Lot happening in this chart of NIO, but thought I'd just show you how a live trade looks in TradingView using Trade Station.
You can see on the right hand side where I bought the stock (added automatically by TradingView and doesn't move), and where my current stop loss is set (this one I can adjust and move up and down to change my stop). I could also add a take profit (also adjustable) if I wanted to try and take advantage of spikes - like in this case where it spiked just short of $21 before pulling back.
You can see at a value of 20% for a SuperTrail / Trailing Stop Loss where I have entered and exited the trade (as confirmed by the Trade Station buy line). You can also see the approximate gains made if you had trusted and followed the trail. I think its interesting how before and after the buy and sell the 20% signal remained true for this period.
Best thing I like about the trading integration with Trading View is how easy it is to visualise where your entry and exits are, and you can literally just drag the line up and down to change your position. Its cool. I like it.
