What is Volume Climax And Range Climax? How to achive these

can Any body give me code for this in afl?

you will need to look for your own definition of climax.

a starter could be this:

Vclimax= V>2*MA(V,100);//
Buy = Vclimax;//

Which says basically:
If the V today exceeds 2 times the Moving Average of Volume of the past 100 days, it’s a climax.
