Hello @silencewan,
Thank you for participating in the 8th Week Crypto Course in its 4th season and for your efforts to complete the suggested tasks, you deserve a Total|7.5/10 rating, according to the following scale:

My review :
A good article in which you were able to answer most of the questions ably, and you have some notes that I made.

• A detailed explanation of the ROC indicator and how to calculate its value. It was possible to use a graph so that the result and your conclusion is closer to reality.

Thus, there is a common setting for this indicator which is the 9-periods but also, there are other commonly used settings that include the 14 and 25 periods as well.

• The most used periods correspond to ROCs at 12 and 25 for short and medium term trading. The ROC 12 is an excellent indicator of overbought / oversold in the short and medium term. The higher the ROC, the more the currency is overbought, the lower the ROC, the more likely a rally seems.

• As for the third question, in its second half, you did not go into depth in determining how to reverse the trend using the indicator.

• In the last question it was possible to extract several other signals.

Thanks again for your effort, and we look forward to reading your next work.
Sincerely,@kouba01
