What is Account sizes?

Account size is the nominal balance your simulated or funded account starts with. It sets how much a single trade is worth, and it usually rises with the price of the challenge that unlocks it.

Apex Trader Funding starts at 25,000 USD. Alpha Capital Group offers $5,000 to $200,000 simulated, and Bulenox runs $25,000 - $150,000. City Traders Imperium lists several ranges across its account types and scales to USD 2,500 - 100,000 (1-Step and 2-Step), USD 2,500 - 80,000 (Instant and Direct), scaling to USD 4,000,000, while Blue Guardian steps through 5K, 10K, 25K, 50K, 100K, 200K, 300K, 400K. Pick the smallest that suits the risk you can carry.
