There is bad overnight data in the SC feed for SPY. Price ranges from $40 to >$400. Can data provider correct this?

We will be cleaning this up, this evening.

This is from our data provider:

The NYSE / AMEX primary production had a meltdown yesterday, so they had to bring up their disaster recovery site to send data. They ended up extending the trading session beyond the usual closing time - and to accommodate we removed our time checks for the feed which block messages after regular closing. We also did this as we hoped they would resend the official end of day summary message later in the evening - which apparently they did not do.

Anything after 8:15pm ET last night from these exchanges should be purged, or you can re-pull from our historical system which does not have these issues.

We will be adding back our time checks after market today.
