    For US stocks, may I assume a 0.1%=0.001=10bps cost in my backtest?

    The strategy is a daily one based on hitting the open and close.

    Lets say the stock price is $100 per share and I am trading $10000 shares. So I am trading $1M in dollar amount.

    May I use 10bps * $1M = $1000 as my transaction cost in backtest?

    For HK stocks, due to the exchange stamp duty, it's going to be at least 20bps that's what I heard - so that's a lot of costs... what do you think?
