Do I use “Other Gains” for trading profits from my LLC?

I have a S-corp LLC that does daily trading for its main business with a leased office and everything. The 1099 is out and I have a question about it.. I get my payroll(W2) from this company.

1. When it comes to tax filing will the realized gains go under “Other Gains” in accounting? Obviously it will not be sales as it is not a “merchandise”.

2. In LLC, are long term and short term all taxed the same as a big chunk of “realized gains” together?

Thank you captains!!
