Insiders already tell you what they think.
Most people never read the filing.
Every time an officer or director buys stock in their own company on the open market, U.S. securities law requires them to disclose it to the SEC within two business days, in public, for free, forever. ZycaAlgo exists because almost nobody actually reads those filings — there are roughly 1,500 of them on a typical day, and the signal is buried under noise.
What "noise" actually means here
Most Form 4 filings aren't a bet on the stock — they're routine. A director exercising options and immediately selling to cover taxes. A CEO's pre-scheduled 10b5-1 plan executing a purchase that was decided on months ago, before whatever is happening in the stock today. A 10%-owner fund rebalancing a position that has nothing to do with conviction.
None of that is a real signal. It's paperwork.
That's a narrow definition on purpose. Out of roughly 1,500 filings on a typical trading day, the ones that survive every filter usually number in the single digits. That collapse — from thousands down to a handful — is the entire point. It's also the part nobody does by hand at 7am before the market opens.
The actual filter, and why each piece exists
- Transaction code P only. Not A (awards), not M (option exercises), not S (sales), not G (gifts). Code P is specifically an open-market purchase — the insider paid cash for shares, the same way anyone else would.
- Officer or director, $100,000 minimum. Filters out token purchases that are more optics than conviction, and 10%-owner-only filers, who are usually funds rebalancing rather than individuals making a bet.
- Never a 10b5-1 plan trade. A pre-scheduled plan purchase was decided on months earlier, for unrelated reasons (often just diversification on a fixed schedule). It carries far less information than a trade made today, at will.
- S&P 500 or NASDAQ-listed, $1B+ market cap, 500K+ average volume. The research edge concentrates in small, illiquid names that are easy to find and hard to actually trade in size. Rather than pretend that's not true, we exclude them.
The full pipeline and a live example of what actually clears every filter on a given day are on the home page.
What happens after a signal qualifies
Qualifying buys get mirrored into a live Alpaca paper account — simulated money, real market prices — at 2% of account equity per position, capped at 15 open positions at once. Every entry carries a 15% stop-loss that begins trailing 10% below the high-water mark once the position is up 15%, and anything still flat after 90 days closes automatically. None of this is discretionary once a signal qualifies; the same rules apply every time.
Built in the open, on purpose
The entire pipeline — the SEC scanner, the liquidity filter, the position sizing, the exit logic — is public. Not a summary of it: the actual code that runs every weekday morning.
Why that matters more than a marketing claim
Most "insider trading signal" products are a black box: you're asked to trust a track record you can't verify and a methodology you're not shown. That's a reasonable thing to be skeptical of.
Here, the filtering rules, the exact SEC data source, and the trading logic are all inspectable on GitHub. You don't have to take a claim about the strategy on faith — you can read the eleven lines of code that decide whether a filing qualifies.
What this is not
This is not investment advice, and ZycaAlgo is not a registered investment adviser or broker-dealer. It's a mechanical filter applied to public filings, running against a simulated account. Simulated results don't reflect the slippage, liquidity constraints, or execution costs of real trading, and a filing pattern that worked in the past is not a promise about what happens next. Insiders buy for a lot of reasons, and being right about the company doesn't mean being right about the timing.
If you're evaluating whether to eventually connect a real account, that's a decision worth making slowly, with your own risk tolerance in mind — not because a landing page told you to.
