    Sorry, another Covid thread :-)

    The tweet seems to be missing something. I'm sure that was a simple oversight.:rolleyes: He says, "goals for the next five years, and one of them was by 2023 we will reduce the number of people in the world that cannot afford our medicines by 50%." timestamped:

    Creating Trading Rules With Intermarket Relationships

    I looked at walk-forward optimization with a rolling window. https://ungeracademy.com/posts/how-to-use-walk-forward-analysis-you-may-be-doing-it-wrong And, I found a 2020 paper (attached) describing the authors' use of genetic programming with walk-forward optimization. They combined some...

    Creating Trading Rules With Intermarket Relationships

    I wrote the software in C++ and opencl with perl and shell controlling it. It uses linear genetic programming mostly based on the ideas from this book The inputs are daily close prices for the current trading day and the previous 21 trading days for the assets I wrote in the post above. This...

    Creating Trading Rules With Intermarket Relationships

    Here is an example of rules created through genetic programming to simulate trades in one asset with data from other assets. This example uses daily close values to simulate trades entering long at the next trading day's close value of NASDAQ 100 with and exiting at the close the next trading...

    Using Astronomical Data to Create Trading Rules

    Here, I present different types of rules created by genetic programming for simulated trades entering long on the next trading day's close S&P 500 and exiting on the close one trading day later. Inputs are the same as in the previous post. Before, the rules were comparing an input with a...

    Limitation of Characters

    Posters should learn to use the QUOTE feature when pasting a long article If a QUOTE is expanded and a post becomes too unwieldy, refreshing the page restores the QUOTE to it's original size on the screen. I suggest limit the number of characters in a post but not including text hidden in a...

    Let's think about the devil for a moment.....

    In my opinion, Mr. Biden has too many "senior moments" to be a good fit for President of the U.S., as does his current chief rival. Regarding the spelling you mentioned, it's easier to get into Colombia than Columbia.:)

    True. He said "We ended cancer as we know it." It's not exactly the same wording, but that still doesn't make his statement remotely true.
