The recently-approved IEX exchange from US is providing its market data free of charge.
Since the ever rising cost of the market data is a contentious issue in the trading community, this should be a welcome development.
The question is, how long these data will remain free ?
Initially, BATS US exchange’s was also free of charge. In 2013, as soon as the exchange has captured sufficient market share, the charges were introduced, although to be fair, BATS pricing policy is still more
attractive in some aspects than NYSE’s and NASDAQ’s.
IEX’s market share is currently less than 2% - not insignificant, but still much behind the established exchanges.
Providing their market data for free might be a good marketing strategy for them, but it remains to be seen if they will continue to do so once their market share goes above 5%.
