liquidity and slippage rules
ETFs trade all day. index funds only at the close. that makes ETFs risky for large orders. slippage can hurt your profits. use limit orders on ETFs. index funds have zero slippage but no control over entry time. for US traders, FTMO allows ETF trading, which is smart. Apex is better for futures, not ETFs.
tracking error and its impact
ETFs can drift from the index. index funds track closer. tracking error adds uncertainty. check it before trading. for a prop account, a 0.5% tracking error can break your drawdown. I prefer low-cost ETFs like VOO. Topstep also allows ETFs but has strict rules. stick with FTMO for smoother experience.
position sizing for day trading
day trading ETFs requires smaller sizes. use the 1% rule per trade. index funds are for swing trades. adjust based on volatility. here are key tips: - use limit orders for ETF entries. - set stop-loss at 1% of account. - avoid ETFs with low volume. - check tracking error weekly. - only trade ETFs on prop firms that accept US clients like FTMO.
stop-loss and expiry rules
ETFs support stop orders. index funds do not. for index funds, set mental stops or use a broker that alerts. prop firms like FundedNext only allow forex, not ETFs. so skip them. E8 Markets has ETFs but limited liquidity. for strict stop-loss rules, FTMO is the best for US traders.
regulatory and tax rules
US SEC regulates ETFs and index funds. wash sale rules apply to both. prop firms have different rules. The5ers allows index funds? check their terms. True Forex Funds does not. my advice: use FTMO for ETFs. they are solid with US traders. Apex is great for futures but not index funds.
