Stock market prediction
Hi all, I'm new to this forum,
suppose that by telepathy it could be found if the price would be lowered or increased, so that a stability on some domain can be found,
what will the effect of a rat running on the keyboard ? It could not be predicted by telepathy, and could induce chaos

Hi jk22;
You are not that new, I know you. I have heard of Eddington's monkey but the rat on the keyboard is new to me.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

I am working on it
Still, I need to build probability knowledge, time series, wavelet analysis from scrach.
Quant is a tough job.
