One minute. The whole product.
From the heatmap to the footprint, gamma levels, the accuracy checks and the free trial. Turn the sound on.
Eight tools. One screen.
They all run side by side in one dashboard, on the live Bitcoin perpetual. Pick one to see how it reads.
Illustrations of how each tool reads. In the app they run on live market data.
Graded against the exchanges, minute by minute.
A heatmap is only worth something if the numbers under it are right. On 2 and 3 October 2026 we ran the engine on the live market and compared every figure with each exchange's own records. The same checks keep running inside the server.
One thing we won't oversell: absorption is a pattern, not a prediction. Half of the signals in the test held after 60 seconds. Read it as context.

Questions people ask first
What happens when the trial ends?
Live updates stop. The dashboard still opens, frozen on the market as it looked when you opened it. Once your account is extended it goes live again within a few seconds, without signing in again.
Can I use one account on two devices?
One at a time. Signing in on a new device signs the old one out automatically, and a second tab takes over from the first. That rule is part of why the price can stay this low.
Which markets does it cover?
The Binance BTCUSDT perpetual by default, and the Binance BTCUSD coin-margined perpetual. Trades, open interest, funding and liquidations also come in from Bybit, OKX, Binance spot and Coinbase, and the gamma levels come from Deribit options. No altcoins, no stocks.
Is it really live?
Yes. The data comes from the exchanges' public feeds: the order book every 100 ms and every trade as it prints. The typical delay from Binance to our server is 64 ms; your own internet adds a little on top.
How do I pay?
When your trial ends, the dashboard shows WhatsApp and email buttons with your account email filled in. Pay by UPI or bank transfer and your account is extended by 30 days, usually within a few hours.
Will it tell me what to trade?
No. Flowdeck shows market data and a few model-based levels, like gamma walls and absorption. It's a way to see what other traders are doing, not a signal service, and nothing here is financial advice.
