I was switched from DTN to QUODD on 12/3/2018. That's when I realized a raft of necessary data was not provided. Most importantly this includes dividends, splits, and prior close adjusted for ex-dividends and splits. Today, 12/4/2018, the exchange a trade executed on was frequently missing (set to 0). My first take is that this affected NYSE and ARCA executions on NYSE/ARCA listed stocks. For me, this made the data feed unusable and I suppressed new trade entries. It also created issues exiting from existing trades. Just what you want on a day the SPY fell 3.22%. The switch from DTN to QUODD was first announced seven months ago. I have no confidence they will get this resolved in a timely manner. I will have to shut down trading until these issues are fixed or I find an acceptable alternative. Is anyone aware of a data feed matching NxCore's completeness and quality when it was using DTN?
