Inconsistent prints on T&S from different data providers

[rezamerik]

Hi there!

I've noticed my Rithmic data (real brokerage account) and NinjaTrader Continuum (demo account) show different prints on the tape! For example, the prints from Rithmic data that are shown as "ABOVE ASK", are printed as "AT ASK" when I'm connected to NinjaTrader Continuum.

Why is this happening? Should they not be the same? Which one should I trust (I suppose Rithmic because it's the real account?)?

Thanks!

Hello rezamerik,

Please note that you can experience differences in data between different data sources. See the link below.

Discrepancies Between Different Data Feeds
Different data feeds produce different charts, especially when using tick based intervals vs time based intervals. Market data vendors each employ various methods for tick filtering, throttling and time stamping. As a result, no data stream is 100% identical and thus can cause subtle differences in charts. Since NinjaTrader supports many of the leading brokerage and data feed technologies, it is highly likely that two traders using NinjaTrader on different data feeds will have minor differences when plotting the same market and time interval.
