DataSeries data discrepancy

[lawrence124]

Hi, I've a strategy which use multi-instruments and i will but a dataseries like this, say

CloseDiff.Set( Closes[0][0]*2-Closes[1][0]*1); (time frames are the same)

the problem is, strategy is triggered by instrument #0 by end of bar but seems like end of bar of instrument #1 has not been triggered, ie, the calculation was completely off in real-time

when I load the strategy again (using Print statement so i can know what is going on step by step), there wont be any problem as all the bars were built properly

how to prevent the data/bar discrepancy in real time? Thanks

lawrence124, that could be the case in realtime - as NT is an event driven framework, the missing update from instrument 2 for example could mean the calculation is running with the last known tick only.

I would recommend looking into KDoren's spread indicator works from the sharing, it's offering a concept to sync datapoints as in your case needed as well -
