Actually, they have algorithms that monitor trading activity. They look for unusual buys from new accounts that were not trading, or unusually large sudden interest, just before big news. Insider information has a very particular look. They can spot it pretty well, I understand. Because most traders have a hard time understanding it or believing it, when it happens to them, they usually can't believe it and think someone told on them. Nope, it's more likely they spotted your trade in an otherwise not as complex picture as you might imagine.

I think it's harder to spot odd trading with MM's or institutional trading entities, as they trade a lot, and have so many trades, that small spikes in particular areas,are not necessarily so obvious. But a random doctor suddenly buying say 10,000 shares or something, out of the blue, just immediately prior to news. They are definitely going to investigate that situation, and likely, 9 times out of 10, your average person's response is going to be a dead giveaway when they ask.
