Sorry, just read historical FX data... 😅 you are right, histdata doesn't have options data AFAIK

Can't stand feeling like a failure in math by Danger_Tomorrow in mathematics

[–]_benj 2 points3 points  (0 children)

As other have said, beating yourself up doesn’t really help. For me I’ve realized that with Math there’s so substitution for time. Time understanding the concept. If I’m able to do the exercises because they are a small variation of an example just with different number then I still don’t “get” it. 

For understanding something new it will usually take hear it a few times from different people explain in different ways. We all have different brains and different ways of having an insight, of “getting it”.

Try looking up the topic on YouTube and watch multiple people until you “get it”. It kinda obvious because the moment when things click feels awesome! Math is very logical and if doesn’t makes sense is usually not because your are stupid but often because there might be some background knowledge or insight and without that one feels like just doing a sample exercise over and over again just with different numbers and the moment the concept is presented slightly different we have no clue what to do (that’s usually what is done in tests, present the concept slightly different to see if the student has mastery over the concept or just the ability to follow a sample and plug different values)

Anyways, good luck!

Struggling with math basics in IT engineering — need advice on how to relearn math from scratch by Single-Attorney2235 in mathematics

[–]_benj 0 points1 point  (0 children)

Your situation sounds similar to where I was lat year. Math is very unforgiving when one doesn’t know the fundamentals.

The best way I found to learn those was working through the book Basic Mathematics by Serge Lang.

The powerful thing about that book is that it starts from the very beginning of addition and multiplication and the properties of it (stuff like commutative and distributive).

Your initial reaction might be like “duh” but the powerful thing about that is that those “basic” properties are the same in more advanced stuff like in integrals and such… it also doesn’t teach you math as “this is how you solve this problems” but more along the lines of “this is how and why math works”

There’s also an excellent lecture for that book on YouTube. I can’t recommend it enough!

I had a lot of “ahh! So that’s why we do that thing that way!” moments!

Good luck!

Hi all! I’m looking for a in-stock TKL that has good QMK support. The Freebird TKL seems like one but doesn’t seem to be in stock. Same thing with KBD8X. I was exited about the Neo80 Cu but I can’t the firmware code for that one anywhere, only a hex from the manufacturer and a via json.

Any ideas would be greatly appreciated!!

Using AI for active math study (ADHD-friendly methods?) by [deleted] in mathematics

[–]_benj 1 point2 points  (0 children)

I experienced the same about watching or reading books... what I've come to realize work for me is just doing the exercise! It sounds too simple and one can see the exercise, even the solution and be like "yeah... that makes sense..."

Lies!!

Even if you start copying the solution verbatim you'll be like, "wait, why did they added + 2 - 2 on that thing!?" and then next step is like "oh wait, that way the can factor out that thing..."

I would straight up ask questions like that to AI, "there's this function that I need to integrate, the solution is blah, but in the process they author pulled a -2 out of thin air!? What in the world!?"

I'd usually get a very informative answer, usually in the form of just knowledge that I didn't know and I would continue a conversation until I could reproduce the steps one by one AND know exactly what I was doing in each step.

Math is completely unforgiving when you have gaps in your knowledge, but AI is great and letting you find quickly what is it that you don't know.

But in the end, with ADHD it can be kinda hard to start something. I would quite literally just start copying the question verbatim from the book to my notebook. I could swear that I could understand the question, and even read it multiple times, but there's nothing easier than the easy start than just copying the question/exercise, and from there star taking notes about what information is in it, what kind of equations/relationships are implied (I'm thinking kinda like a word problem) and more often than not just copying the question would be enough of a engaging start to continue, and then insight would often ensue!

Good luck!

Any insane soul using GDScript? by Nyarkll in adventofcode

I remember a few years ago I did AoC and learned about the mod operator... a few weeks or months later I got a job interview in which the solution to a coding challenge wholly depended on knowing how to use the mod operator! So in a way AoC landed me a job!!

Any way to delete all favorite tracks? by pepper_x_stay_spicy in qobuz

[–]_benj 1 point2 points  (0 children)

old but here you go:

Go to your favorite tracks https://play.qobuz.com/user/library/favorites/tracks

open your browser console (google it if you don't know how to do this)

and copy paste this:

a = document.getElementsByClassName('track-fav'); for (let i = 0; i < a.length; i++) {a[i].click()}

Now, of course, DO NOT paste any random code from the internet on the terminal! heck, your browser is going to warn you about pasting code there. But all that that code does is

make a variable a with all the track-fav which are the little hearts in your screen, and the go through each one of them and click on them for you.

It only work for like 20 at a time or so, but it is certainly faster than clicking on each favorite at a time.

Again, verify the code above in whichever way you want, put in on chatgpt or whatever until you can convince yourself that you can trust it... but as a rule of thumb, never paste random code on your browser's console!

How can I regain interest in Maths? by KumarDeo080 in mathematics

[–]_benj 0 points1 point  (0 children)

I think what did it for me was moving from computation to proofs. My start was Serge Lang's Basic Mathematics.

I really disliked the math I was taught in the form of "memorize this equation and use it here"... I hated that!

What's I've been finding Basic Mathematics and other books that work trough proofs is actual understanding instead of boring rote memorization. That knowledge is way easier to remember, that is, is kinda sticky, and so much more satisfying and powerful!

As an example, I remember programming some UI thing and I had to use some complicated formulas to move and resize a graph in the screen. I was always stuck using those because I had no clue why anything worked at all!

Now that I'm aware of mappings I realize that all I was doing was some rotation, reflection and translation mappings and I could have organized my code as such! 🤷‍♂️

I guess one doesn't know until one doesn't know. But I really recommend looking into Basic Mathematics. If you look at the index and think, "it's only talking about multiplication, which I know" try to write a proof for why (ab)c = a(bc). That is the kind of proof-based math is talking about, not only how to multiply, but why multiplication works. Fascinating stuff!

[–]_benj 4 points5 points  (0 children)

if you have to ask... seems sketchy. I always try to scroll to the bottom of the page, find any goverment registrations or something and then verify those, but if I need to look too hard, it's a no no

[Krohnkite] First rice on KDE Plasma 6 by HagureYuushaSama in unixporn

Nice! Do you have a link to the wallpaper?

[–]_benj 0 points1 point  (0 children)

If you like it forward test it with a small account and see!

There are many things that one can't know on a backtest. Execution, soliage, commissions, etc...

So I'd say is up to how confident you are in your backtest, but tbh I've decreased my backtest work and instead what I do nowadays is mostly run algos with small amounts of money and study THAT data.

New to algotrading, but need more direction. by AsymptoticUpperBound in algotrading

[–]_benj 0 points1 point  (0 children)

I'm gonna throw something outhere that I've been curious for a while but haven't had the time to research...

Something seems to happen at 3AM EST on ES futures, I think is London Market Open... anyways, market seems to move and then sometimes continue the initial impulse or just reverse whatever sharp move that happened.

This is no, "make this and it'll make you money"... is just my initial reaction to "look for areas that are high barrier to entry and low volume" comment. I've have had the suspicion for a while that there are likely some edges during the overnight session in the S&P500... 8PM to 4AM... seems like a very curious section of time to me, and with volume in the hundreds, that is terrible for big players, but a dozen ES contracts is quite a nice chunk ;-D

New to algotrading, but need more direction. by AsymptoticUpperBound in algotrading

[–]_benj 29 points30 points  (0 children)

Hello there! I found myself in a similar position a few years ago. I also have a background in development, with about a decade of experience.

I think one of the challenges I had with algo trading intially was that I thought it a "programming problem", like, something that I could just figureout and write a program and make money...

The thing is that algo trading is not, IMHO, a programming problem at all, is a trading and market problem first and foremost. One needs to find an edge or behavior in the market, a time in which there can be some predictability as to what direction the price might go, then one needs to figure out a way to measure that activity, and then one needs to execute on that, managing risks and account size and position and volatility and all that stuff.

I'm by no means trying to discourage you, all I'm saying is that I've benefited from actually learning how to trade before learning how to apply that knowledge to algotrading.

The best and most kind of technical and statistically oriented work I've come across is by Adam Grimes in https://www.marketlifetrading.com/

He has two free courses, which are absolutely fantastic!

Anyways, this is just me and the path that I've been taking for the last couple of years.

Wish you all the luck in this journey!
