Forex Trading

This morning, my trade finally went into the profit area. I closed the position taking a $100.00 profit. The problem I have with my profit is that I was afriad of losing the profit again. If I kept the position, I would have. However, I placed another buy again as I was afriad it would shoot to the moon as I went to work.  When I did arrive at work, it drop as low as 1.5733. I placed a stop at 1.5700. If I was stopped out of my position, I would have lost $500.00. Not good as I’m trying to earn a living here.
