Will take awhile for liquidity to build, just look at volume candles on /ES contract, really not much during Asian trading session

24 hour trading is avail on brokers like IBK, webull, hood, etrade, Schwab (short lists of tickers, but useful ones, QQQ, SPY SMH etc). If you're looking at just ARca's order book, liquidity is pretty thin overnight before 4am EST
