I'm trying to return and store a nested JSON string in Python which I intend to use to serve the image from the URL string in my program. The JSON payload is this:

I'd like to convert timezone of a Python's datetime object, from US/Eastern to UTC.

What I did was first making datetime object of US/Eastern timezone, converting it to UTC timezone, and converting it back to the US/Eastern timezone. It is expected the first and last US/Eastern timezone datetime objects are identical. But it turned out that the two are printed differently.

What am I missing here?

Code:

I found a website that pushes darts scores. Each time a new score is published, I would like to be notified.

I am trying to place limit orders with the interactive brokers python api. The limit price is based on the delayed market price. The code for this is the following:

So as an exercise im trying to figure out how to locally verify a git commit signature.

As an example I am using https://github.com/ethereum/go-ethereum/commit/0a68558e7e025afebf67b81bf48ecb8b0fa7c06d.

The public key for this sig is https://github.com/web-flow.gpg.

When I run the following

I was trying to extract the number with 2 decimal places from my APIs input. These data are shown with text and comma but I only need the number with a decimal. I'm pretty sure this isn't the right way of using regex101. I'm a beginner in coding so I don't have much knowledge about a Regular Expression

1: {"symbol":"BTCUSDT","price":"34592.99000000"}

Attempt to extract: 34592.99000000 using regex101 "\d+........"

2: {"THB_BTC":{"id":1,"last":1102999.13,"lowestAsk":1102999.08,"highestBid":1100610.1,"percentChange":2.94,"baseVolume":202.54340749,"quoteVolume":221380256.57,"isFrozen":0,"high24hr":1108001,"low24hr":1061412.72,"change":31496.06,"prevClose":1102999.13,"prevOpen":1071503.07}}

Attempt to extract: 1102999.13 using regex101 "\d\d....."

These attempts only get me close but not 100% to the target, I believe there is a right way of doing this.

here's my code

The IBKR TWS (Trader Workstation) is a tool for managing stock orders in the stock market, by Interactive Brokers. They provide an API to automate orders, like placing orders, cancelling orders, and more.

I'm creating a program to handle executed orders in my Trader Workstation using the Interactive Brokers Java API.

I'm having trouble detecting when an order fills.

The documentation describes that the execDetails callback (which is an EWrapper method, see code below) is invoked when an order is filled, but I tried using that and the execDetails callback was never invoked (I tested this by logging the reqid int in that callback, and I never got any log).

I have also researched about the completedOrder callback, which I'm not sure if that's the callback that will be invoked when an order is filled, because I tested both callbacks with a simple log, and nothing was outputting in the console.

I don't understand the reqExecutions function and whether I need that. I have already read the documentation on this callback, and I don't understand what I'm doing wrong. I want to know I how can detect when an order fills, or executes in the TWS using their API.

Here is my current code:

I came across arguably the smallest HTTP server in docker (written in assembly), and I would love to see it in action!

I think they took the code from https://gist.github.com/DGivney/5917914 :
