As an example, I scan for fractals. As soon as a new fractal is formed an alert pops up. I do this on different timeframes. But when I open the terminal I would like to know where the last fractal is. So I have to loop back. But I need this loop just once. Then the indicator scans for real time...
I'm using metatrader to deal Stock market assets. When I see the default value on the chart, do I see the BID VALUE or the ASK VALUE?
Or is a separate EA for every _Symbol or maybe _Period  better or more precise for some reason? Logic suggests using one EA is more efficient than attaching the same EA on 20 different charts because the simple act of loading many different charts seems to lag the platform. Is that all there's to...

Can the fact of the bar closing be considered a 'change' - the bar was open, now it is closed... the bar was index 0, the bar is now index 1 - surely this is considered a...
