Hi, I'm also a user of QuoteTracker Range candlesticks, and miss the feature in AmiBroker. There is an entry in the Feedback Center, with a couple comments, so the developer(s) know about our feature request.
I've tried my hand at coding a Range Bar chart display, but it has the following problems: a) The choice of range bar size determines the number of bars displayed on the screen - too large a range, and only part of the screen will have bars, too small a range, and there are too many bars to fit in an array, so not all the price data can be processed. b) If the database time interval is too large, you can't use small ranges. First, there will be few range bars, and second, it is not possible to tell, when processing large time-interval bars, whether the range bars should go up first to the high, then down to the low, or vice versa. So the time interval must be small, and then the range must also be small. It is tough to get a combination that works well, and fills the screen. c) The range bars are mapped to the times of the source time interval price bars, and so it is hard to tell when the range bar was created. This may be possible with some more programming work, but it might still be tough to get a date and time scale on the chart. d) Indicators don't apply to range bars, so you have to create your own indicators (and use the range bar arrays as input). So, the conclusion I've come to is that the AmiBroker program will need to support range bars natively, as it currently supports time and tick bars, especially for backtesting and scanning to work. BTW, if anyone else has attacked this problem with good results, please let us know. - Bill --- In [email protected], "ib_ferra1" <[EMAIL PROTECTED]> wrote: > > Hi all > > im italian trader > > i don't know if u have never seen QUOTETRACKER...... in quotetracker > there's one charts type, Range Candlestick, that there isn't in > Amibroker...... > > I want have Range chart on amibroker, but im not enougth good in AFL > and i'haven't find nothing of similar on web > > Thx for help > Bye > > Ferra >
