I'm trying to convert milliseconds timestamp to a DateTime, but it throws an exception at reader.GetString():

System.InvalidOperationException: 'Cannot get the value of a token type 'Number' as a string.'

It means I'm trying to read it as a string when it is a value. If I replace it with reader.GetInt64() or reader.GetDouble(), it works, but the reason I'm writing that question here is because I took this class from one of dotnet's open source projects on GitHub and I doubt that I really need to change the class. I believe the problem could be in my JsonSerializerOptions.

I'm trying to implement the following API Endpoint. Due to the fact, System.Text.Json is now preferred over Newtonsoft.Json, I decided to try it. The response clearly works, but the deserialization doesn't.

I pasted the response into an online converter and it used to work for a bit, but then it broke again once I put the comments.

How do I fix it? I would also like to throw an exception if it fails to deserialize it.

I'm trying to make some candlestick with plotly and I just have one problem: I don't want the slider from the bottom to show up, I just want my whole graph to be displayed.

I read some documentation and sliders=list(visible=F)) should do the trick but if you run the following code, the slider still appears. Any help will be much appreciated.

How do I place an order for futures? I am getting two errors: "The required timestamp parameter was not sent, was empty / null, or is not well formed." OR "The signature for this request is not valid."

I use the function to find the maximum in a sliding window of size 100, and in addition to finding the maximum, I would also like to get the time from the "open_time" column corresponding to the maximum value in the window. How to get this value correctly?

I am trying to create an api that connects into the Binance API using node and in particular NestJs.

In my controller I have @Get('candles') endpoint and call it by going to localhost:5000/candles. I am expecting it to return an object containing all the candleData retrieved from the Binance API. I am using the npm package node-binance-api.

I know the binance.candlesticks("BTCGBP", "4h", async (error, ticks, symbol) = {... I am using is getting the data as inside I log the data received and show candleData.length in the console and it returns 100 candles as requested.

My issue is resolving the promise that this npm package returns so that I can return it via the /candles endpoint. I am used to angular and observables and I am getting a bit confused by async and await.
