TWS API - New Scan Filters
In the beta release of the TWS API there are now custom scan filters that you can apply. This functionality mirrors what is available in TWS so now it can all be done through the API. This should make filtering out junk way easier.
To get this you need to apply for the private GitHub repository by signing a form. Eventually this should make its way into the “latest” API version.
Some really important ones:
