The range bars are all wrong. The open price of a bar should always be 1 pip above or below the previous bar's close unless the market has gapped. In JForex new bars open on the next quarter hour at the then current price, irrespective of where the last bar closed. (The purpose of range bars is to be time independent.)

This is a pretty big bug. Can someone please look at it?

Thanks.

I think you're interpretation might be a bit wrong.

The opening price of a bar is above or below the previous bar's close,
but that is not by 1 Pip. I'd say it would be by 1 Pipette ( or 1/10th Pip),
which corresponds to the minimum price movement.

With higher pricing resolution, successive bars' price ranges can be
very similar. One an up bar, the next a down bar, with the difference
between the opening of the next bar versus the close of the previous
bar being quite a small price delta.

Having said this, I really don't use them, so I could be wrong...
