Forex & Crypto

Forex

Read this section to know everything you need to know about using the various Forex HTTP endpoints.

See Async Support for REST endpoints for asynchronous use cases.

Docs below assume you have already read getting started page and know how to create the client. If you do not know how to create the client, first see General guide for clients & functions and create client as below. As always you can have all 5 different clients together.

import polygon

forex_client = polygon.ForexClient('KEY')  # for usual sync client
async_forex_client = polygon.ForexClient('KEY', True)  # for an async client

Note that most endpoints require you to specify the currency pairs as separate symbols (a from_symbol and a to_symbol).

however a few endpoints require you to supply them as one combined symbol. An example would be the get_aggregates_bars method. In those methods, the symbol is expected to have a prefix C: before the currency symbol names. but the library allows you to specify the symbol with or without the prefix. See the relevant method’s docs for more information on what the parameters expect.

here is how the client initializer looks like:

polygon.forex.forex_api.ForexClient(api_key: str, use_async: bool = False, connect_timeout: int = 10, read_timeout: int = 10, pool_timeout: int = 10, max_connections: int | None = None, max_keepalive: int | None = None, write_timeout: int = 10)

Initiates a Client to be used to access all REST Forex endpoints.

Parameters:

api_key – Your API Key. Visit your dashboard to get yours.
use_async – Set it to True to get async client. Defaults to usual non-async client.
connect_timeout – The connection timeout in seconds. Defaults to 10. basically the number of seconds to wait for a connection to be established. Raises a ConnectTimeout if unable to connect within specified time limit.
read_timeout – The read timeout in seconds. Defaults to 10. basically the number of seconds to wait for date to be received. Raises a ReadTimeout if unable to connect within the specified time limit.
pool_timeout – The pool timeout in seconds. Defaults to 10. Basically the number of seconds to wait while trying to get a connection from connection pool. Do NOT change if you’re unsure of what it implies
max_connections – Max number of connections in the pool. Defaults to NO LIMITS. Do NOT change if you’re unsure of application
max_keepalive – max number of allowable keep alive connections in the pool. Defaults to no limit. Do NOT change if you’re unsure of the applications.
write_timeout – The write timeout in seconds. Defaults to 10. basically the number of seconds to wait for data to be written/posted. Raises a WriteTimeout if unable to connect within the specified time limit.

Endpoints

To use any of the below method, simply call it on the client you created above. so if you named your client client, you’d call the methods as client.get_historic_forex_ticks and so on. Async methods will need to be awaited, see Async Support for REST endpoints.

The library added a better aggregate function if you’re looking to get data for large time frames at minute/hour granularity.

(for example 15 years historical data , 1 minute candles)

See Bulk Aggregate Bars (Full Range) for complete details on how to use it well and control how it behaves.

SyncForexClient.get_aggregate_bars(symbol: str, from_date, to_date, multiplier: int = 1, timespan='day', adjusted: bool = True, sort='asc', limit: int = 5000, full_range: bool = False, run_parallel: bool = True, max_concurrent_workers: int = 10, info: bool = True, warnings: bool = True, high_volatility: bool = False, raw_response: bool = False)

full_range – Default False. If set to True, it will get the ENTIRE range you specify and merge all the responses and return ONE single list with all data in it. You can control its behavior with the next few arguments.
run_parallel – Only considered if full_range=True. If set to true (default True), it will run an internal ThreadPool to get the responses. This is fine to do if you are not running your own ThreadPool. If you have many tickers to get aggs for, it’s better to either use the async version of it OR set this to False and spawn threads for each ticker yourself.
max_concurrent_workers – Only considered if run_parallel=True. Defaults to your cpu cores * 5. controls how many worker threads to use in internal ThreadPool
info – Set to False to disable printing mild warnings / informational messages if any when fetching the aggs. E.g. if there was no data in a response but the response had an OK status
warnings – Set to False to disable printing warnings if any when fetching the aggs. Defaults to True.
high_volatility – Specifies whether the symbol/security in question is highly volatile which just means having a very high number of trades or being traded for a high duration (e.g. SPY, Bitcoin) If set to True, the lib will use a smaller chunk of time to ensure we don’t miss any data due to 50k candle limit. Defaults to False.
raw_response – whether to return the Response Object. Useful for when you need to say check the status code or inspect the headers. Defaults to False which returns the json decoded dictionary. Will be ignored if full_range=True

Returns:

A JSON decoded Dictionary by default. Make raw_response=True to get underlying response object. If full_range=True, will return a single list with all the candles in it.

Crypto

Read this section to know everything you need to know about using the various Crypto HTTP endpoints.

See Async Support for REST endpoints for asynchronous use cases.

Docs below assume you have already read getting started page and know how to create the client. If you do not know how to create the client, first see General guide for clients & functions and create client as below. As always you can have all 5 different clients together.

import polygon

crypto_client = polygon.CryptoClient('KEY')  # for usual sync client
async_crypto_client = polygon.CryptoClient('KEY', True)  # for an async client

Note that most endpoints require you to specify the currency pairs as separate symbols (a from_symbol and a to_symbol).

however a few endpoints require you to supply them as one combined symbol. An example would be the get_aggregates_bars method. In those methods, the symbol is expected to have a prefix X: before the currency symbol names. but the library allows you to specify the symbol with or without the prefix. See the relevant method’s docs for more information on what the parameters expect.

here is how the client initializer looks like:

polygon.crypto.crypto_api.CryptoClient(api_key: str, use_async: bool = False, connect_timeout: int = 10, read_timeout: int = 10, pool_timeout: int = 10, max_connections: int | None = None, max_keepalive: int | None = None, write_timeout: int = 10)

Initiates a Client to be used to access all REST crypto endpoints.

Parameters:

api_key – Your API Key. Visit your dashboard to get yours.
use_async – Set it to True to get async client. Defaults to usual non-async client.
connect_timeout – The connection timeout in seconds. Defaults to 10. basically the number of seconds to wait for a connection to be established. Raises a ConnectTimeout if unable to connect within specified time limit.
read_timeout – The read timeout in seconds. Defaults to 10. basically the number of seconds to wait for date to be received. Raises a ReadTimeout if unable to connect within the specified time limit.
pool_timeout – The pool timeout in seconds. Defaults to 10. Basically the number of seconds to wait while trying to get a connection from connection pool. Do NOT change if you’re unsure of what it implies
max_connections – Max number of connections in the pool. Defaults to NO LIMITS. Do NOT change if you’re unsure of application
max_keepalive – max number of allowable keep alive connections in the pool. Defaults to no limit. Do NOT change if you’re unsure of the applications.
write_timeout – The write timeout in seconds. Defaults to 10. basically the number of seconds to wait for data to be written/posted. Raises a WriteTimeout if unable to connect within the specified time limit.

Endpoints

To use any of the below method, simply call it on the client you created above. so if you named your client client, you’d call the methods as client.get_historic_trades and so on. Async methods will need to be awaited, see Async Support for REST endpoints.

max_concurrent_workers – Only considered if run_parallel=True. Defaults to your cpu cores * 5. controls how many worker threads to use in internal ThreadPool
info – Set to False to disable printing mild warnings / informational messages if any when fetching the aggs. E.g. if there was no data in a response but the response had an OK status
warnings – Set to False to disable printing warnings if any when fetching the aggs. Defaults to True.
high_volatility – Specifies whether the symbol/security in question is highly volatile which just means having a very high number of trades or being traded for a high duration (e.g. SPY, Bitcoin) If set to True, the lib will use a smaller chunk of time to ensure we don’t miss any data due to 50k candle limit. Defaults to False.
raw_response – whether to return the Response Object. Useful for when you need to say check the status code or inspect the headers. Defaults to False which returns the json decoded dictionary. Will be ignored if full_range=True

Returns:

A JSON decoded Dictionary by default. Make raw_response=True to get underlying response object. If full_range=True, will return a single list with all the candles in it.
