custom time frames???

hi there,im lookin for a way to set up some custom time frames,e.g.90 min,10min etc,can anyone help ??
i have tried the custom candle indicator but it is not quite what i want.is it possible to simply set different time frames for new charts/?
thanx in advance

periodcon is the only one that I know of that will let you do custom timeframes. Otherwise, you are stuck with the default ones in MT4.
