createPriceFormatter
Creates a price formatter.
Signature
createPriceFormatter(priceScale?: number, minMove?: number, fractional?: boolean, minMove2?: number, variableMinTick?: string) => IPriceFormatter
Parameters
| Name | Type | Description |
|---|---|---|
| priceScale? | number | defines the number of decimal places. It is 10^number-of-decimal-places. If a price is displayed as 1.01, pricescale is 100; If it is displayed as 1.005, pricescale is 1000. |
| minMove? | number | the amount of price precision steps for 1 tick. For example, since the tick size for U.S. equities is 0.01, minmov is 1. But the price of the E-mini S&P futures contract moves upward or downward by 0.25 increments, so the minmov is 25. |
| fractional? | boolean | for common prices is false or it can be skipped. |
| minMove2? | number | for common prices is 0 or it can be skipped. |
| variableMinTick? | string | for common prices is string (for example, 0.01 10 0.02 25 0.05) or it can be skipped. Example: 1. Typical stock with 0.01 price increment: minmov = 1, pricescale = 100, minmove2 = 0. 2. If minmov = 1, pricescale = 100, minmove2 = 0, variableMinTick = "0.01 10 0.02 25 0.05": - for price = 9: minmov = 1, pricescale = 100, minmove2 = 0. - for price = 13: minmov = 2, pricescale = 100, minmove2 = 0. - for price = 27: minmov = 5, pricescale = 100, minmove2 = 0.
