These zones are calculated using Fibonacci Ratios of past price moves.
Fib extensions and retracements are projected forward in time and price.
If price bounces or reverses, it will probably do so at one of these zones.
Some zones will match previous highs and lows, since Fibs are derived from the extremes.
Some zones will not match anything previous, but they are Fib multiples and THOSE are the important ones.
Zones that are far from current price will be either WIDE or just a LINE. Just a line indicates important Fib Ratio.
Where prices overlap on the zone lines, drag the Right (price) Axis up to magnify and reduce overlap vertically.
There are zones above and below the current price range, Drag the Chart up/down to see other zones.
Drag bottom axis to the left to magnify the candle size to view close up, or to the right to view larger time frame.
I will update as new zones are defined by upcoming Fibs.
