Hi Graham,
It doesn't seem to work. When I put this in indicator builder, I only
get an avg value of 1?. As well, it is my understanding that the cum
(1) fuction calculates all the data since the start of chart,
whereas, I was hoping to set a condition regarding set # days.
PPO = (EMA(C,20)-EMA(C,50)) / EMA(C,7);
PPOover = PPO>0;
PPOcount = Cum(PPOover);
PPOtotal = Cum(PPO>0);
PPOavg = PPOtotal / PPOcount ;
Plot( PPOavg, "PPOavg",5,1);
