After reading through the documentation and experimenting, it's not clear to me if it is possible to write a slightly nuanced crossover alert. I am using three averages and would like to be alerted when the shortest length has crossed BOTH the medium and long term averages. This often occurs within the space of 10-20 bars but rarely happens on the same bar. Is there logic available that would provide for a lookback period with regard to evaluating such a crossover? Appreciate your advise on this issue.

ID1 = short ID2 = med ID3 = long =OR(AND((ID1.SG1>ID2.SG1),CROSSFROMBELOW(ID1.SG1,ID3.SG1)),AND((ID1.SG1<ID2.SG1),CROSSFROMABOVE(ID1.SG1,ID3.SG1))) what this does is when uptrending waits for short to be below med then alerts when it crosses below long.. reverse when downtrending. if theres any other conditions i missed just tell me |

Trade2day1, Thanks very much for the clever logic. During basing patterns or areas of consolidation, the short will sometimes cross the long first and afterwards cross the medium. However, I can follow your template and add both those as additional conditions within the overall OR statement. SC Engineering, Could you please comment if there is a method / function / alternative solution that would provide for a lookback constraint when evaluating conditions. I think this could open up a lot of possibilities across a broad range of studies. Appreciate everyones help on this thread. |

http://www.sierrachart.com/index.php?l=doc/doc_AlertCondAndScan.html#ReferencingDataOtherLastBar << that is the look back function i thought about that too about the long first then medium, but if you used the same logic i did then in up trends when the short crosses below the med then back above it you would get alerts every time.. couldnt figure that one out |

Is there logic available that would provide for a lookback period with regard to evaluating such a crossover? No. In the case of when using the CROSSOVER function, it works with specific data.
