Hi all,

I'm trying to create RangeBars of 3 points from the IQFeed's data however although I have some great success like creating RangeBars that matches what I see in charts on eSignal(eSignal data) and Ninja Trader (IQFeed Data) 99% of the time, what I cannot understand is that even with Ninja Trader, I'm having different results.

For example, looking at YM Futures, December 2011 for the 4th of October 2011 at approximately 10:43:16 to 10:43:27, with my calculations I would have had about 9x RangeBars of 3 points. This includes 2 phantom ticks that I added to close the RangeBar at either it's High value or Low.

However, when checking against eSignal and Ninja Trader, and as stated above, Ninja Trader is using IQFeed as it's data source, both have considerably less bars, like only 5 and eSignal had only 4??????? What is going on??? because this is completely throwing off ALL of my Technical Analysis calculations.

From what I understand about RangeBars, there are 3 conditions that needs to be met.

Quoted from the link below
http://www.investopedia.com/articles/trading/10/range-bar-charts-different-view.asp#axzz1a0szcxmC


Three rules of range bars:

Each range bar must have a high/low range that equals the specified range.
Each range bar must open outside the high/low range of the previous bar.
Each range bar must close at either its high or its low.

Can anyone help me figure out what I am doing wrong please?

Look at the attached screen shot. The green highlighted columns signify matching values to eSignals charts and Ninja Trader sorta matches up. The rest just simply don't match up.

HELP!!!!!

Thanks

David
