The currency symbol depends directly from the currency of the Betfair Account. Since I have only one account with EUR, I cannot do a real test with a different currency.But I can mock up it, and from my tests the symbol is correctly selected accordingly with the currency of the user. So evidently, there is something else, maybe up to the grid component (it is a third party component 10tec.com/activex-grid/). Like you can see in your last picture, the symbol is correctly shown in the liability in the header of the main window, but not in the grid. Also, the symbol is correctly rendered in the prices columns of the grid (the pink/blu ones) where I append it by my code, but not in the other grid columns where it is rendered using a formatting string. I will contact 10tec to have more info and I will keep you updated.
