News filter improvements (holidays)

I would like to suggest a couple of improvements.

First idea:

Now the news about the holiday (All day) is tied to a specific time.

This is what it looks like in visual testing:

And so the holiday is displayed in the news file:

It turns out that in order to exclude the entire holiday from trading, you need to set a time interval per day. (using "minutes before" and "minutes after" parameters)

But this is not possible for two reasons:

- the interval is also used for regular news

- all holidays have their time in files:

Therefore, as an improvement, I propose to change the logic and untie the holidays from the time interval and simply indicate that if there is a holiday on this day, then do not trade all day.

Just in case, I attach a set with which I checked the operation of the function - these are the default settings + the holiday filter is enabled and the parameters are set "DST mode" = "DST Europe" и "GMT offset" = 2 (Roboforex UTC+2 (Eastern European Time, EET) https://roboforex.com/beginners/info/forex-trading-hours/ )

test holiday filter.set

Version CP - 2.55.1

Second idea:

If idea #1 is implemented, then an additional parameter can be added that would indicate whether it is also necessary to trade the day before the holiday or the day after it.

I will give an example when this can help - 4 july (Independence Day US)

On this day, there is most often no volatility (flat), and after that there is a strong movement. It would be nice not to trade on these days.

In this example, the next day there was not even any other news, and the movement was strong (for no reason not adequate):
