Forget time, watch action
Range Bars are determined for alternate price charting. Unlike the usual time frame chart – where every candle represents a fixed time interval – the goal is to ignore time and to display price movement using candles with equal heights.

Unique Features
What are additional features of Ovo offline generators?
- the generator is an indicator rather than a script or EA, which makes it more comfortable for deployment
- input setting is adjustable from multiple places: from the input dialogue, or from the entry box of an indicator sub-window, or from the offline chart using additional indicators (Omnia Remote, Omnia Auto Range). Settings on the offline chart makes the range switching as flexible as switching between timeframes.
- safe timeframe switching of the feed chart (no need for sacrificing the feed chart for a single timeframe)
- generator can detect and optionally break chart into trading sessions
- generator uses all available timeframes for the initial model, and it is not bound to a single selected timeframe
- when starting up, the indicator selects the chart starting anchor from the user-defined chart candles count
- a single indicator can serve multiple identical offline charts (a single chart ID in multiple windows)
- detects significant drop-outs in feed and rebuilds the offline chart after the feed updates
- displays consistent candle tick volume calibrated to regular timeframes, so you may rely on the tick volume in your analysis and EAs
- guards for a change of the feed server, so it updates the chart if you switch between accounts
- works properly with symbols having MQL unfriendly names (like “EURUSD..”, i.e. trailing double dot in the name)
- reports unexpected time gaps in the MT4 history, reports inconsistencies between symbol timeframes
- excludes phantom (no volume) ticks
- fixes incorrect input for a non-trivial instrument tick size
- can decrease chart refresh rate on demand
- indicator development is still open, you may expect fast fixes for new Metatrader builds

Hi Theo,
I prefer to configure my charts only one time. I would like to close metatrader 4 platform after trading for a few hours. Every time I open metatrader 4, do I have to reload the range bar indicator again to start collecting data from beginning all over or will it update from earlier data and resume from the previous range bar.
Neither of the two. The indicator recalculates all over, but uses previously recorded tick data, so the candlesticks shape is identical like it was in the live session. Only the candlestick chart lenght may be trimmed on the left to fit the initial input settings.
Is it a scripts need to be manually loaded every time MT4 is started, or an indicator who can be left on the charts & will start automatically with MT4 ?
Hello Michel, it is an indicator, so it sticks to the chart until removed.
Sorry, I was taking about the rang bar one !
What am I doing wrong?–When I clicked the download box to get the Original Range Bars, I got a pop-up box that says, “Adobe Reader could not open ‘RangeBar.ex4’ because it is either not a supported file type or because the file has been damaged…” I am very much looking forward to your product. Please pardon my general basic computer illiteracy.
Hello Mark, you may try to rightclick the link and use the “Save link as” option to prevent a browser extension opening the download.
Hi Theo
I am running EURUSD; Standard 5M chart; Excellent internet connection; Number of offline candles = 600; I am having issues where ONLY the OVO Range Bar Chart becomes laggy and then just freezes. Would this problem resolve the moment I move from an OVO demo to an OVO paid/licensed account?
Thanks

Hello Jas, there is no difference between trial and licensed use of the indicator, you will encounter the same behaviour. However this behaviour is not typical and you may use the contact form for describing your problem with additional helpful data or screenshots and environment description (versions of Windows, MT4 etc.)
Hello , this is Andy
I am interested in Range Bar code
Does it compile to MT4?
Hello Andy, the product is a compiled indicator for MT4. In case you meant the source code, it is not supplied with the product. In case you meant code for the license, you may proceed to the http://ovo.cz/order-key/ page.
This is Andy again
Thank you for your reply.
I have download the trial version.
Thanks God , it does run smoothly.
Does it mean the range bar.ex4 will run smooth in the life time version ?
Hello Andy, there is only a single version for both trial and licensed period. The license purchase unlocks time restriction.
This is Andy again
I have just have a look to the comment posted by other people
I have got some questions:
1) what is the difference between ” Range Bar ” and Range no Gap Bar” ?
2) what is the best configuration of my PC/ version of MT4 can help your software give the best performance?
3) MT4 will automatically update itself. Can you software compile to the most updated version of MT4 ? or I need to do something ahead?
Million Thanks
1. The former respects the original range bars definition, the latter drops down the 1-tick gap rule.
2. The load caused by the generator alone is constant, but other indicators attached to offline chart might perform better when you keep the offline chart short.
3. You cannot recompile the indicator yourself, but downloading the latest version solves such problems.
regarding to your reply no.3
“”downloading the latest version solves such problem””
Do you mean downloading the latest version of your software ?
If yes ,
do I need to pay again to downloading it ? (given that I have paid for the life license of Range bar already )
or latest version of MT4 ?
Given :
MY PC windows is WINDOW 7
MT4 version is Build 940
Hi,
I would like to buy Range bar generator for forex trading. Could you please advice the price. I see that $45 for 3 months for three user profiles. Is that correct? Does 3 user profile mean 3 computers?
Please advice, if there are any offers. Does buying more than 1 license cost less?
Please advice.
I successfully downloaded the range bar but where can I input the code?
Hello Kazuki,
please enter it into the indicator input entry:
I am a range bar trader who has primarily traded Futures using the NT Platform and have been looking into Forex with the MT4 Platform. This is a wonderful indicator! Thank you! I love it but I do have 1 suggestion you might want to consider:
(1) To the right of the current bar have 2 horizontal lines 1 above and 1 below showing where the current bar will open and close. In addition, I have the price to the right of the horizontal lines.
This is of tremendous help to me as a price action trader. Below is a pic of what I had programmed for my NT Range Bars:

Hi
Can I trade from the Range Bar Chart? And can I attach an EA to it and have it function correctly. What does OFFLINE chart mean?
Yes, you may trade and run the EA. The wording “offline chart” stands for a chart, which is not directly maintained by the MT4 feed. You might understand it as “custom”.
Is the auto range software still available? I don’t see the download for it. That would be a very helpful tool.
ooops…found it
Ok, its loaded….but the original feeder chart has big and little bars and fills up new ones while scrolling. And the offline bar has equal sized bars but no new ones are drawing. The USD/JPY has moved about 30 pips and no new bar……hmm.
I’ve watched the video twice but evidently I’m missing something.
Hi I have just purchased you Range Bar indicator, I am using it on Dax index however in the morning when the market opens with a gap up or gap down the gap is shown as a series of green or red range bars is there anyway we can sort this out so that the offline chart shows the real gap and starts the bars from there?
Hello Hos, change the Session parameter either in inputs or by the OmniaRemote GUI.
Thank you sorted out
Hi just downloaded your range bar ea and would love to finally purchase it but using trial in the mean time, it says valid till September 2nd, two questions is this midnight of September 2nd 00:00 or sometime during the day or midnight of September 3rd, 2nd question is with the purchase I can use it for life on any computer right?
The trial time is calculated precisely since the moment of the first indicator use.
The license is lifetime, you may migrate it from a computer to a computer and use it on three computers concurrently.
Hello,
Does anyone have the same issue on Range bar chart?
A part from all benefit of range bar chart, I came a cross with any object when you draw them on the chart, they wont be stay stable and by opening a new candle all the object and trend lines mess up and you have to redraw them again which is really annoying.
Is there any solution for it?
Thnaks
Do not place control points of objects in the area of the blank part of the chart (the future). The scale on the left-hand side is defined by the range bars, while on the right-hand side by the chart timeframe. The time scales are incompatible between those parts.
Thanks a lot, problem solved.
