SElECTINg THE BEST FuTurES PrICE SErIES For SySTEM TESTINg
|
||||
For example, if a trader normally rolls a position over to a new contract approximately 20 days before
|
||||
the last trading day, N would be defined as 20. The scale of the continuous futures series is adjusted so
|
||||
the current price corresponds to a currently traded futures contract.
|
||||
Table 18.1 illustrates the construction of a continuous futures price for the soybean market. For
|
||||
simplicity, this example uses only two contract months, July and November; however, a continuous
|
||||
price could be formed using any number of traded contract months. For example, the continuous futures
|
||||
price could be constructed using the January, March, May, July, August, September, and November
|
||||
soybean contracts.
