I think it was you that said...if u get slipped by 20 ticks, the good thing is that there is usually 20 more ticks to go
Will make it harder to backtest around this issue. Will have to go back and get dates of when main news was released and then prevent entry and change buy/sell stops to limit orders after news has been released.
The two big events that stand out in my mind are the weekly inventory reports, and the monthly unemployment report (usually the first Friday of the month). You might want to consider stop limit orders.
