just wanted to add this : different brokers will show different prices especially on Flash Crash days
that October 2016 Cable Flash Crash in particular , ranges from 1.1904 to 1.1400 and even lower on some other borkers
your chart and your Fib projections are good , just be aware that on other Platforms the low that day was about 1.1900 , so different tests should be made with different prices
