  I was wondering what everybody does to account for slippage?  When I'm looking at a backtest, I export the trades to Excel and then recalculate the gain/losses to account for trade costs (usually about $20).  But, I also started thinking about accounting for slippage by increasing the trade costs to something like $50 or $100.  Also, another idea was to subtact a percentage from every trade.  Thoughts?

  I don't focus on distractions.
 
 When I am in a trade only ONE THING MATTERS - PRICE!

  Well, I'm talking in reference to backtesting a filter.  Taking into account slippage and trade costs...

 I agree with you that slippage is important and should be taken into account. I also export my data to excel. I created a cell for costs. I entered $10. My trade result formula is ((SellPrice - BuyPrice) - Costs)). You can change the amount in the cell to see how an increase/decrease will affect the bottom line.
