现货价格是怎么算出来的呢?不同的现货LP有不同的计算方法,但基本是根据期货的价格和合约到期的时间等因素综合计算出来的。例如以下是某LP的现货黄金计算公式 Pricing Algorithm - Formula
P = (TN – T1) / (T2 –T1) * (P2 – P1) + P1
P = Calculated Price
TN = Now
T1 = Expiry date of the previous front future
T2 = Expiry date of the front future
P1 = Price of front future
P2 = Price of next future
P = (Time since previous front month expiry) / (Time between front future andprevious front future) * (Difference in price between front and next future) +front future price
Time used in the actual algorithm is Unix time (e.g. 19-May-2015 00:00:00=1431990000). For simplicity this can be simplified to number of days, as Ihave done in the examples below.
Example
TN = 20/5/2015
T1 = 19/5/2015
T2 = 22/6/2015
P1 = 5852.5
P2 = 5901.5
P = (TN – T1) / (T2 –T1) * (P2 – P1) + P1
P = 1.5 days / 34 days * (5901.5 – 5852.5) + 5852.5
