RE: [amibroker] Average: barssince, cum(1), sum ??

["Graham" <gkavanagh@xxxxxxxxxxxxx>]

You use the Cum function I 
think would be easiest
 
PPOover = 
PPO>0.15;  
PPOcount = 
cum(PPOover);  
PPOtotal = 
cum(PPO>0.15);  
PPOavg = PPOtotal / 
PPOcount ;  
 
Hoping I have understood 
your requirements.
