Buy: the ideal entry would be to expect a crossing of Kinjun (pink line) by Tenkan (blue line) from below and with force. However, they are a couple of resistances to overcome, probably the price won't take off until it cross these levels and our entrance should be there.
Sell: around 15.5 - 17.5 USD
Stop Loss: ~ 12.5 USD
You should not invest more than 10% of your available capital to trade.
