This is not a trade idea as no strong trend but an example to new traders of how to use MACD divergence. In the circles you can see the price makes lower lows as does the histogram. When the histogram makes significant humps like that you should expect another move in that direction after price goes back to the zero line. In the third circle you can see price makes a lower low and the histogram is much smaller. When this occurs you should not take any more trades. In the final two circles you can see a higher high in price and histogram, therefore I would expect another move up until there is a smaller histogram. In this example I would look to the 50% line and previous resistance as well as round number support at 6.5500 to enter long and look for a run up to Previous high and round number resistance @ 6.7000. Don't do this though as there in not a strong enough uptrend to make this trade worthwhile.
