Range Bar Chart
The example stated are for illustrative purpose only, and should not be viewed as advice or guarantee of performance.
The range bars just look price, the bar does not close at a specific time but closes when a range is complete, then a new bar opens.
If you have a market that moves from 1 to 9, then 9 to 1, then 1 to 9 during 2 days, if you create a range bar chart of $10 you will only have a bar that goes from 1 to 9 during these 2 days and this bars is not closed. If the market moves to 10 then the bar closes and a new bar opens with open price at 10. This new bar now must have $10 range to close. Letís say the market goes back to 6 and then up to 17, the last range bar closes at 16 (making a range bar from 6 to 16) a new bar opens with open price at 16 and this bars price is now 17. This new bar has now a range of $1 (16 to 17) and will wait until a complete $10 range to close.
This is interesting in a market in congestion; you can have days with no new bar opening, the next picture shows IBM in a 78 minute chart and in a $2.50 range bar chart.
Note that from 9/12 to 9/18 the regular 78 minute chart has 16 bars while the $2.5 range bar has just 2.
Note that the range bar chart (bottom chart) has an arrow on the last bar, that shows that the last bar still open waiting to be completed, while the top chart 78 minutes does not have the arrow anymore, that bar is closed.
The program has 2 ways to create Range Bars charts.
The first way uses the 1 minute bar data to create the range bar, then these range bars have some limitations.
A very small range, that is smaller than a normal range of a 1 minute bar will create problems. In real time the program will create more than 1 range bar on the same minute, but when recreating the bars this information does not exist.
Lets say the market moves in 1 minute from 1 to 3, then 3 to 1, then 1 to 3, if you create a range bar of $1.00 in real time as the market moves you will see, 2 bars for the first move from 1 to 3, then 2 bars more for the move from 3 to 1 and then 2 bars more for the move from 1 to 3, total of 6 range bars in 1 minute.
As you close the chart and reopen it, or as the chart is rebuilt, the information from the same 1 minute bar is only a market that had a low of 1 and a high of 3, with close at 3. The program will look to this 1 minute bar and will recreate just 2 bars, one bar from 1 to 2 and one bar from 2 to 3. This chart will then be different of what actually happen in real time.
Then we recommend that you have the ranges values bigger than the oscillation of the 1 minute bars.
To create a range bar check the box Range Bar, type the range you want on the R$ box. Next and highest period are fixed on daily and weekly.
The second way uses tick data to create the bars (version R46 or later).
Small ranges will be OK as the chart will use tick information.
create a Range Bar chart using tick data check the Range Bar checkbox and
the Use Tick Data checkbox.
