V Shape and Inverted V day trading strategy

My day trading strategy is brutally simple. I hunt for "V" and "inverted V" patterns spot the move, drop the fib, aim for a 50% retrace, and strike. No fancy tricks, no wishful thinking.
I keep my risk-reward ratio at 1:1. I only risk 2% per trade, sometimes 1% if I'm feeling smart (which is every day, because blowing an account is for amateurs).
Trading is basically glorified gambling anyone who tells you otherwise is selling dreams. You can't control the market, but you damn sure can control your risk.
At the end of the day, it’s simple: Manage your risk or get managed out of the game. STAY TUNED!

Hi, can you kindly show from which levels you would draw the FIB? How do yuo know the top and bottom levels? And also, when you mean strike at 50%, how exactly do you determine a buy or a sell?
