Trading by hand

Everything below uses your Manual desk trading account, which appears in the console like any agent account.

Terminal

https://t5market.com/explore is the market terminal. The ticker strip on top shows every market's last session: the volume-weighted landed cost of what was executed, its change against the session before, the units bought and the session clock.

The big chart has one candle per closed session. Cost candles open at the first executed deal of the session (in listing order) and close at the last, with the session's lowest and highest executed landed cost as wicks; the dashed line is the lowest cost that was listed, the purple line the VWAP. Margin shows the same candles as margin to list price. Demand index is a line: the units sold in the session by every position that still had stock, divided by the quoted velocity those positions carried — 1.0 means the market sold exactly what was quoted. Desk P&L and Rates show the realised results of settled sessions. Under the chart the volume pane shows units bought at each close (bars, coloured by the candle) and units sold in the session (line).

Two naive overlays can be switched on: a 20-session moving average, and a trend fit with projection — a straight line fitted by least squares through the last N sessions on screen (N is yours to set) and extended over the next 8 sessions in the shaded area. The line is drawn in front of you when you change the window, and the note under the chart states its slope, R² and the projected values. Nothing but the points on screen enters it.

On the right, the book shows the open session's menu as depth by landed cost (deals listed at or below each cost level, and the desk's bids per level) and time & sales lists the executions of the last close. Hover for values, click a session to open its full menu with results. The page reloads after each session close.

Market boards

https://t5market.com/markets/m15 (and m45, h2, h10) lists the current session's menu — typically several hundred to over a thousand deals — with a session snapshot (lowest and mean landed cost, list price, desk bids) and the book. Filters: item family, minimum margin, minimum velocity, desk picks only; sort by margin × velocity, margin, velocity, unit cost, family or key; 50–500 rows per page. The menu is also available as CSV (menu CSV) and JSON.

Each row shows the deal (bundle title and contents), landed unit cost, margin to list price, quoted sales velocity, the maximum volume, and whether the desk's own policy bids on it. Set a volume and press ＋ cart, or press analyse.

Deal analyser

The analyser is a naive projection, built in two steps you can watch:

1. Observed. For every closed session of the window it plots what deals of that family actually sold — units sold per session per deal that still had stock — against the quoted velocity. Then it fits a straight line by least squares (or a plain average) through exactly those points and extends it over the 8 settlement sessions, floored at zero. Move the fit window slider or switch the method and the line is refitted and redrawn in front of you; the note states slope, R² and the projected values.
2. Projected P&L by volume. The cash arithmetic of a position — revenue at list price on min(projected sales, stock), holding cost per unit per session, the fulfilment fee, the write-off of unsold units — applied to that path for every volume. The band around it scales the path by the spread of individual deals' realised velocity (p10 / p90 against the median). Grey dots are what similar executed deals actually made, re-priced at this deal's cost; red dots hit a downside event.

Drag the volume slider: cash out, projected P&L and ROI, low/high case and the on-record share of similar deals that ended in profit update live. Click the curve to jump the slider. Add N to cart adds that volume.

What the projection ignores is stated on the page: downside events and their surcharge are not modelled (their observed share is shown instead), and demand beyond the stock that was on hand was never observed, so the history is made of sales, not demand.

Asset browser

https://t5market.com/assets lists every item family with current-menu numbers (deals, cost range, margin, desk bids) and recorded history (deals executed, desk mean per deal, account holders' P&L, profitable share, downside rate). A family page is a terminal for that family — cost candles of its executions, realised velocity against the quoted one with the same trend overlay, the family's book — followed by the analyser for the typical listed deal and the family's current deals.

Sessions

Clicking a session in the terminal opens its full menu with results: which deals were executed, sales session by session, units sold against the volume bought, whether the deal sold out, the realised result and whether a downside event hit.

Carts

https://t5market.com/cart shows your own cart and, below it, one cart per connected agent, each with a per-line volume slider, the proposer and its note. Lines are tied to the session they were picked in; when it closes they go stale and Refresh re-maps them to the closest deal of the same family on the new menu. One checkout at the bottom funds every current line of every cart (card or balance) and places the orders; Pay only this cart opens a cart's own checkout link. Lines you picked are ordered on your Manual desk, lines an agent proposed on that agent's trading account. Orders fill when their market's session closes.

Proposals from your agents

An agent proposes into its cart over the API. Until it is connected to your login it hands you the cart's checkout link (/carts/…); opening it — after registering or logging in on the page, or right away when you are logged in — connects the agent and shows its cart here from then on. Every agent of yours can see every cart of yours over the API; whether it may write to them or execute them is up to you:

Automation (full auto mode)

The Automation panel on the cart page lists your grants and adds new ones: an agent (or every connected agent), a cart (or every cart, including future ones), the level — write (add, re-size, remove lines) or execute (place and fund the orders at will) — and, for execute, whether it pays with a stored card you pick or from the account balance. Revoke a grant and the agent's next attempt is refused.

CSV orders

Upload a CSV with market, offer_key, qty rows (keys come from the menu CSV or the API), or market, family, qty, max_unit_cost rows to pick the cheapest current deal of a family automatically. A template is linked on the cart page; problems are reported per line.
