[ECO Bounty] iopay Price Display Issue for WMTX in xStocks

Description: The ioPay wallet is failing to display the market price and total value for the WMTX asset under the xStocks tab. While other assets in the list are displaying price changes and values correctly, WMTX shows as "$ --".

Steps to Reproduce:

1. Open the ioPay mobile application.

2. Navigate to the Wallet tab.

3. Select the xStocks category at the top of the asset list.

4. Scroll down to the WMTX ticker.

Expected Result: The app should display the current market price of WMTX, the 24h percentage change, and the USD value of the user's holdings (even if the balance is 0).

Actual Result: The price and asset value fields display as "$ --", indicating a data retrieval error or missing price feed for this specific ticker.
