CatBoost machine learning algorithm from Yandex with no Python or R knowledge required for MetaTrader 5
The article provides the code and the description of the main stages of the machine learning process using a specific example. To obtain the model, you do not need Python or R knowledge. Furthermore, basic MQL5 knowledge is enough — this is exactly my level. Therefore, I hope that the article will

Is there a pattern to the chaos? Let's try to find it! Machine learning on the example of a specific sample.
Actually, I suggest downloading the file from the link . There are 3 csv files in the archive: train.csv - the sample on which you need to train. test.csv - auxiliary sample, it can be used during training, including merged with train. exam.csv - a sample that does not participate in training. The
Algorithm for combining ranges of a segment - help to create
Please help me to create an algorithm that combines pieces (ranges) of a segment into one segment without intersecting segments, with a possible gap to be filled in later. Initially we have an array of numbers in a certain range, numbers can be repeated, this array is divided into segments by
The great loss mechanism
Almost everyone has non-systemic capital losses from currency or stock market transactions, and I am no exception. In this thread I propose to think about and understand the mechanism of these accidents to try and prevent them in the future. We are talking about significant one-off losses or a
Stop Loss doesn't work any more - to lose is to lose.

Evaluating CPU cores for optimisation
I suggest collecting statistics on the performance of various processors to estimate their effectiveness for the Strategy Tester in optimization mode. To be more objective, I suggest using an Expert Advisor that runs in the"Mathematical Computing" mode which allows you to minimize the use of your
Prop trading - is it a scam or is it good?
A lot of people have heard about proprietary Forex trading , but here I came across an advertisement for proprietary trading on Forts, which made me generally interested after I got acquainted with the terms and conditions. In brief, you risk your own money, but you share the profit with a

MT5 RAM memory voraciousness, problems with reading/writing large files
I have a question, my CSV file is 78 megabytes in size, I want to calculate it, as Excel is very slow because of its size, I was thinking to use MT5. I made a script that only reads data into arrays for each line (57 arrays for reading from file and 57 for writing into new file), the size of array
Gathering a team to develop an IO (decision tree/forest) in relation to trend strategies
I propose to rally to the challenge of MO in relation to trends, i.e. where the probability of an outcome event must be predicted many bars ahead. What I propose from my side: 1. a basic strategy for generating targets. 2. Maintaining a joint database of features. 3. Organizing the possibility of
Videos for the marketplace
I propose to discuss the topic of creating videos for the marketplace. Do you need videos to successfully sell a product or are they overkill and a waste of time? What about sound - silence, music or commentary? What resolution should be the file (in fact, will be used) for comfortable viewing? What
