A merely chaotic event is potentially predictable, because it is the product of completely measurable causal factors.
At the most fundamental level, uncertaintly in the universe is still an open question. The majority of theoretical physicists subscribe to the "Copenhagen Interpretation" of uncertainty, which holds that it is indeed impossible to simultaneously meausre both the speed and location of an electron, and therefore true randomness exists in the universe.
The minority, however, believes that there are other mathematically plausable explanations (e.g., "many-worlds uncertainty interpretation") that would permit simultaneous measurement, and that we simply arent yet able to implement the math with any physical technology. If true, then all things are measurable, and randomness is merely the product of insufficient data.
The above represents the "naturalistic" explanations for randomness and uncertainty. There is, of course, the "supernatural" explanation, which would be basically, that God created the universe, and therefore randomness exists or doesn't exist, depending upon God's requirements at any given moment.
If you accept this last theory, then you don't need any technical or fundamental tools to make money in the market. You need only prayer.
