Hi, Looking for some help with following situation.
Say we have 3 moving averages: MA_Short = MA(C,20) MA_Med = MA(C,100) MA_long = MA(C,200); My signals are the following Buy = MA_Med > MA_Long AND Cross(MA_Short, MA_Med); Sell = Cross(MA_Med, MA_Short); However, I only want to trade the first occurence of cross(MA_short,MA_Med). I don't want to take another long trade until MA_Med has dipped below MA_Long and risen above MA_Long again and the Cross(short, med) situation occurs again. I suspect it has something to do with the flip() function but I can't quite sus it out! I've nearly worked it out with a loop, but I'm sure that it's not the correct way to use AFL. Any help greatly appreciated! TIA Robert
