Review: The lower supports 1991.75, 1994.20 are the 0.5000 retracements for: 2116.48-1871.91 and 2116.48-1867.01 respectively. and the low was 1993.26.
The Fibonacci projections does not yield a single target, So I have tried my best to guess these possible outcome.
The bottom chart shows to you that a very simple Fibonacci play can keep you in-check for intraday fast-in-fast out play.
