Unable to fetch partial days

[ivnnv]

Hi, Im trying to fetch data from some timeranges that are not "full days" as all the examples shown, so something like this doesnt seems to work:

const { getHistoricalRates } = require("dukascopy-node");

(async () => {
  const historicalRates = await getHistoricalRates({
    instrument: "audusd",
    dates: {
      from: new Date("2019-06-09 08:24"), // it does work with just  "2019-06-09"
      to: new Date("2019-06-09 18:24"),   // it does work with just  "2019-06-10"
    },
    timeframe: "m1",
  });
  console.log(historicalRates);
})();

Link to runkit

Is this true? workaround seems to fetch the full days between the needed ranges but ideally this should be managed internally

@ivnnv 2019-06-09 (June 9th 2019) was Sunday which is not a trading day on forex markets. For that date, Dukascopy has data only after 2019-06-09 21:00 UTC.

This means that within range between 2019-06-09 08:24 and 2019-06-09 18:24 there is no data, that is why you are receiving an empty array.

However, when requesting data between 2019-06-09 and 2019-06-10, dukascopy-node will convert it to something likes this 2019-06-09 00:00 - 2019-06-10 00:00, and since the only available starting point for this date is 21:00 , it will fetch the data for a range of 2019-06-09 21:00 - 2019-06-10 00:00 - which is 3 hours, or 180 minute candles, which is exactly the output you're getting.

Hi, sorry I didnt checked the date was indeed, Sunday, it works exactly as expected on date range: 2019-06-07 11:24 2019-06-07 11:26 and returns as expected, only two records.

Thanks for checking and the detailed explanation tho. 👍🏽
