It is simple to trade with no indicator. This morning I got up 7:00 eastern time USA and noticed eur/usd was going down. So I sold at 1.2295. I don't know if it would go down farther, no indicator will tell you that. This is speculation, and no one knows where the market will head. Anyway, eur/usd is now around 1.2240.
So basicly, the way I trade is when the market is going down, sell. When the market is going up, buy. Then move stop to breakeven if market moves 20-25 pips in my favor.
Patience is needed and to avoid overtrading also.
