Fractal Corridors is a lagging channel connecting Fractal highs and lows each with added/substracted pre-set value.
It is inspired and designed for Vladimir Poltoratskiy's trading style with his ST patterns (book: Forex Strategy: ST Patterns Trading Manual).
However, to keep the charts clearer, I used William's Fractals that require two previous and following candles to be higher/lower opposed to just one as described in the book.
You may choose to disable fractals and view the channel only.
