If you want to go short on an investment, then you have to use a short chart. 15 minute or 1 hour chart is okay if you're looking to hold something for a day.
This Vislink tech had quite a pump today following that news but it also had a big sell off while bottoming out and closing at a higher low.
Historically on the MACD these spikes are always followed with a move to the downside but I did draw a resistance with minimal data and if it continues upward it will form a rising wedge with a 68% chance to fall to the downside so If it does well tomorrow and stays on track ( for a change ) the best time to sell is early on the 20th. The long line is the long term resistance it's connected to the downtrend further back on the chart which is a 2nd reason I would think this is bearish. A short trade indeed, but it already pumped.
Additionally, this is not financial advice. TA is less useful in a global pandemic. I do think investors will still implement TA and agree this stock already pumped. As for a long term hold, the MACD shows bullish signals over the past 8 months.
Yesterday would have yielded a nice 0.03 cents if you never sold at the top ( hardly anyone ever sells at the top, only the rich folks pumping it. ) I would sell that.
