Previous down movements stopped by buyers at the turn of $ 200
The slow moving average on the chart is almost horizontal throughout December.
There are all signs of a flat trend.
Trading in a flat trend is very simple: buy from the lower border and sell at the top one.
The only difficulty you can face is the fact that there may be shortages or, conversely, jumps from these lines.
Exit from the range - the day closing outside of it (and preferably two days for reliability)
Recommendation: Buy for $ 200 to sell for $ 400
