Here is what I'd do step by step if I were to start over with quant:
Please retweet so that as many people as possible can find out about those resources.

First of all I would learn the basics of python so that I can start implementing things asap.
Good Resources:

Then I'd learn some linear algebra, quant involves working with a lot of data and transforming it in various ways.
You won't get far without knowing lin alg.
I think those are the only prerequisites you need in order to get into quant.
95% of the stuff you learn won't stem from quant finance but may come from for example:
-Neuroscience
-Physics
-Engineering
and many more.
6/n
You will learn most of this stuff as you do different projects.
That's what I love most about quant, there is an infinite amount of stuff to learn from all kinds of professions.
Now that you know Lin alg, Stats, Data Science and can code you are ready to start with quant.
7/n
To finally start learning quant I would first read all 3 books written by @chanep in the following order:
Those books will give you an easy overview of different topics in quant that you can explore later on.
8/n
Here are some other general quant books I'd read:
-Finding Alphas: A Quantitative Approach to Building Trading Strategies - Igor Tulchinsky
-Frequently Asked Questions in Quantitative Finance - Paul Wilmott
9/n
Now I'd start reading books on more specific topics.
Options:
-Option Volatility and Pricing - Sheldon Natenberg
-Options, Futures and Other Derivatives - John C. Hull
-All of @SinclairEuan 's books
10/n
ML:
-Machine Learning for Algorithmic Trading - Stefan Jansen
-Advances in Financial Machine Learning - Lopez de Prado
Time Series Analysis:
-Analysis of Financial Time Series - Ruey S. Tsay
Signal Processing:
-Digital Signal Processing: An Introduction - R.Anand
11/n
Portfolio Management:
-Advanced Portfolio Management - Giuseppe A. Paleologo
-Quantitative Portfolio Management - Michael Isichenko
-Advances in Active Portfolio Management - Richard C. Grinold
12/n
This should give you the basic knowledge of the topics you come across the most in quant.
From here you can specialize even more. You mostly do this by reading, implementing and improving research papers and then working on coming up with your own ideas.
13/n
An example from statistical arbitrage:
Implement the SMRP paper in crypto, figure out what works and what doesn't and try to improve it.
How many assets do you want? Is the portfolio mean reverting enough? Is it volatile enough? etc.

I hope you enjoyed my first thread. Feel free to comment other resources under this post, I will work on updating the thread and adding your suggestions.
If you have any questions feel free to dm me.

Moving Averages don't do well when data changes abruptly.
We can do better by solving a 100000-dimensional Second Order Cone Program.
Let's talk about Total variation denoising:
When to use it:
If you have a noisy dataset whose mean changes abruptly and you want to filter out all the noise and get the underlying process then Total variation denoising is perfect.
In the image below the black line is what we get after denoising.
Definition:
We have our original data x_1, x_2, ... and want to construct data y_1, y_2, ... such that the total variation V(y) is kept low while also keeping the sum of squared errors between the original data and our estimate y E(x, y) low.
This article gives a big overview of all the literature on market making models like the popular paper by Avellaneda & Stoikov and other popular papers in market making.
Most of those papers use convention that's used in real market making systems like fair price, spreads, etc. so you should get familiar with them.
Why more leverage doesn't necessarily mean more profit and how to find the optimal leverage.

Let's say you have $100. You do a trade, make 1% and are now at $101. You do a trade again with your $101 and this time you loose 1%.
Intuitively it would seem like you would be break even but if you do the math then 0.99*$101 is actually $99.99. You lost a penny!

Above is an example of what would happen to your equity if you did this 1000 times.
The bigger your returns are the more extreme this becomes.
If you have a 1% loss you only need a 1.0101...% return to make back your losses.
With a 50% loss you need a 100% return.
