FXCM - Ninja or FXCM server and why ?

[After]

Hi everybody,

I would like to backtest a forex system but I have an issue : FXCM data from FXCM server and FXCM data from Ninja server are different. Which one is the right one ? Which one I would have in live ?

Thanks a lot !

After,

Live data is going to be coming from FXCM. The server you are choosing is for Historical data.

I would recommend using the NinjaTrader servers as they will have more historical data available going further back.

Thanks Cal, but between these two options historical data are differents. As a result, my backtest result is different. Which option is the right one ? Should I trust backtest result from FXCM server or Ninjatrader server ?

Hello After,

Thank you for your response.

What variations are you seeing and with what instruments, dates and data types (Day, Minute, and Tick)?

As we talk about FXCM (forex) data, I can see differences with every forex cross.

If we take a candle from FXCM - FXCM server, and the same candle from FXCM - Ninja server, we have a different high/low/open/close.

Differences are very small, we have to open the data box to well see them. But it's enough to modify trade signal from my system and change my backtest result.

So I wonder which one I should trust, which one I would have in live..

What version of NinjaTrader are you using? You can check under Help -> About (Example: 7.0.1000.X)

Hello After,

Thank you for your response.

Can you provide an example of the data being different? The data should be the same.
