It depends on the exchanges. In Bitsdaq, you can see more than 50 orders have been placed, and so are Crex24. but on large exchanges like Binance, Huobi, Bithump, I don't see that, because their trading volume is too much and listing lots of orders is not so useful. but you can measure buy or sell orders right now by looking at the volume at the bottom of the chart, which is quite accurate and shows that the sellers or buyers are getting stronger.
