lines have been followed very well by XVG, stretching as far back as 21 December for support. Right now it's making a symmetrical triangle inside a bigger one, looks ready to go and is showing oversold. It could potentially drop down to the support line, but I don't think it will... I think so because on the 4H chart, XVG is neither overbought or oversold, meaning that it could potentially go higher now.
Since we're pretty high up already I would say to set a stop loss a little bit underneath the teal line. If your stop gets triggered we will have another buy opportunity at the bottom support.
