Insider trades

The Insider chip filters the feed to Form 4 activity — the open-market buys and sells by a company's own officers, directors, and large holders. These people know their business better than anyone, so what they do with their own money is worth watching.

Buys versus sells

Both directions show up, but they don't carry the same weight.

• Sells happen for all sorts of reasons — tax bills, diversifying, a scheduled plan, a new house. A single insider sale rarely tells you much on its own.
• Buys are different. An insider buying their own stock on the open market is spending real money on a bet that the price goes up. There's only one obvious reason to do that, which is why insider buying gets attention.

Clusters

The strongest version of the signal is a cluster: several insiders at the same company buying inside a short window. One executive buying might be personal conviction. A handful of them buying at once is much harder to dismiss, and it often lines up with a turn in the stock. SecBot flags these so you don't have to spot them by hand.

TIP

Filter to Insider, then push the Impact slider up. The cards that survive tend to be the meaningful buys and the clusters, not the routine scheduled sells.

You can also follow the most active insiders over time, which surfaces the names trading their own stock most aggressively right now.

The deeper signal work lives in two places: Insider Cluster shows the clustering signal on its own, and the Insider conviction tutorial walks through how to act on it.
