How do cards in a deck relate to the market? You know precisely how many cards are in a deck as well as precisely which ones there are but not their order. Whereas in the market you could say we have an infinite number of cards and we also don't know what they are. I think we are in agreement except for our terminology. I believe that the market will sometimes do what we expect but we never know for how long it will last, how often the event will happen, or when the next occurrence of "successful trade outcome" will take place. Purely random.
