Day trading tax as single member llc

Hi,

 

I have  setup SIngle member LLC (disrearded entity)  for my traing purpose.

I have couple of question.

1. Do i need to file quaterly taxes?

2. Am I supposed to pay sef-employment tax (Somewhere I read tradign business is not subjected to self-employment tax).

3. How do I report loss-and-gain from my trading?Sch C or Sch D

 

Not I have not elected M2M as I need to offset the losses incurred in the previous year when I was not LLC.

 

Appreciate your comments
