In this article we present a version of the Vortex technical indicator developed for the Metatrader 4 trading platform, which can be downloaded and used at no cost. This indicator, although not as well known as other technical analysis tools such as MACD or RSI, can be a useful tool, especially if it is combined with other indicators. In fact, there are different trading systems that incorporate the Vortex and that we will describe later. For now, we will focus on providing a short introduction about this indicator and its trading signals and then we will talk specifically about the Vortex indicator for MT4 and its main features.
