I've recently subscribed to CSI data & I'm just getting my head around the amount of configuaration options that are available. I've noticed that on a lot of the futures contracts there are options for both day, and 24 hours data. Which data would I be best using to calculate with my trading - 24 hour or day? I'm trading a trend following system, using end of day data. The OHLC numbers are quite radically different, and as such I'm sure would alter the expectancy of the system. Thanks in advance J-s
