How best to balance classes, who uses what methods?
And I would like to ask what predictors in your opinion are interesting, can I ask you in person?)
What is the best way to balance classes, who uses what methods?
There are functions
The downSample will randomly sample a data set so that all classes have the same frequency as the
minority class. upSample samples with replacement to make the class distributions equal
In general, I recommend to study caret: you can use it as a "what happens" tutorial - it contains tools for the full cycle:
You can get quite industrial designs.
PS.
I don't think anyone will reveal predictors - that's the most important thing, and models are a matter of technique and diligence.

Well, it was just a "fool's errand" to ask. After all, they create silly branches, "how to triple the deposit", "tell me a profitable Expert Advisor," etc.
But, I need advice with indicators, it is clear, it is the first thing that comes to mind. But here is something unusual, where very few people have dug.
Well, it's just a "foolish" question. After all, create the same silly threads, "how to triple the deposit", "tell me a profitable adviser," etc.

Take digital filters from the last part of the article. It will be useful, I think, to read all the previous parts as well.
Good luck

Models are created from ready-made stuff, and here you can use a blank sheet.

I do the balancing when sampling from the end-of-training label deep into the history, in a loop, until the number of samples reaches a given number and is compared.
In the simplest version, I use a set of bars as predictors - the integral value calculated by a given formula, which is laid down as input data during training.
Actually, the best predictor is the price series itself. Any processing is a loss and delay of information. And if you also take into account that we do not really know what kind of information we need, then...
I work with 1m, and a delay of even 30 seconds is the death of the system. And even very simple indicators give a delay of 1-3 meters.
Even if you work on an hourly timeframe, the delay on the indicators will be 1-3 h.) In any case, 1-3 candles, no matter how you spin it.
ZY2 Another plus of time series - we don't need to pick up predictors. Just learn to use BP itself in this capacity.

How can you not respond with a phrase like this. The hourly chart can be viewed under a magnifying glass 15m, 5m 1m. It is sad, gentlemen.

Don't be sad, I know.) If you feel comfortable, you may continue.
