This is a median line in the weekly chart is one i have been using it for a long period of time. I have marked in the chart price action at it's parallels to see how the slope of price is working in a fantastic way. Price has now reached the sliding parallel which has acted as resistance several times previously. Four days in a row it didn't manage to break above it, something that makes us believe that the level most likely will hold once again. Keep an eye for a sell setup at current level and you may be in a trade that will last for a long time giving you huge profit.
@Nhatrang, Basically it depends on how you will trade your setup depending your strategy. But overall a realistic tp would be the quartile of the fork (where the arrow shows). As you may see, previously we have had great support at the quartile.
