Quote from NickelScalper:
The tide moves about a constant level.
Not so with market prices.
The tide is not constant. Every High tide is different from it's last and every Low tide is different from it's last and every High Tide is proportionally different from the last sequential Low tide and every Low tide is proportionally different from it's last High tide. But the tide's trend is determined by plotting the high tide and low tide levels making higher highs & higher lows or lower highs and lower lows.
Wow, that sounds really familiar . . . where have I heard that before.
Market prices mirror this action due to being born out of the same type of random chaotic environment as anything else effected by the Laws of Physics.
