History just list the transactions made but buy and sell order for higher price isn't listed there. I was looking for it because I bought STA at a price and set up a sell order at a higher price but now I want to cancel it. But can't see it.
Have you tried going to DEX and setting the right pair? The list of your orders for this pair should be shown at "My orders" section. I have just checked and it works in my case.
