Andrey Dik:
What if a couple of trades turn out to be the main profit, and thousands of others turn out to be small losses? - It's kind of a bad idea.
Absolutely right, the disadvantage of all target criteria for TS is that they do not take into account the number of trades. That is, on a small number of trades you can randomly obtain a large value of the criterion.
 
Yury Reshetov:
Exactly right, the drawback of all target criteria for TS - they do not take into account the number of deals. That is, on a small number of trades you can randomly obtain a large value of the criterion.

Well, why all of them... You can add arguments to the formula that take into account the ratio of profitable/loss-making trades and the total number of trades.

 

I've been through the whole thread.

You guys are digging in all the wrong places.

 

It turns out that there is a tool to evaluate R models

Azure Machine Learning Studio is a GUI-based integrated development environment for constructing and operationalizing machine learning workflows. The basic computational unit of an Azure ML Studio workflow (or Experiment) is a module which implements machine learning algorithms, data conversion and transformation functions etc. Modules can be...

Where should I dig?
 
Andrey Dik:
And where to dig?

I join the question.

Yes Vadim where to dig?

p.s. glad you were unbanned

Welcome out of the ban, first of all. I hope I don't have to complain about you again.

You are our demokrat.

It turns out that there is a tool for evaluating my models

How to evaluate R models in Azure Machine Learning Studio

I understood that it's just a nice visual programming shell, inside all those "modules" is the usual R code. Basically, the data is divided into two groups train/test, and the model is trained and tested as standard, all the same can be done in rattle.

More subscription to the service is expensive, 100sd for 25 hours of calculations per month. Will save only if their cloud is more productive, and an hour does much more than the usual computer.

At the end (Evaluate module) for the model is calculated <<"Accuracy", "Precision", "Recall", and "AUC">> etc., there is nothing new here too.
