On each time frame / fratal, at any given moment there is a dominant direction. The price moves in the dominant direction have higher amplitude that in the non dominant direction. When multiple time frames are dominant in the same direction, their effects add up, and the expectancy is higher.
The Yale students were not told that the food distribution was random..sorry kid. I think op is trolling. But the rat experiment assumes 2 things. 1.) That markets are random. 2.) That there is a bias The rats simple approach leads to optimal results only if food distribution(or the stock market) is random AND there is a bias. Neither of these things have been proven in the stock market, so the experiment proves nothing as it it relates to the markets.
You sure? Technically its pseudo-random. Assume I pick random numbers in some sort of way. Then every 25th number I choose a number my self. Its not random but there is no way to decided a pattern and guess my 25th number
Nobody else would know the number is not random. There is no way to observe a random biased selection..unless of course you have access to PRICE DRIVERS
Your assumption is you would have picked the profitable direction. And the problem with picking two directions is it increases potential unprofitable trades.
