synthesize rules that take into account strictly some specific events in a specific sequence, as well as take into account the price at which these events occurred.

Here is a certain pattern


Here is this pattern in prices

here is the same pattern

The problem here is similarity without correlation. This is where the metric of economics began) Rows are similar, but there is no correlation between them. I like the idea, it's more like creating a library of states, but purely incremental lags are not enough, we need more predictors, if at all. Nobody forbids to find repeating combinations, if these combinations are distributed on large sections more or less evenly, there is a chance.

What lags... you will kill the price !

A state is a rule, it could be anything - a candlestick combo, a level breakout, the level itself, a volatility kickout, whatever

The states in the right order create a pattern of any size.


No BP forecasting algorithm is able to look for such patterns

Anything )))) a candlestick combination, a breakout, a return to the mean, a trend change or an extremum, an ejection, an ejection/volatility change. Nothing else comes to mind that can be described mathematically.

To add a major and minor TF or several more ones may be necessary. The idea is clear at the top, but the stationary sequences have not been found yet. Although usually look for the maximum on the target and junior.

No BP prediction algorithm knows how to look for such patterns

That's how you set the recognition task. BP prediction and image recognition from incomplete data are different tasks.

The market is not BP

Cool) what then. The values at a point in time are a series.

I do not know ...

You can represent anything as a time series, there is always time.

But if no BP prediction algorithm can predict the price in any way, isn't the answer obvious?

 
You see, there's nothing to answer, because that's how it is when you think about it.

Time can be replaced by number. Any prediction is probabilistic. The price is too steep. At least a direction or range would have been nice. In the range of stationarity it is possible to make a forecast, the question of determining the boundaries of stationarity only by history, the task without a 100 percent forecast, but not zero.

What will it do? Nothing.

Valeriy Yastremskiy:
At least the direction or the range was already good. It's possible to make a forecast within the range of stationarity. The problem is in the determination of the stationarity boundaries only by history, the problem is without a 100% forecast, but it's not zero, either.

It's all working with BP again, it won't work
