Studying Trends via Screeners

I pulled EXK from a FINVIZ screener setup as I attempt to search for potential swing-trade stocks. I'm still very new to this and trying to understand proper trending, support, resistance, etc. I THINK I see a pretty strong upward channel showing fair areas of support (horiz. blue) and moving a little sideways after a brief peek through a $6.02 resistance.

Screener settings:
- 20-Day Simple Moving Average = SMA20 above SMA50EXK
- 50-Day Simple Moving Average = Price above SMA50
- 200-Day Simple Moving Average = SMA200 below SMA50
- 20-Day High/Low = 5% or more below High
- 52-Week High/Low = 70% or more above Low
- Beta = Over 1
- Current Volume = Over 1M
