Good morning everyone

I saw a pairs trading webinar on the topic and found this code.

I can not understand these two pieces of code, anyone is kind enough to explain

% The strategy:

% 1 Compute residuals over next N days

res = series2 (i: i + N-1, 1) ...

- (Reg1.coeff (1) + reg1.coeff (2). * Series2 (i: i + N-1, 2));

% 2 If the residuals are large and positive, then the first series

% Is Likely to decline vs. the second series. Short the first

% Series by a scaled number of shares and long the second series by

1% share. If the residuals are large and negative, do the

% Opposite.

indicated (i: i + N-1) = res / reg1.RMSE;

s (i: i + N-1, 2) = (res / reg1.RMSE> spread) ...

s (i: i + N-1, 1) = -reg1.coeff (2). * s (i: i + N-1, 2);

end

end

Thank you very much for your cooperation

ps do you know where I can find some code on the pairs trading?

Hi,
We are doing a university job where we must investigate how banks manage their financial products that require trading, for example, they offer a fund, as they manage capital internally. Could you help me?
Thank you!

• Hello everyone!
I am an advanced trader, with many years of experience (about 15 years - 10 living exclusively from this)
I am going to give you some tips that you must know:

• So I've been 18 for about 4 months, since I turned 18 I started up an account, and basically thought I was doing amazing because of beginners luck, put in some of my savings and managed to do well, some days I would make £200, one day I even made £900, after time I lost my profits and made a loss as well. I've realised I need to spend the time analysing the market and making technical judgments. I'm trying to read more and spend a lot of my time looking at the charts. is there any advice people can give me. and is making 5% a week a realistic goal to set myself? before anyone assumes that im looking for a get rich quick scheme, im certainly not, I see every loss ive made as a lesson and ensure that I learn from each mistake I make.
any advice about indicators, strategies, how to analyse the market, or even analysing earning reports would help me.

• Does it mean that you are an expert just because you make a lot of profit? The amount of profit cannot be used to measure the value of a trader. Yes, you must be doing something right if you are making a frequent profit. However, that does not determine if you are an expert or not just by your profit. This is quite a common misunderstanding in the forex industry.
Making a large profit is only one side of the forex market. Majority of forex traders tend to lose most of the time after they have experienced profit. But why?
So many traders fall into a fantasy land where they make an endless amount of money at the beginning. Many beginner traders tend to gain profit at the start not knowing the importance of technical analysis of the market.
The experts on the other hand who stayed became wealthy and stayed that way, continue gaining profit, are all knowledgeable when it comes to the basics. Experts have dialed many ways to control their minds to be set right to be a trader.
Understanding of the market is a must know anyway. Expert traders wait patiently until the right opportunity comes. Opportunity comes to everyone.
What differentiates the experts and the beginners is that experts know when the opportunity has come and knows to take advantage of it. Making profit by luck is possible, and yes luck is also very important. But can you profit with luck every time?
How an expert trader is determined is not by how much the person gained, it’s about the precision and the frequency of results. Profit can’t be maintained by luck. It is maintained and is a result of precision and strategical execution. You shouldn’t worry because you’re not gaining any profit right now.
You should be building your skill sets to be a better trader by experiencing many trading situations of losses and wins. If you invest in your time to improve, your results are guaranteed to increase more frequently and will become more stable.
