In element the operate accepts the following parameters

   int          timeframe,        // timeframe

   int          mode,             // line index

• Symbol is the instrument, utilizing Symbol() will use the present one

• timeframe is the timeframe of the chart, Zero will imply the present chart

• mode is to outline if searching for a fractal UP or DOWN, in reality the attainable values may be MODE_UPPER  or MODE_LOWER

• shift is the shift expressed in variety of candles

As is the fractal indicator may result difficult to use nonetheless I attempted to make a easy operate that you could use to detect Fractals.

The following code can retrieve three values:

1. The worth of the most up-to-date higher fractal
