FX:SPX500 S&P 500 index of US listed shares
Patterns form on these charts. We often see them as unique or non repetitive. However, the patterns repeat. Often replicating years old patterns in smaller time frames or much shorter duration of time.
I have marked with Fibonacci Time zones special points.
The boxes with color represent the same move. Basically, it is a replica.
Interesting to note is a flash crash in November 25th 2014 I attach proper gold chart.
