Nasdaq OMX said yesterday that it had signed a five-year agreement with the Abu Dhabi Securities Exchange to continue providing trading technology to the Middle-Eastern market, the latest in a string of technology deals for the US-headquartered exchange operator.

The ADX, which already operates Nasdaq technology, has agreed to upgrade to Nasdaq OMX's X-stream multi-asset technology platform for equities, fixed income and exchange traded funds by the second half of next year.
