Economic news indicator needed

Hello,

I need an economic news indicator. I know there are several indicators for this on the market but none of them is actually fitting my needs, thats why I opned this jup now.

What I need is an indicator like this: https://www.forex-station.com/viewtopic.php?p=1295364445#p1295364445

I do not need a panel like you can see in the screenshot on that site..but what I want is to have the news marked on my chart similar to that indicator.

The indicator should have the possiblity to alert me x mins before low impact news, x mins before medium news, x mins before high impact news, x mins before speach etc.

The next function that I need is to have buffers for the different kind of news impacts. These buffers need to work as described one line above (e.g. 30 min before and after High Impact news it needs to show in the buffer a specific value for example 1).

So I can programmatically use the buffers in other indicators via iCustom and then avoid opening trades during that time.

I want to use the data of this economic news calender for the indicator: https://www.myfxbook .com/en/forex-economic-calendar (to get the data in xml format you need to be logged in, i think this needs to be done via a webrequest)

It also needs to work with backtesting.
