Looking at chart of VNET today. Looks like a breakout:
1) MACD fast line crosses over slow line.
2) MACD crossover occurs above 0.
3) New 52-week high
4) Increased volume on breakout.
I took a long position on VNET today. (Just a smallish position).
In at $10.60 (just above the high on July 3, and above the previous day's high). My stop-loss is slightly below 13-day EMA (currently at $9.95) so I set my stop loss at $9.75. My target here is unknown. A 10% gain would put it at $11.66, 20% gain at $12.72. I will have a trailing stop-loss on this one to slightly below 13-day EMA.
Good luck out there!
