When I place an order on the EU Volatility Index, a message pops up saying "Order level too close to market level. The order level you have requested is too close to the current market level".
I do understand what this means, however, what I don't understand is how this has suddenly changed. Before yesterday I was able to place an order as close as I liked to the current price. Now I can't do this and orders have to be too far away from the current price.
