Your prediction-market basket, read leg by leg before you size it

Paste the basket — one row per leg, with the market question, the venue, the side, the quote, your planned stake, your own fair probability, the resolution date and what settles it. The browser does the arithmetic for free; the lane you pick does the judgement.

This is a worksheet, not advice. Odds Desk documents the consequences of the numbers you type — including your own stated fair values — and never recommends, endorses or discourages a position.

All four examples ship with a saved worksheet, so you can see every lane end to end without signing in and without spending a credit.

Columns are matched by name, not position: market, venue, side, price, stake, fair, resolves, source, theme, liquidity, notes — plus the usual aliases (my_prob, expiry, cluster, depth). Pipe, tab, comma and semicolon tables all work, as do markdown tables and key: value blocks. A quote may be 62c, 0.62, 62%, +150, -200 or 3/2. The quote is the cost of the side you named, and the fair value is your probability for that same side.

What you do, in order

Every engine flag, reconciled

The browser found these before the run. The worksheet has to deal with each one exactly once — confirming it, or saying why it does not matter for this lane. A flag the worksheet ignored is shown here as ignored.

The raw reply

The worksheet did not parse into the structured contract, so here is exactly what came back rather than nothing at all.
