Problem to download some eSignal data

[dalisdj]

Hello,
I got problem with downloading some symbols data from my eSignal OnDemand data source. Specifically Wheat (ZW) and Natural Gas (NG) both daily and minutely. After some experimentations (download data via MultiCharts DT, export, convert into NT format, import) I found that problem is caused by two things.

1. NT has problem if, for example, Open is bigger than High or lower than Low. The same with Close value. What about to do some simple heuristic like
   
   

   If Open > High
   Then Swap(Open, High)

   Same with other combinations.
2. NT has problem with duplicated bars (by same datetime value). Shouldn't be better to rather ignore duplicated bar if values are same for all OHLCV?

Is it the problem of unsuccessful download? In my opinion it is better to try to repair this few broken data than let fall whole download process.
I attach Print Screen of my downloaded NG daily data. ZW is completely empty.

dalisdj,

I am happy to assist you.

It should be impossible for High < Open on the same bar from data sources NinjaTrader can receive through supported connections. If its data in a .csv or other file, then I would say the issue is caused by whatever conversion is being used.

As far as the datetime value, it is possible to have the same time stamp for tick resolution, as time-stamps only have second resolution.

I would humbly suggest reading this in the help guide :

I look forward to helping you solve your issue.
