are markets truly random?

Some say yes, others say no.

So it depends who you ask. Physicists say no, practitioners say yes.

I say it's random enough to not make a killing off of for an extended period of time.

Ask George Soros then ask a Phd. mathematician making 30k a year.

The markets are not random, but traders are.

 

[Indrionas]

They're random in a way that they're not 100% predictable.

There are many threads from the past asking such questions. Perhaps you should use the search feature of this forum.

A few notes on your generator:
1) you use excel's RAND() function, which generates values of uniform distribution.

2) therefore you get daily ranges from 0 to 1 which are uniformly distributed, i.e. chance of any range is equal to any other range between 0 and 1.

3) in reality, distribution of market's daily ranges are similiar to normal distribution with fat-tails
