Hello and Welcome!
Dave answer was a bit confusing so ill try to clear it up:
Target zone is draw by the fibonnaci expansion tool in mt4, ewaves does it automatically yes (improved version of AO for lazy people). Buy it at steve's website if your interested
http://www.for-exe.com
Basically it points where the wave 5 will end more or less with good accuracy (80%+ dont recall the exact number)
We use it just to get an idea if theres enough room for your 2:1 R:R, and yes you use the 2:1 and sl to be at 1:1 for starters, dont worry much about target zone at first, you can draw the fibonaci and look at the target to see if theres enough room to move for your trade.(theres videos in the forum showing how to draw the fibo)
How we trade?
You look for waves 3 .. the big ones, the easy to spot ones.
Wait for the pullback (which is the wave 4), this can be a big pullback or small, or sideways range.
Look for signals there at the end so you can catch the wave 5.
Its this simple.
Every setup here is somewhat based on this, be it hunt signals, setup 1 or 2, etc...
The hunt method is all of those different entries applied to different time frames using the fractal geometry of the market, but all of it is based on the original setup. So dont complicate too much, if your starting just stick to setup 1, follow the flowchart, and make trading plan with t20 method of discipline training. The hunt and the rest will come to you easily once you master the setup, and it will all be very simple and easy to spot with a quick glance at a chart.
