Stocks and Forex

Polygon.io is a data provider for Stocks, Forex and Options. TAAPI.IO is a proud partner of Polygon and can vouch for their data quality. With this integration, our customers will be able to get all our technical analysis indicators on forex and US stocks in real time.

Query

Following the direction in the Direct Method, all you need to do is add a few parameters to your query:

Parameter	Type	Mandatory	Description
type	String	Yes	[forex, stocks, options] – This tells our API which asset class you’re looking for.
provider	String	Yes	polygon
providerSecret	String	Yes	Insert your Polygon API Key.
adjusted	String	No	[true,false] – defaults to true. By default, we show indicators or candles adjusted for splits. Set this to false if you want your data unadjusted.
interval	String	Yes	Interval or time frame: We support the following time frames: 1m, 5m, 15m, 30m, 1h, 2h, 4h, 12h, 1d, 1w. So if you’re interested in values on hourly candles, use interval=1h, for daily values use interval=1d, etc.

Note, some parameters are no longer needed:

• exchange: This is irrelevant as data comes in aggregated from Polygon, from multiple exchanges.

Bulk

Bulk queries will work as well, essentially making these calls very efficient, as you can calculate up to 20 indicators, off of the same candle set. If you have multiple constructs included in your plan, this will work efficiently too, as we’re calling each dataset asynchronously from Polygon.

Example

As a very simple example, please try this AAPL RSI query on the daily timeframe:

curl https://us-east.taapi.io/rsi?secret=MY_TAAPI_SECRET&type=stocks&provider=polygon&providerSecret=MY_POLYGON_SECRET&symbol=AAPL&interval=1d

Discover Symbols

type	String	No	Defaults to ‘crypto’. Other options include [stocks, forex].
