Trading fees on a Spark funded account are unchanged from your Spark Evaluation: 0.04 bps per side plus a 0.013% daily swap fee on real-world assets (XYZ100, S&P500, and commodities). Crypto fees are unchanged at 4 bps per side (8 bps round trip).
Your funded account still runs on simulated capital, so these fees aren't charged to you directly, they reduce your account's demo balance, which determines your profit split and payout amount.
