# Prices, charts & candles

Every number in Magpie comes from **MagpieOracle** — the same pricing engine we sell as an API (Magpie is its first client, SlabX the second).

## What you see on a card

* **Fair value (EUR)** — led by *realized sales* (including public on-chain sales of graded cards) when they exist; market aggregates and language- aware EU listings fill the gaps at a discount.
* **The band** (`low..high`) and a **confidence tag** (high/medium/low): a thin market says so. "We don't know yet" is a possible, honest answer.
* **Graded values**: gem headline + per-(grader, grade) breakdown — a PSA 10 and a CGC 9.5 are different assets.

## Charts

* **Line view**: the daily fair-value history with 30/90-day deltas.
* **Candles view**: finance-style OHLC with **1H / 4H / 1D / 1W** timeframes. Candle volume = realized sales in the bucket. Intraday candles densify as the oracle samples hourly; daily/weekly render from the full accrued history. No synthetic candles: gaps are gaps.

## Alerts & intelligence (Pro)

* **Price alerts**: "tell me when this drops below €X / rises above €Y".
* **Grading ROI**: expected uplift of grading a raw card vs the gem market.
* **Arbitrage views**: EU↔US and raw↔graded gaps — where the same card is cheap.

## Why trust these numbers?

The oracle publishes its own **accuracy** (walk-forward error vs subsequent real sales) and anchors its daily history on Solana mainnet — verifiable by anyone, forever. Details in the [MagpieOracle docs](https://oracledocs.magpie.gg).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.magpie.gg/the-app/prices.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
