Yet some markets are better than others in liquidity, and this is not one of them. Because of that, there are limited number of orders to provide depth due to most orders not meeting the requirements of the centralized quotation market here. On an exchange you have multiple sources including the exchanges themselves that provide liquidity, here it is just the retail customer and the Issuer. The retail customers are limited and unless the broker can internalize the order there isnt much of a market at all in fact the spread here clearly shows there isnt a market here.
