The future increase or decrease in the price of security is based upon what? Buying or selling pressure. This pressure comes from human's believing the price has his a threshold and is either too low or too high (either by directing clicking a mouse or creating an automated system). It seems like sometimes we as traders forget this. If we believe in a setup and KNOW if will go in our favor, the only way it will in fact do so is for other traders to have the same views. Other traders have to bid the price up, the stock will not simply increase because of the setup. This idea makes me question trading systems and ideologies. Why try to fight human behavior by creating an assortment of technical indicators that somehow "predict" price direction? If other traders never find that same correlation, how will the price go anywhere? I feel like price and volume are the only pure ways to gauge human behavior. Instead of attempting to find or create a secret or edge, maybe the simplest approach is the best. The two goals are to find out the bias of the market (long or short), as well as the strength of that bias. We as traders attempt to "ride" or maybe even anticipate the actions of crowds. The crowds (whether it be individuals or institutions) move the market, move the price. If we are able to go long before the last trader goes long, and exit before the exiting traders outweigh the entering traders, we make a profit. Obviously this is an oversimplified view of the market, but its a reminder on price action. Having the perfect setup can be a complete failure if it is not seen by other traders.
