Thanks for the answer.
To be honest, i am feeling really dumb, since i didn't understand the
explanation.
Please suppose the following scenario:
Low[9]=950
Intermed[9]=970
High[9]=1000
auxCrossedIntermed=IIf(Low< Intermed AND High> Intermed,1,0);
CrossedIntermed=auxCrossedIntermed OR Ref(CrossedIntermed,-1);
On the bar #10, how will Amibroker evaluate the second formula?
During the evaluation, what will be the values for auxCrossedIntermed
and Ref(CrossedIntermed,-1) ?
Best Regards!
