Would you say a 'hinge' is just a 'triangle pattern', though?
The hinge can be called a triangle or it can be called a coil, but what it's called is irrelevant. What is important is that wide disagreements among buyers and sellers as to the value of whatever it is become ever-narrower over time, which may last for minutes or weeks. This narrowing is accompanied by a decline in volume. Once price reaches equilibrium, it will then move either up or down. If the volume is conducive to an explosive move, there will be one. If interest dies, then you end up with a lateral range.
Is there a way of determining whether price will move up or down after it's reached equilibrium? Not by 100%. That's why the trader has to be prepared for both, as I tried to point out with regard to oil last February (the idea of preparing for both eventualities was met with great hilarity by The Elite).
