Many forex traders struggle to understand how and why the currency markets behave in the way they do, but in fact, it is not hard to understand once you start to think of it in terms of one where the flow is constantly from level to level and back again, rising, falling and then rising once more. This is why we always say it is a market of mean reversion where levels and flow are key. Levels dictate reversal points or pause points, whilst flow is dedicated by sentiment and whether it is universal across the complex.
