Trading divergence is just a great way to spot trends and their reversals as you go by your oscillators and comparing them to your graph.
The real art of trading divergence is to spot it on time. For that we need to look for the different performance in the graph and in the oscillators.
Let’s look at the picture here. We see that the graph is hitting lower lows, but the oscillator is hitting higher low. And right after the lowest point in the graph we can expect a price to shoot up. That means that it is a perfect time to BUY and get profit off those pips you are bound to have.
