Yeah man, it would make you so much more solid. I am honestly surprised you haven't put some concentration in this area. The market is open 24/5 and trillions move through it daily, so buying and selling is nothing. GBP/USD seems to be one of the more volatile currencies. I was messing with Trix,ADX,MACD,SSO, and drawing trend lines, GBP/USD appeared to have lots of respect for them all. It also seems to respect both bol and fibs.
Here's something I pulled that I thought you might find interesting.
"Forex is a more predictable instrument than stocks. Forex prices have historically followed well-established trends. A forex trader need only to draw up a trading strategy based on a combination of fundamental and technical analysis to maximize profits. Stock markets, on the other hand, have historically suffered from "insider trading" scandals."
Here's the bigger chart on a 30 day scale. Made it so you could see it does seem to be a little predictable. Also if you decide to mess with it...TDA has a larger spread almost two more pips then Forex.com. I use there ForexTraderPro for trading and TOS for charting 4x.
