<h2>Read this part first</h2>
<p class="dim">Four caveats, up here rather than in a footnote. If any one of them matters to your use case, nothing else on this page will help.</p>
<div class="facts">
<div class="fact">
<h3>The snapshots are top-of-book</h3>
<p>Best bid, best ask, and that is the whole of it. There are <code>level</code> and <code>size</code> columns, but they exist to keep the schema stable across tables, and every row has them at 0. A reconstructed ladder is a different table — and it does not reach all the way back.</p>
</div>
<div class="fact">
<h3>Depth starts 20 July 2026</h3>
<p>Fifteen days of the thirty-five have it. Everything before is quotes, trades and spot candles: still fine for flow and spread work, useless if you came to model the book. That gap is exactly why those days bill at 55% of a full one.</p>
</div>
<div class="fact">
<h3>The clock changes partway through</h3>
<p>Up to 20 July the timestamp is <code>ts</code> — our receipt time, rounded to the second. Ordering inside a second is gone and cannot be recovered. If your model cares about sequence at that resolution, buy from 21 July on, where <code>ts_ms</code> is exchange time in milliseconds.</p>
</div>
<div class="fact">
<h3>Uptime is measured, not claimed</h3>
<p>It runs from 95.8% to 100%, depending on the day. Each day carries its own figure rather than an average across the archive; the calendar shows it, and the price is computed from it.</p>
</div>

<div class="eyebrow">Pricing</div>
<h2>Pick a range, pay by the day</h2>
<p class="dim">Every purchase covers all four assets, and whatever streams existed on the dates you pick. Longer ranges are cheaper per day.</p>
<div class="scroll">
<table class="rates">
<thead><tr><th>Range</th><th>Rate</th><th>Example</th></tr></thead>

<tr><td>30+ days</td><td>$3 / day</td><td class="num">30 days, $90</td></tr>
</tbody>
</table>
</div>
<p class="dim" style="font-size:13px;margin-top:14px">Two rules keep the arithmetic honest. Days holding no data are not counted at all, so a range that straddles a gap costs less than its calendar length suggests. And a longer range never costs less than a shorter one — which is why the total flattens at $90 anywhere between 23 and 30 days.</p>

<h2>Getting the files</h2>
<p>Payment goes through Plisio, in crypto. Once it confirms you get a download list good for thirty days, with a request budget sized to your order. The bytes come straight from storage and never pass through our server.</p>
<p>A month is several hundred files. Clicking through them by hand is nobody's idea of a good evening, so the order page hands over the whole list as one text file, with a ready-made command under it for Linux, macOS and PowerShell.</p>
<p>If the data disagrees with what this page says, you get your money back. That is the whole reason the caveats sit at the top and not down here in the small print.</p>

<strong>On performance.</strong> The strategy this code implements was net negative over the author's own measured sample: about −$277 across 4 280 paper trades, −$371 across 4 722 in the live configuration, at a 47% hit rate against a break-even near 49%. No real order has ever been placed by the author — the execution path is written and exercised against the API, but every one of those trades was simulated. And since no models ship with it, a fresh install has no view of its own at all until you train one, which needs a fortnight of collected data before the gates will allow it. This is sold as working infrastructure, not as a profitable strategy. If you want a bot that makes money out of the box, do not buy this.
</div>
</div>
<div class="facts" style="margin-top:22px">
<div class="fact">
<h3>Configured from Telegram</h3>
<p>Position size, how many trades at once, the daily loss cap, the entry price ceiling — all set from chat, applied to the running bot, no restart. The live edition takes your wallet the same way: a guided prompt that deletes the message with the key in it and stores the key encrypted.</p>
</div>
<div class="fact">
<h3>You bring the models</h3>
<p><code>artifacts/</code> arrives empty. Gate A will not let you train on less than two weeks of collected data, and until there is a model the bot runs, reports and holds. Buying a month of recorded history from the <a href="#pricing">datasets</a> is the only way to shorten that wait. A first Gate B verdict of <code>FAIL</code> is the ordinary outcome, not a defect.</p>
</div>
<div class="fact">
<h3>You need a server and disk</h3>
<p>Two cores and 4 GB of RAM are enough, but recording the full book is 25–40 GB a day. The docs cover keeping a window instead, or trimming what you record — and training is hours of CPU you should not run on the box that is collecting.</p>
</div>
<div class="fact">
<h3>What arrives</h3>
<p>A tarball with the source, an idempotent <code>install.sh</code>, systemd units, the database schema in one file, and documentation written for someone who has not seen the code before. A manifest carries a sha256 for every file in it.</p>
</div>
<div class="fact">
<h3>Licence and support</h3>
<p>One buyer, any number of your own machines, source included and yours to modify. No redistribution and no running it as a service for other people. Support covers installation and defects — not strategy design.</p>
