"Trader in Securities"-whats my IRS NAISC code?

[Htrader]

I will be filing as a "Trader in Securities" for the first time this year and as a result I can use the Schedule C to deduct expenses.

But on Schedule C you need to enter a code describing your professional business activity. There isn't an exact description for a Trader, the best I could find was #523900 - "Other financial investment activity."

Anyone know what number I should use? Or should I just use #999999, which is the "unclassified" option.

My tax accountant puts #523900 for me.

My accountant used #523900 on Schedule C.
He specializes in traders, tax prep.
