For time, do not set an Optimisation step.

The confusion comes out in the names.

fxsaber:
You can't set an Optimisation step for time.

So enum never allowed to enter a step. Only "start" and "end". And this has been the case since forever (a very long time ago).

Well, enum has never allowed you to enter a step. Only "start" and "end". And this has been the case since forever (a very long time ago).

That's right. Only in the MT4-original version it is possible to set a step for time, while in the MT5-variant the user is artificially deprived of this possibility.

Moreover, it is much more convenient to type a number than to choose with the mouse in the drop-down list.

Nope. When the user enters the date (or time), which is usually done via string, the user should not be trusted with manual input, because manually you can make up a number that cannot even be read. Besides, we should not forget that enum is great for optimisation.

And this was discussed a while ago. Remember the topic.

What does commonness have to do with it, when in the MT4-original it is not done with string, but with int?!

Besides, we should not forget that enum is excellent for optimisation.

If enum does not fit perfectly - you cannot set a step.

And this was discussed a while ago. Remember the topic.

I remember thatdisgusting topic. It has nothing to do with this EA. Except that the author of this conversion and the topic coincide.

What does regularity have to do with it, when in the MT4-original it's not string through the arse at all, but normal - through int?!

It doesn't fit enum perfectly - you can't set a step.

Nobody cares about what was in the old terminal.

If you want a step in enum - write to ServiceDesk, I am not a terminal developer and cannot give you a step when optimising enum.

time has always been set via int (if you write it as you do in your code, hour and minutes separately).

They were written using int just for the purpose of optimisation and for optimisation of these parameters a step is fundamentally needed.

No one has ever done it with enum, because users are always sane and sensible.

It's about the new terminal.

My experience is just the opposite. They are all wizards - as soon as you give them the freedom to enter something manually, they will make up such a mess. That's why enum is the best option:

1. it is oriented to the user who has a computer mouse integrated into his hand (99% of all people who work with computers :) ) - two clicks are always easier than clicking and entering numbers
2. guaranteed that there is no exceeding of the range of values during optimisation, i.e. by the example of a clock, the input parameter is guaranteed to be in the range from 0 to 23.
