Ans. To read the Aroon lines, find the crossover between the two, the point where the up and the down line intersect. Depending on how they intersect, you can decipher them.   For example, if the up line moves above the down line from below, it means that there is a buying pressure. This leads to the development of a bullish trend as buyers become stronger than sellers. If the Aroon up line goes close to 100, the bullish trend is confirmed because the up line would reach 100 only when there is a new high.  If the up line remains between 70 and 100, the bullish trend would sustain. If the up line starts falling and crosses below the down line, the bull run would start losing momentum. The same concept, when applied to the down line, can signal bearish trends.
