Your own free stock screenerhow to have oneThere are lots of questions about how to find free stock screeners in my mailbox every year.
Most screeners are available from stock exchange data services providers. I can hardly say that they’re best stock screeners, and you have to pay for them!
I’m happy to say that I discovered the way you can prepare your preferred stock screener on your own computer. It means you won’t have to pay a monthly fee for using such screener.
Steps to create a stock market screenerI recommend that you create a stock screener using a combination of AmiBroker software and Yahoo free stock market data. This combination can be fully automated so you can have a pre-selection of stock produced by the screener after a few mouse clicks.
You have to go through these steps:
1. Use AmiBroker stock analysis software
This stock analysis software has a lot of functions. One of them is you can create free stock screeners. You can make a lot of different stock screeners too. And in time you will find and use your preferred stock screener.

3. Define your stock screener rules
You can define your preferred stock screener as you go. There’s a huge selection of possible parameters that can be included in the stock screener definition. This check list can help you to prepare your list of necessary conditions for your stock screener.
4. Write rules of screener into formula file
You can easily use AFL Editor in AmiBroker to write all conditions for scanning into the file.

7. See results, move them to the Watchlist and do further analysis
During the run of the screener you will see a list of selected stock symbols grow. When your preferred stock screener finishes, you can copy all results to the Watchlist and go through these tickers individually.
