@DmitryVil The fix should be already there (since 1.18.450). Let us know if that doesn’t help.

This was a market order and for market orders the price and cost always returns zero because you could have filled different prices with your market order. Use fetchMyTrades to find the prices and costs for your executed market order and build the average of it.
