maybe you can tell me something - here https://www.mql5.com/ru/forum/150135

thanks

Here's a hint. On the basis of a given numerical series one can construct a huge (in the limit infinite) set of functions. Narrowing of the class of functions in question, concretization, can be done by introduction of constraints that satisfy one or another requirement. In this case, the task of forming these very requirements comes to the forefront. These requirements may be very different, both coherent and contradictory.

If anyone has a Moderation in the marketplace Pure maths, physics, logic

And if you change the row just a little bit, all those functions become useless ))))

And if the requirements are contradictory, how will it be possible to fit them into the Expert Advisor and at the same time, it's simply impossible to do?

And if there are contradictory requirements, how can you fit them into an EA and still make it work, it simply can't be done?

Well, that's not what we're talking about.

And contradictory requirements do not mean unrealisable - but that is the challenge of implementation. Conflicting requirements are inherent in the vast majority of technical problems.

And how to solve this issue so that the contradictions don't interfere with each other? I'm just new to this business.

You should first formulate an optimization problem and then solve it. There are various methods for solving optimization problems that have their own areas of applicability. Consult the relevant literature.
