Quote from the1:
I recently had a client with a very similar situation. He was a dentist who testified as an expert witness for additional income. He decided to pursue a Law Degree but the deduction was disallowed because it wasn't related to his primary business.
Since you have trader status and you're taking classes that pertain to trading they are probably deductible. If I have time I will try to find primary support for this deduction a little later. My weekend is packed so maybe on monday.
