An LLC can help; but in just a few ways.

It's best to use a pass-through entity like an LLC taxed as a partnership. That means all income and losses passes through to your individual tax return; where you pay taxes. No taxes are paid on the entity level, except some minimum (stealth) taxes due in most states.

So the character of the income and loss does not change. If it's IRC 988 ordinary gain or loss on the partnership return (LLC), it's the same on your individual return.

Single owned LLC's are "disregarded entities" and since you don't have a partner all the income and loss is reported directly on your individual tax return. There is no partner so you can't file a partnership tax return.

You need trader tax status to qualify for business treatment, even in an entity.

Entities are helpful tax wise is creating the opportunity for AGI deduction like retirement plans and health insurance premiums.
