Sometimes it would be nice to have a way to gauge whether the current trend-following indicator is correct or not. For this, we will employ a trend-confirmation tool. Much like a trend-following tool, a trend-confirmation tool may or may not be intended to generate specific buy and sell signals. Instead, we are looking to see if the trend-following tool and the trend-confirmation tool agree.
In essence, if both the trend-following tool and the trend-confirmation tool are bullish, then a trader can more confidently consider taking a long trade in the currency pair in question. Likewise, if both are bearish, then the trader can focus on finding an opportunity to sell short the pair in question.
One of the most popular – and useful – trend confirmation tools is known as the moving average convergence divergence (MACD). This indicator first measures the difference between two exponentially smoothed moving averages. This difference is then smoothed and compared to a moving average of its own. When the current smoothed average is above its own moving average, then the histogram would be positive and an uptrend is confirmed. On the flip side, when the current smoothed average is below its moving average, then the histogram would be negative and a downtrend is confirmed.
