I have an automated trend-following system that day-trades futures profitably on a 5-minute time frame with 2 round trades per day on average. Since my brokerage (TradeStation) has Roth accounts only for equities (without the extra cost of using an intermediary company), I'm wondering if I can be as profitable applying the same system to the futures' ETF equivalents (like SPY for ES and QQQ for NQ). The PnL should be almost identical in terms of percentage because the buy/sell signals timing will be almost identical since the price movements will be almost identical for the future-ETF pairs. But my question is about dollar PnL.
I know two advantages of futures are leverage and tax. The tax advantage won't apply since this is a Roth account and gains won't be taxed. As for leverage, if I am only using a low 2:1 or 3:1 leverage in my futures trading, which can also be replicated in ETF trading, can we say that the leverage advantage also won't apply and thus conclude that there won't be any notable difference in my dollar PnL across ETFs and futures?
Edit: ETF trading will be cost-free but futures have a $4 round trade cost. Let's ignore that for simplicity.
