Final answer:
Setting stop-loss orders is a step in using trend lines for trading, while predicting interest rates is not. Identifying trends, analyzing market sentiment, and setting entry/exit points are the key steps. Additionally, a rise in the supply of money in the financial market usually leads to a decline in interest rates.
Step-by-step explanation:
When using trend lines and selecting a timeframe for trading, setting stop-loss orders is indeed one of the steps typically involved. However, predicting interest rates is not directly a part of this three-step process. The three main steps in trend analysis for trading purposes are usually identifying trends, analyzing market sentiment, and setting strategic entry and exit points, which can include setting stop-loss orders to manage risk.
Regarding the question on changes in the financial market that lead to a decline in interest rates, an increase in the supply of money, or a rise in supply, will typically lead to lower interest rates. Increased supply means more money is available for borrowing, which can reduce the cost of borrowing, reflected in lower interest rates.
