AlphaVantage¶

Already have an AlphaVantage API key? Add it to Lavender Terminal and your option chain and ticker header fill with live AlphaVantage market data, right alongside Lavender's independently computed Greeks.

What you get¶

AlphaVantage provides option and equity market data over a REST API. Connected to Lavender, it drives:

Options — bid, ask, and sizes per contract
Stocks — the latest price with the day's open, high, and low

Lavender requests the latest equity quote with AlphaVantage's realtime entitlement. The Greeks and implied volatility you see in the Montage are always computed by Lavender's own engine, independent of the data feed.

Connect it¶

In Settings → Data Feed, select AlphaVantage and enter your API key.
Restart for the change to take effect.

Your key stays local

Your AlphaVantage key is stored on your machine and is used only to request data directly from AlphaVantage on your behalf — it is never sent to Lavender.

How data arrives¶

AlphaVantage serves snapshot data over REST. Lavender polls it on a clock and refreshes the chain and ticker each cycle. You set the cadence per data type in Settings with the Reload secs field.

Match the reload to your plan

A shorter reload means fresher data and more API calls. Choose a reload interval that keeps your polling within your AlphaVantage plan's rate limit.

Data types¶

Choose which AlphaVantage data Terminal pulls: options and stocks, each with its own reload interval. Tick a type to enable it and set its reload; at least one type stays selected.
