odd chart times

is there a way to get a chart with a 3h bar or an 8h bar?

I can go through and paint them on the chart but then i cant test on them very well

thank for any help

You can create the charts with Period_converter script and open the charts, attach indicators to it and all that but the chart won't update (or maybe it does update if you keep the script running?). I think that EA backtesting in a simple way will not work but I proabably could work around it too if it is possible in MT4 at all.
