You will find that the best way to get help on the forum is to show your work first.
If you have tried some code, and can explain what is not working the way you think it should, post it (USE CODE BLOCKS '</>'), and you will usually get much quicker support.
The other advice for newbies is to use the SEARCH. Alternatively, the HELP in the application, and the User Manual.
As a hint, search/look up Explorations.
Most of the helpful members here want to see you put an effort in, and then they are usually very helpful.
The reason everyone wants to see you try, is because realistically speaking you will not get very far in your journey if you do not learn to code yourself. Someone will write you this script, you will likely see that it can be improved, and wont know where to go from there.
When you do your search for Explorations, you wont find your exact question. But you will find enough to get your started in learning.
If you do not want to lean to code, there is an AFL code wizard that you might find useful.
The code within "Screener" is saying:
"Close today -minus- Close yesterday -divided by- Close yesterday -multiplied by- 100."
This has nothing to do with what you asked for.
You are also improperly using AddClumn (which isn't even necessary in order to perform your actual screen).
@TrendSurfer has given you your first criteria but he has used the variable "myPriceFilter" instead of "Screener". You can name it whatever you want.
Use that as an example to code the rest of your criteria for the volume's and MA.
@lscharkie Sometimes I think when the request is simple and at least some effort has been made, that it is easier for the forum users to post some example code.
You weren't specific about some of your filters but this could get you started
VolumeFilter = MA(Volume, 50) > 100000; // ave volume of the last 50 bars > 100,000 shares
MinPriceFilter = Close > 0.35; // you could Paramaterize this part for flexibility
MaxPriceFilter = Close < 10.00;
Turnover = Close * Volume > 1000000; // Dollar volume at least $1,000,000
TrendFilter = C > MA(C, 50) AND C > MA(C, 100) AND C > MA(C, 200);
AllFilters = VolumeFilter AND MinPriceFilter AND MaxPriceFilter AND Turnover AND TrendFilter;
