Instruments that trade in quarter- and half-thirty-seconds can be confusing. Sometimes they are quoted with a plus sign at the end of the price. For example, you might see a price quoted as,
10003+
What this means is, 100 and 3 half thirty-seconds. The plus sign at the end of the quote denotes the four in the fraction 4/8. To get half-thirty-seconds, Aspen Graphics multiplies 3/32 by 4/8 and then reduces the fraction to get a value equivalent to 64ths, or 1/2 32nds. When you type a half thirty second, omit the plus sign. You type,
100'034
For an instrument quoted in quarter-thirty-seconds, Aspen Graphics might give you the following quote,
10005+
This means 100 and 5 quarter-thirty-seconds. Here, the plus sign denotes the 2 in the fraction 2/8. To get quarter-thirty-seconds, Aspen Graphics multiplies 5/32 by 2/8 and reduces the product to get a value equivalent to 128ths, or 1/4 32nds. Again, when you enter a quarter-thirty-seconds price in the trigger condition field, you type:
100'052
The numerator at the end of the price (the 4 in the first example and the 2 in the second example) is more specific than the plus sign. Although prices shown by Aspen Graphics can have plus signs, you cannot use the plus sign in alarms, formulas, account watch windows, and when editing bad ticks. If Aspen Graphics is displaying prices, it inserts the plus sign. If you are entering a price by hand, you need to specify half- and quarter-thirty-seconds using the numerator convention.
