I think TJ had commented long back on the same issue and had said that though its possible to have a feature wherein one can split the bar to have bars of lower time frame than the time frame for which data is available, problem is that since AB doesnt know as to whether the High came first or the Low, the bars will be very misleading to say the least.
Adding artificial bars where data is just arrived at can cause problems in backtesting and optimization in my opinion.

You can't get timeframes lower than the base timeframe. [I say it's an 'implementation issue' because, in something like eSignal, you can get any timeframe you want, regardless of the current one you're in] --- In [email protected], "Peter" <[EMAIL PROTECTED]> wrote: > > I believe you can compress data i.e. if you are using 5 minute data then you > can get anything in a larger timeframe e.g. 6 minute + but you can't go > smaller than the timeframe you are using e.g. 1 minute?? > Peter > > > _____ > > From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf > Of murthysuresh > Sent: Tuesday, 11 September 2007 8:30 p.m. > To: [email protected] > Subject: [amibroker] get 1 minute 9 ema from 5 minute bar > > Hello > i am using 5 minute bars and trying to get the 9 ema of 1 minute bars. > the data returning seems to be incorrect when i compare it visually. > can someone help in pointing out the error. > // i am using 5 minute timeframe and want to see the values of 1 minute > bar. > OneMinuteBars=TimeFrameGetPrice("C",in1Minute,0,expandLast); > " 9 ema at 1 minute bar is " + WriteVal(EMA (OneMinuteBars,9),1.5); // > " 20 ema at 1 minute bar is " + WriteVal(EMA (OneMinuteBars,20),1.5); // > > // trying to use it directly > > //TimeFrameGetPrice(EMA(C,9), in1Minute, 0,expandLast); > //First parameter - pricefield - i > > > __________ NOD32 2520 (20070911) Information __________ > > This message was checked by NOD32 antivirus system. > http://www.eset.com >
