I am considering switching to esignal. Can the following be done to create an automatic screener/scanner based upon my criteria? For example, say I want to automate something like the following:
1. Download last 30 days data for each stock in the SP500.
2. Calculate 20 day Bollinger Bands
3. Determine if current close is below the 20 day Bollinger Band.
4. If yes put this stock in a list for for further analysis.
This is something like a scanner, but it needs to be completely configurable to screen a group of stocks based upon user defined criteria such as bollinger Bands, Moving Averages, etc. Most scanners only scan based upon fairly simple predefined criteria.
Using the scripting language and a list of the SP500 securities, could I iteratively (or simultaneously), download the data and then run a script that performs the above or similar analysis, and spit out the list of stocks that meets the criteria? This would need to be able to be automated. I could sit there and do it myself one stock at a time, but the goal is to be able to walk away and return later to find a list of stocks that meets my criteria. I am comfortable programming in different programming languages. Thanks. I am not familiar with ESignal, but am considering it if it allows me to screen large numbers of stocks for my own criteria.
