Might check here Various mt5 indicators there is a mtf version.

4 Level ZZ Semaform mtf alerts This indicator, in the same position, will replace the low-level symbol after the high-level symbol appears: for example, when 2 appears, it will replace 1, when 3 appears, it will replace the old 2, and when 4 appears, it will replace 3.

No .mq5 version found.
If the teacher has time, I expect you to make a version of 4 Level ZZ Semaform mtf alerts.mq5.
