There is a tutorial on this new feature in the Hobby Exchange here:
https://huobiglobal.zendesk.com/hc/en-us/articles/900000106026-Huobi-Perpetual-Swap-Tutorial-Web-page-I read the explanation and found that there are significant safety precautions and interesting things to reduce the risks.
In fact, I do not like margin trading or futures trading because I am not very expert in this type of trading and I find it very risky.
The main reason that I and others refrain from this trading is the presence of significant risks, but with these updates and tools to trade safely and reduce risks it will be useful to attract more people towards this type of trading.
