Fractals are a rough or fragmented geometric shape that can be subdivided into parts, each of which is (at least approximately) a reduced-size copy of the whole. Fractals are generally self-similar and independent of scale.
The highest and lowest points (Top and bottom)
This method is a simple way to determine support resistance, by looking at historical data where prices are stuck. For more details, you can just look at it from the picture.
Where you just see where prices are stuck. The greater the timeframe used, the more likely it will be the support and resistance.
It all boils down to practice, knowing current fractal patterns and having them engrained in your mind, and then you WAIT for the FRACTAL TRIGGERS, and REACT in real time, just as as you trade traditional price patterns such as double and triple tops as identified in real time. Fractal triggers are not limited to Bar charts.
The bottom line is this, that there is no black or white, no holy grail, everything has its basis in how we interpret the world around us is be it markets or the wider environment, fractals appear to offer the best window into a better interpretation of the world in our time, until the next innovation comes along.
