A calculation method of Slippage of optimize can never understand it.
Mysterious numerical value is calculated even if I break the difference of the profit and loss that I included profit and loss and Slippage which I do not include Slippage in in with the number of the buying and selling and is mystery how you calculate Slippage.

I am similar, and Slippage is written as a tick unit, but reason does not accord with the calculation result mentioned above either.
It is essential to know a calculation method of Slippage for a cost estimate.
Please please teach a calculation method of Slippage.
