HARMONIA OS + FATBOOK™

See the Auction. Read the Flow. Trade the Framework.

Harmonia OS is an AI-driven auction-market framework designed to identify where price is most likely to move next—not by predicting, but by measuring balance, imbalance, acceptance, rejection, and probabilistic reach.

Rather than relying on lagging indicators or traditional support and resistance, Harmonia maps the live auction around key zones—including 20%, 50%, 80%, EQ, and EXT—creating a structured framework for market bias, targets, rotations, and trade opportunities.

FATBOOK™ takes Harmonia deeper, adding real-time order-flow and liquidity intelligence around those levels. Liquidity, delta, CVD, absorption, exhaustion, aggressor behavior, and developing order flow help reveal whether price is being defended, rejected, accepted, or preparing to break.

Together, they create one unified trading ecosystem:

HARMONIA OS → Map the auction.
FATBOOK → Read the flow.
FAT WICK → Execute the edge.

Built for ES, NQ, YM, and RTY, from discretionary Harmonia entry models to the framework powering Fat Wick automated strategies.

    Best algos on the market and they are constantly improving. Unlike other algo companies Seven is constantly making updates to adapt to current market conditions. You will not find better value for the price anywhere else.

    Seven is an incredibly active algo maker and trader. He’s constantly improving his algorithms, which are already very profitable. In an industry filled with scammers Seven is one of the few legit ones. I made back my membership within 24 hours of joining and running the algos, and months later I’m s...
