ARK may break the wedge soon. Watch for it. For now, you can buy low and sell high in this pretty little channel it has formed and make yourself some easy profits. Stop loss is if it heads below the channel. Working a 25% strategy, 5 minute chart and expecting some volatility. Buy low in the channel and sell if the 5 minute moving averages turn negative near the top of the channel, or at whatever point you're comfortable with.
Future trade: Some of the pro traders think this thing could break the wedge and we would see some huge gains. Watch for that, then buy on the dip to resistance at the top of the wedge. Resistance will be the wedge top once it breaks, with a stop loss below the wedge top.
Sorry but your prediction did not factor in the crash caused by BTC sudden downtrend , fortunately though it still seems like this will be a long term hold for a nice double.
