It also allows you to search for trades by stock, instead of needing to parse through thousands of disclosure forms.
I do want to mention one weakness of my data, which is that I don't currently parse hand-filed disclosures. Most politicians do electronic filings, which are easy to scrape, but some still file by hand. Working on a solution for that, which should hopefully be live before too long.
What is the lag between the trade and the public disclosure ? My guess pretty long so probably fairly useless data.
[edit] The tweet's one example shows a month for that particular example "This came after purchases of up to $115K of $LMT by Representative Scott Franklin on September 12th, which were disclosed on October 11th."
So can't see how building a trading bot that trades on information at least a month old even if info at the time was good would give any big advantage. This strategy is going to be fairly useless imo over the long term even if you assume the politicians trading was better than the overall market.
If anyone is interested, I built a dashboard that tracks the performance of individual congressional stock trades here:
