People, Whales who fat finger are not a common thing. What is worth worrying about is institutional algorithms. What do algorithms trade off of? Fibonacci levels. What makes the most use of fib levels? Elliot Waves. Thats where you should be investing your time researching.

You seem to have little understanding about whales behaviour. Not a fat finger! If you have the option to manipulate vast segments of a market into triggering understandably tight stop losses (in an iffy time of market such as this), and thus make the market collapse for an instant and simultaneously have buy orders in place for lower price, than that's a win for the whale, and a loss to all the fools with the tight stop losses/stopped out margin positions.
It's about knowing your place at the table. In those instances, you're shown... The earlier you understand this the better for you...
