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
