The variable slippage option offered in portfolios has been slightly altered to better accommodate ETFs.
Stock variable slippage will remain the same, but ETFs will receive the following slippage factor:

Variable slippage for ETFs gives higher returns than 0.1% fixed. Looks like a more realistic formula.
