Congress Trades On Chart

A custom indicator created by TrendSpider Team on TrendSpider. You can import this custom indicator into your TrendSpider account. Don't have TrendSpider? Create an account first, then import the custom indicator.

This indicator will display markers on your chart indicating when US Congressmen make a trade. The data is pulled from public record filings required by law and is thus subject to delays. You can filter by party and type of transaction. The labels can be used in visual scripting. For example, this indicator enables you to scan for where a congressional buy signal has emerged.

Source code

This indicator had been implemented by TrendSpider Team in JavaScript on TrendSpider. Check out the developer documentation to learn more about JS on TrendSpider.
