Quote from Arjun1:
BTW Kris Kringle = Santa Clause for those that didn't know (I had to look it up).
100 heads in a row MUST HAPPEN as a function of PURE RANDOMNESS if you flip a coin enough times.
And when you have a billion brokerage accounts worldwide, 10k to 100 million events MUST HAPPEN out of PURE RANDOMNESS.
Most people intuitively (but wrongly) assume that these rare events disprove randomness when in fact they prove randomness.
However, good luck is a function of good design to a limited extent and that's all the hope you have as a trader.
This is not a good example...you are talking about billions of heads and tails flips, and nobody has time for that because in the long run we're all dead.
