Forex trading system

Most Forex trading systems forget about the most important component in a trading system, price action. Incorporating it in our trading system will generate more consistent results.

Trading the Forex market has became very popular in the last few years. But how difficult is it to achieve success in the Forex trading arena? One of the main reasons of this is because Forex traders focus on technical indicators to make their trading decisions and totally forget about the most important factor: Price behavior.

Most Forex trading systems are made off technical indicators (a moving average (MA) crossover, overbought/oversold conditions in an oscillator, etc.) But what are technical indicators? They are just a series of data points plotted in a chart; these points are derived from a mathematical formula applied to the price of any given currency pair. In other words, it is a chart of price plotted in a different way that helps us see other aspects of price.

There is an important implication on this definition of technical indicators. The fact that the readings obtained from them are based on price action. Take for instance a long MA crossover signal, the price has gone up enough to make the short period MA crossover the long period MA generating a long signal. Most traders see it as “the MA crossover made the price go up,” but it happened the other way around, the MA crossover signal occurred because the price went up. Where I’m trying to get here is that at the end, price behavior dictates how an indicator will act, and this should be taken into consideration on any trading decision made.

Trading decisions based on technical indicators without taking price action into consideration will give us less accurate results. For example, again a long signal generated by a MA crossover as the market approaches an important resistance level. If the price suddenly starts to bounce back off that important level there is no point on taking this signal, price action is telling us the market doesn’t want to go up. Most of the time, under this circumstances, the market will continue to fall down, disregarding the MA crossover.
