Questions about ConstantSlippageModel

I'm looking to model my commissions and had some questions about the constantslippagemodel.

Suppose I bought and sold 10 units.

The slippage would occur on both sides of this trade, correct?

So suppose I have a slipage model set to 0.0001m, this would be 1 pip, and so if I had this on a forex algorithm, it would be 2 pips in commisisons (buy, and sell) that would add to the spread, so a 4 pip spread would become 6 pips in commissions, right?

The ConstantSlippageModel represents a slippage model that uses a constant percentage of slip.
If we want a constant value of slip, we need to implement it. Here is an example from the docs:

// Assigning securities custom slippage models:
Securities["SPY"].SlippageModel = new CustomSlippageModel()

// Custom slippage implementation
public class CustomSlippageModel : ISlippageModel {
public decimal GetSlippageApproximation(Security asset, Order order) {
return 0.1m;
}
}

The calculated slippage will be added to the fill price.
Yes, you are right. It would become 6 pips.
