Dear the SEC,

When did Latency Arbitrage go from "that doesn't happen" to "it doesn't happen anymore" to "Latency Arbitrage must be allowed"? Those who submitted negative comments are all basically saying that IEX will kill Latency Arbitrage and therefore IEX should not be allowed to be an exchange.

Approve IEX.

Cheers
