I don't think it adjusts contracts internally. I meant it won't read
an arbitrary file of data like TradeStation does. For example:
With TS, you can have a data file with any name. NinjaTrader forces
a naming convention on you. For futures, it wants the name to have
a contract month and year. This is meaningless for futures data, and
makes it impractical to use NinjaTrader with the files from data
services such as Pinnacle.
With TS, you can use standard comma-delimited text files. NinjaTrader
wants everything to be space-delimited. That isn't standard, and it's
impractical to expect me to convert all my files to fit that format.
With TS, you get many choices about what data columns your file
can contain. It can have just date and value, or date, high, low,
close, or other combinations. NinjaTrader requires you to have
date/time, open, high, low, close, and volume. No more, no less.
No open interest. No capability to read in, say, daily spot prices
(date and close).
In my opinion, the inflexibility regarding user's data is the
biggest drawback to NinjaTrader. On the plus side, it can retrieve
stock history from Yahoo (limited to a few hundred bars), and
futures history from IB. But if you rely on other services for
historical data, you're screwed.
