The most important factor determining the direction of a parity is the news about the currency concerned and the perceptions of the Market Players about that parity.
The issue is that if the USD raises the interest rate on the EUR / USD parity, the USD-oriented transaction can be opened without any technical analysis required.
News and economic data can be traced from various Forex sites.
In addition to this, Market Players may decide that if a parity is going to go up, the Buy operation can be started regardless of the technique. Perceptions of parities can be controlled with data called Sentiment.
Perhaps the most important technical issue in Forex is the determination of support and resistance points.
Resistance of a previous support when drawing Support-Resistance should not be taken for granted that a previous resistance might support.
After setting the graph to detect DDs, at least 2 points that are paused at the same level are determined and a horizontal line is drawn. The price is more likely to pause and change direction at this level.
Note the support and resistance in the picture. The price is having difficulty passing through that region.
Trend lines also affect parities like the same support resistance. Trend lines generally work with 3’s. This is called the sister technique.
When plotting the trend line, the previous 2 dips or crests are determined. The price is expected to return from these lines.
If the trend line is exceeded, resistance can be turned into support.
