Wookey, while I was away I thought of exactly this point that you made here. I'd like to add a rule, that if the first AO bar appeared when the ATR was over 0.08 we do not enter even if by the time the 2nd bar appears the ATR is back in normal range. The same applies if the first bar had a candle of 8 pips we don't enter this trade. These rule safeguards you from a quick move like you mentioned. In regards of prevention from slow moves, don't we already have the rule of below 0.02 ATR; are you suggesting here you have a new idea?
