如何在 TDAmeritrade API 中获取 EUR/USD 等外汇价格历史？

Question

I use the TD Ameritrade API as documented on the API documentation .

The URL to get the price history contains the symbol of the asset to fetch.

The documentation says:

Replace the {symbol} in the URL with the actual symbol

It works well with stock symbols like GOOG or AAPL or FB.

For example for AAPL, the url would be: https://api.tdameritrade.com/vi/marketdata/AAPL/pricehistory

But with symbols that contain a backslash like the EUR/USD spot, it does not work because the backslash is considered as an additional path to the URL So I get URL not found withhttps://api.tdameritrade.com/vi/marketdata/EUR/USD/pricehistory

Same with EUR/CAD , EUR/GBP , and other forex spots. How to fetch forex spot?

Answer 1

Use a dot instead of the slash between the currencies. So this will work:https://api.tdameritrade.com/v1/marketdata/EUR.USD/pricehistory

Yeah, the docs are rubbish about it and even the symbol lookup returns the slash as part of the symbol eg. GBP/USD as a valid symbol:

{
  "GBP/USD": {
    "symbol": "GBP/USD",
    "description": "GBPound/US Dollar Spot",
    "exchange": "GFT",
    "assetType": "FOREX"
  }
}

Answer 2

for other broker (X Trade Brokers) you can request EURUSD price history in NodeJS https://github.com/peterszombati/xapi-node#get-eurusd-m1-price-history

request price history with this module is simple like this code

x.onReady(() => {
    x.getPriceHistory({
        symbol:'EURUSD',
        period: PERIOD_FIELD.PERIOD_M1
    }).then(({candles, digits}) => {
        console.log(candles.length);
        console.log(candles[0]);
        console.log('digits = ' + digits);
    })
});

Answer 3

Only Stocks , Options and Index prices are available from the pricehistory endpoint. I received an email from one of TD Ameritrades product managers confirming as much:

Hello Tobiah,

Thank you for the email and I apologize for the delay in response.

Forex data is only available via the Get Quote endpoint . Here is an example of a request for multiple forex symbols at once for an in the moment snapshot quote: https://api.tdameritrade.com/v1/marketdata/quotes?apikey=YING4&symbol=EUR%2FUSD%2CUSD%2FJPY

Get Price History is only available for stocks, options, and Index currently. Futures and Forex instruments would not be available through that endpoint.
