Use of Statistics for Trading Beginners

Recommended Posts

Hello guys,

I am not a serious trader yet, although I have been aware of this forum for some time.I am at the moment interested in statistics resources.

I dont have much knowledge beyond the normal distribution curve which I learnt in school (that too vaguely).I would require some advise on how a trader should proceed to increase his knowledge in statistics for trading.

I understand from the posts here the need for hypothesis and testing of a trading idea,but apart from a general idea I dont seem to be finding a detailed resources/software or books or to be read on the matter .

Thank you Tams for answering,

I was looking out for an answer in the context of deciding whether a trading idea is workable.

The below is a reproduction of what DbPhoenix had mentioned in one of his posts.

"The essential elements of the scientific method are traditionally described as follows:

 

- Observe: Observe or read about a phenomenon.

 

- Hypothesize: Wonder about your observations, and invent a hypothesis, (sometimes one's hypothesis is initially nothing more than a "guess"), which could explain the phenomenon or set of facts that you have observed.

 

- Test a hypothesis

 

- Predict: Use the logical consequences of your hypothesis to predict results (e.g., measurable experimental values) that must be found if the hypothesis is to be judged correct -- whether it is 'complete' or not.

 

- Experiment: Perform experiments to test those predictions. (Note that great precision regarding a negative result might not be required to falsify a hypothesis.)

 

- Conclude: Failure to see the predicted results from a well designed and implemented experiment is clear indication that the hypothesis is defective. Try again. Seeing the predicted results is an indication that the hypothesis is acceptable though not 'confirmation' or 'proof' of its correctness.

 

- Evaluate: Search for other possible explanations of the result until you can propose no better account of your data. Formulate a new hypothesis which may better explain the experimental data and the original observation."

 

I am not sure how to proceed furthur from 'test the hypothesize' stage.

It is my understanding upto now that this stage involves statistics whereby I should be testing the trading idea.

I am not sure how I should be testing it to determine it is workable or not.

 

Thanks

Nalin

Check out the book: "Evidence-Based Technical Analysis: Applying the Scientific Method and Statistical Inference to Trading Signals" by David Aronson.

 

There are also several other trading system and testing related books. Just do a search on Amazon.

first, you have to come up with a Hypothesis.

 

let's just make an example...

 

Hypothesis "HHLL-1"

 

if the price trades higher than the previous bar's HIGH, the market will go higher.

 

 

you can then make observation and collect data to test this assertion.

It doesn't necessarily involve statistics. The rest of what you've quoted can be found here. And if you continue to have trouble figuring out what to look for, check here, here, here, here, and, if you are thinking about daytrading, here.

 

If you have any questions, feel free to ask.

these days you can download data into excel for free and manipulate data so easily -- I would start there. if you need a guide, start with a basic book and move your way up --- there are countless books written on excel for statistics. flip through some in the book store and read the reviews on amazon.

Get hold of a book called "Against the Gods - The Remarkable Story Of Risk" if you have some spare time. It's more historical and theoretical than practical, but it will get you thinking about all things related to Risk/Probabilities.

I just did quick search on Amazon -- these dummies books get great reviews cause the publisher can lure the best writers to the very successful brand. This one goes from the very simple to the intermediate and makes everything simple ---- and then there is a second book on intermediate statistics. I find it pretty ironic to be discussing 'LINEST array functions' in a 'for dummies' book --- don't let the title fool you. This books materials starts very easy and then takes off with useful topics.

 

I was flipping through a C#.net programming book for dummies --- I am way below dummy I guess cause C# is dense stuff. I mean seriously, how many dummies can program in C#?

 

Amazon.com: Statistical Analysis with Excel For Dummies (For Dummies (Computer/Tech)) (9780470454060): Joseph Schmuller Ph.D.: Books

 

For a good overall reference book on excel, I recommend this one:

    • Question: To those that had/have cancer, what were the signs that made you think “something is not right here” to make you go see a doctor? Answer: So, 5/25/2018, I woke up, got ready for work, and as I walked to my car, I started gagging. Like something was stuck in my throat and I needed to clear it. And then it went away.   But 10 minutes after that, I was T-boned at 40mph on the driver side door. But what made me see a doctor was while my muscles felt better and bruises were going away, the gagging still continued, I started having fevers, my neck felt swollen, I was having such a hard time breathing, and I'd have random sharp pains in my chest, but not from where the seat belt saved me.   2 weeks after the accident, I finally see an urgent care doctor, who looks me over, tells me I'm fine, but luckily requests a neck X-ray. And I ask for a chest X-ray, which he rolls his eyes but let me have (most of my pain was in the neck, so I understand).   The very next day, he calls and says “So, that chest X-ray shows there's a 4 inch mass on your heart and lungs, and your lungs have been filling up with fluid, as well as in your pericardial (heart) wall. We need you to come in tomorrow.”   Turns out the big mass, due to the accident, caused my heart and lungs to tear and fill with fluid, the swollen neck and gagging was caused by 2 metastasized tumors, and the fevers and weight loss were symptoms. Stage 4b Hodgkin's Lymphoma.   But thankfully, we went very aggressive with chemo (and had a lot of bad side effects that don't normally happen to patients), and now I'm about 16 months cancer-free. Yay lucky X-rays!

    • As a man, the reality of life is the harshest part. I don’t mind looking older or becoming weaker over time; it’s nature.   Have you ever heard that the only people who will be loved unconditionally are women and children? Men will only be loved as long as they can provide until they are no longer needed. It doesn’t matter if you already did your best to get your kids to the best school or get the best things for them, if you stop before they’re done with it, there will be no thank you. The only thing they will remember is that they have to quit school at 15, ignoring all the previous 15 years of life you provided for them. The only people who will accept you, no matter what, are your parents. But in this situation, you might be that ungrateful child.   EDIT: Wow, I didn’t think this would get so much attention.   For those who disagree, I can only say that everyone has their problem. If you don’t get the chance to face such a thing, be grateful.
