Chart differences

[vast524]

I am wondering why this happens.
I open x2 1min charts with Zenfire feed
I have MACD and Eco running as my indicators.
They will be slightly different on each chart.
I can understand if I am running Volume or Tick charts. But using the same feed and a time based chart I would have thought that they would be the same.
I sync the PC clock before opening Ninja as well.
It seems to do it on all my markets. ES, TF, STOXX...
Can anyone please explain how this happens.

Zen-Fire does not support historical data. It retrieves the historical data from our historical data server. There can be a difference in the historical data and the real-time data, since they are retrieved from two seperate sources.

I suspect the two charts do not have the same historical/real-time data proportion, which could explain the small difference.

I suggest to right click in both charts and select 'Reload Historical Data', so both charts will load all historical data from one source.

Thanks for the reply.
I am using the charts live though.
Not backtesting.

Hello vast524,

My response is referring to live charts.

I wonder why though after refreshing historical data that if I do it again 5 mins later the drawn indicators will be different again.
This is quite frustrating and a worry.
Is there a reason for this please.

The source for historical data and real-time data with Zen-Fire is not the same. Different sources can have discrepancies.

If you reload historical data after 5 minutes, the last 5 minutes will be retrieved from our historical data server, while it was initially retrieved from Zen-Fire in real-time.

So, I should not be refreshing data then?
Or only at the start of opening 2 charts showing the same data and time frame.
So I guess the zenfire feed is more accurate than the historical data?
It seems a lot worse on the Stoxx (FESX) than the US charts.
Could there be a reason for this?

If you would like the charts to contain the same data, you will need to ensure the historical/real-time data proportion is equal; open two new charts or reload historical data at the same time.

I am not sure why there is more discrepancy in regards to the FESX.
