Greetings Ma,
Thanks for reading my article and finding it helpful. I'm glad I could explain Fibonacci retracement and how the percentage ratios are calculated in a clear way. It's great that the charts of the crypto pairs helped illustrate its usage during uptrends and downtrends. Those key levels are definitely important to watch, as crossing those ratios can signal a complete reversal of the trend, especially in higher time frames. I appreciate your kind words and good wishes for the contest. Best of luck to you too.
