Microsoft release quantum computing simulator

Microsoft release quantum computing simulator
This could be the biggest thing that they have done in years!

The field of quantum computing is really fascinating, and Microsoft has been focusing on this field for three years now. Recently, the company released its quantum simulator on GitHub. The software giant is calling it the Language-Integrated Quantum Operations (LIQUi|>) simulator, and as you may expect, this isn’t made for your average Joe.

Backtest when you have this powerful simulator to test your strategies in real time against simulated banks, traders, and even market makers?

Why backtest when you have this powerful simulator to test your strategies in real time against simulated banks, traders, and even market makers?

Honestly, this is a very powerful testing environment when you trading idea suddenly flops in live trading. This kind of software will help mitigate those failures with your new ideas.

I made a video on this software called FIX Agora.

Maybe this Python package open source pytqtgraph could be useful for high speed charting for trading system?

This is read only. I am having problems finding something decent for open source trading for high speed trading. I also am getting tired of maintaining a Windows system with antivirus (a necessity in itself) that hampers the performance of this system.

Got an opinion on a Python package like this? If so, let me know via my Facebook group.

Also, here are my latest private charts you can only in my Facebook profile.

  • Change in production and consumption of oil millions per barrels per day
  • Annual average gasoline prices inflation adjusted

Thanks for reading

Why trading strategy fails but is successful in historical backtesting? No walk forward theory or exchange simulator testing

Why trading strategy fails  but is successful in historical backtesting? No walk forward theory or exchange simulator testing

A great question from visitor:

 

> Hello Bryan,
>
> I was on the demo yesterday and had a couple of questions: Have you
> ever traded a live account using HFT models on the sub minute interval
> and how successful was that experience? If so, do you have a strategy
> for quantifying limit order fills or achieving fills that are reliable
> enough to use in your model? I’ve found that it’s pretty easy to

–> I have not done the live trading YET but doing lots of paper trading. As you know backtesting gives something that has totally different results. I am reading the book from Robert Pardo about walk forward testing to minimize what you mention. I have other theories that may work including running strategies in simulated exchanges which can be done with the tools I have at my disposal. It comes down to a time thing but these items will be considered well before trading with live money.

–> See above but it seems many forget to do walk forward testing or even running a strategy through an exchange simulator. As said, I got tools that do this but it just unfortunately on the back burner right now.
