Fees, price impact, and risk

How to think about trade costs and market risk.

Fees, price impact, and risk

Every trade should be judged by more than the headline price.

Fees and premiums

Buy and sell trades can include a premium or fee. Higher tiers can reduce trade premium through tier benefits.

Price impact

Price impact grows when a trade is large relative to the market's virtual depth. A small trade may barely move price. A large trade can move it more.

Risk checklist

Before trading, ask:

  • Do I understand the market question?
  • Is the market still open and before cutoff?
  • Do I accept the price and price impact?
  • Can I afford to lose these Credits?

Do not spend Credits you cannot afford to lose.
