Actually no. because at Bitmex only supports short buy and sell orders, and we can only see the contracts tilting to either side. The volume is displayed in the Coinmarketcap field for coins and you can view it. In addition, the MACD - histogram and volume trees below the analysis charts also show the trend of selling or buying. You can check it by adding MACD indicator.
There's a lot of tools that can help us determine some scope of analysis. What I see here in Bitmex was good for a quick trades and won't sustain for long period of time. There comes a good alternative on small volume exchanges, buy and sell will immediately increase faster gains.
