Hi jln780,
Please see the comments at the top of your TS code:
// Price Data: Data1: ES.30.Minute.830.1500.CentralUSATime.txt, Data2: idx.30.Minute.830.1500.CentralUSATime.txt, Data3:
spx.30.Minute.830.1500.CentralUSATime.txt
This strategy needs a chart in Tradestation with three graphs namely:
Data1: ES.30.Minute.830.1500.CentralUSATime.txt,
Data2: idx.30.Minute.830.1500.CentralUSATime.txt,
Data3: spx.30.Minute.830.1500.CentralUSATime.txt
