· | As published: This choice provides charts with the actual open, high, low and settlement, even when the settlement is outside the trading range. When the settlement committee decides, after the close, that the settlement should be at a level where no trading occurred, charts can show a no-trading gap between the actual high/low bar and outlier settlement price.
|
· | Modify High/Low (the default, for a typical open-high-low-close bar): This choice makes the close price (settlement) fall within the high/low range by adjusting the range. It produces charts with possible adjustments to highs and lows when the settlement is outside the trading range. A traditional open, high, low, close bar chart results. By taking this choice, you may produce an artificial trading range, which includes an area where no trading occurred.
|
· | Modify Close: This choice makes the close price (settlement) fall within the high/low range by changing out-of-range settlements. It produces charts where the closes (settlements) may be modified if the settlement price lies outside the daily trading range. In the event that the settlement lies outside of the high-low range, the settlement may be adjusted to match the high or low which is closest to its value. This technique ignores the settlement price, but preserves an accurate view of the market's trading range. Settlement accounting users would not obtain an accurate view of a portfolio's value using this choice.
