These zones were created by combining several indicators, as well as Fibonacci and volume profiles.
I started by laying out 2-3 point spread rectangles on high volume nodes on the volume profile , and then refined those zones based on previous consolidations. I then added overnight/intraday ranges levels, highs and lows. I mapped out auto-fib retracement levels (as well as reversed auto-fib levels), and 1hr woody pivots on a 1hr timeframe. I switched to standard pivots and mapped those as well. With all of these levels marked, I looked for areas where they were grouped and further refined the rectangles. I also noted where the 34/50 ema cloud was in relation to the zones.
I'm currently a member of TradePro Academy, and these trading zones were mapped out using some of the theory provided in their futures course.
