slippage

When your running your simulations, how much would then bee a normal
trading slippage ? I have a volume over 100.000 (dayli) and over 5
dollar on the stock is then slippage on 0,5 % (inn and out of a stock)
on marked order, and 0,1 % on limit order. Is this correct ? ore to
much ?

Are you buying at the ask and selling at the bid with market orders?

What is a normal bid/ask spread for this particular stock?
