Price is not the outcome
A course should teach a process the learner can repeat without the instructor. Ask for a syllabus, prerequisites, sample lesson, worked exercises, assessment standard and refund terms. A list of profitable trades is not a curriculum.
Budget the hidden work
Enter the hours you can realistically spend, not the video's runtime. Practice, journaling and reviewing failed attempts usually consume more time than watching lessons. A high per-hour figure can still be justified by substantial feedback; a low figure can still be poor value if there is no useful practice.
Check against a free baseline
Before paying, try to complete one strategy definition using public material: entry rule, invalidation, position size, execution costs and out-of-sample test. Buy only if the course fills a specific gap you can name. Do not purchase on an implied earnings promise; education has no guaranteed trading return.
