Hi, The file for SPY-NQTV.dly has an error on 2026-02-02 The OHLC is wrong for the Low of the day. Either by a factor of 10, or a misprint. Another feed has the low of the day for the SPY as 689.42 Not sure if this is an error on your side or theirs. Cheers |

This is actually a value which has been transmitted by the CTA data feed. So it is an error from the actual source, from the industry data feed. We deleted the low of the day record with this invalid value, but apparently it exists somewhere else and this is very hard for us to track down. We might just manually correct the value in the daily file. In any case, this will take a little time. Sierra Chart Support - Engineering Level Your definitive source for support.

There are multiple invalid daily low values from the exchange on that date, that we have to clean up: Line 42440: 2026-02-13 23:38:45.732 | 2026-02-02 16:15:00.042210, DAILY_SETTLEMENT, Date=2026-02-02, FloatValue=695.41, VolumeValue=0 Line 42441: 2026-02-13 23:38:45.732 | 2026-02-02 16:15:00.042211, DAILY_HIGH, Date=2026-02-02, FloatValue=696.93, VolumeValue=0 Line 42442: 2026-02-13 23:38:45.732 | 2026-02-02 16:15:00.042212, DAILY_LOW, Date=2026-02-02, FloatValue=69.005, VolumeValue=0 Line 42443: 2026-02-13 23:38:45.732 | 2026-02-02 16:15:00.042213, DAILY_VOLUME, Date=2026-02-02, FloatValue=0, VolumeValue=77975410 Line 42444: 2026-02-13 23:38:45.735 | 2026-02-02 17:05:00.042177, DAILY_SETTLEMENT, Date=2026-02-02, FloatValue=695.41, VolumeValue=0 Line 42445: 2026-02-13 23:38:45.735 | 2026-02-02 17:05:00.042178, DAILY_HIGH, Date=2026-02-02, FloatValue=696.93, VolumeValue=0 Line 42446: 2026-02-13 23:38:45.735 | 2026-02-02 17:05:00.042179, DAILY_LOW, Date=2026-02-02, FloatValue=69.005, VolumeValue=0 Line 42447: 2026-02-13 23:38:45.735 | 2026-02-02 17:05:00.042180, DAILY_VOLUME, Date=2026-02-02, FloatValue=0, VolumeValue=78642877 Line 42448: 2026-02-13 23:38:45.737 | 2026-02-02 18:40:00.045382, DAILY_SETTLEMENT, Date=2026-02-02, FloatValue=695.41, VolumeValue=0 Line 42449: 2026-02-13 23:38:45.737 | 2026-02-02 18:40:00.045383, DAILY_HIGH, Date=2026-02-02, FloatValue=696.93, VolumeValue=0 Line 42450: 2026-02-13 23:38:45.737 | 2026-02-02 18:40:00.045384, DAILY_LOW, Date=2026-02-02, FloatValue=69.005, VolumeValue=0 Line 42451: 2026-02-13 23:38:45.737 | 2026-02-02 18:40:00.045385, DAILY_VOLUME, Date=2026-02-02, FloatValue=0, VolumeValue=79120414 Line 42452: 2026-02-13 23:38:45.738 | 2026-02-02 20:04:00.043966, DAILY_SETTLEMENT, Date=2026-02-02, FloatValue=695.41, VolumeValue=0 Line 42453: 2026-02-13 23:38:45.738 | 2026-02-02 20:04:00.043967, DAILY_HIGH, Date=2026-02-02, FloatValue=696.93, VolumeValue=0 Line 42454: 2026-02-13 23:38:45.738 | 2026-02-02 20:04:00.043968, DAILY_LOW, Date=2026-02-02, FloatValue=69.005, VolumeValue=0 Line 42455: 2026-02-13 23:38:45.738 | 2026-02-02 20:04:00.043969, DAILY_VOLUME, Date=2026-02-02, FloatValue=0, VolumeValue=79286521 Sierra Chart Support - Engineering Level Your definitive source for support.
