I have a question about the API. I am using ccxt, when I do hollaex.fetch_closed_orders(), my order done at the market does not give the price but I can see it on the website. For instance, this buy order return None
In this case you better get the price from your trade history instead of order. Because market order gets traded in different prices it does not return the price in the order endpoint.
Great to hear that. Order is referred to the users action which is what user has sent. Trade defines what happens afterwards to that order by other users.
