How to read this

We take the highest and lowest price of the last 60 bars and cut the gap between them at the classic Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%), plus extensions beyond both ends.

“Tested N×” counts how many of those 60 bars actually traded through the level. A level price has crossed many times is one the market has repeatedly agreed on; a level at 0 is pure geometry the price has never reached.

This is a map of where trading has already happened — not a forecast and not a signal. Price moves through these levels all the time.
