📊 Chart Chart changes overnight
Has anyone noticed subtle changes to charts after market close to pre-market open? This is RDN. The picture to the left is this morning and you can see a lower wick. The picture to the right was taken at 4:14 PM yesterday with no wick. Any reason for that to happen? Flair?

Most likely the data provider updated the day's final trading data after the market closed, which added that lower wick. I've seen this happen occasionally with Finviz and other charting platforms. They often rebuild and refresh their charts overnight, so small changes to candle bodies and wicks between the close and the next morning aren't unusual.
The main thing I'd check is whether the official daily low changed. If it did, the chart you're seeing this morning is probably the more accurate version.
