For me to predict whether the GBP/EUR is going to be either a uptrend or a downtrend, I use the EMA indicator to help me decide whether it a uptrend or a downtrend. I use the 200EMA to predict if the long term trend of the pair is going to be a downtrend or uptrend. If I wanted to know the short term trend then I would I would use either 10,20 or 50 EMA to help me decide what the short term trend will be. By using the 200EMA I Have managed to predict that the GBP/EUR is going to be a long term downtrend. The reason why it a long term downtrend is because the 200EMA is above the price so that shows the trend is in a downtrend.
