I've had an ongoing problem when using the Difference Indicator (bars) or the Overlay OHLC indicator. For some reason, the current bar will repaint portions of the candle that have already printed. For example, if price spikes and then retraces back to the original location, there is no wick showing. I've tried everything and read the How to create highly accurate spread charts etc. But for some reason I don't know why this keeps happening. Neither one of these indicators seem to print bars like a normal chart where it tracks price and it prints statically on the chart and stays put. Any help is appreciated.

When using the Study Overlay - OHLC study, what is the timeframe of the chart bars for the chart the study is referencing?

The Study Overlay - OHLC is referencing 10 Second bars. I followed the exact instructions from the Creating Highly Accurate Spread Charts page. I created it using the Difference (single line) as the instructions suggested and it doesn't work. Then I switched to the Difference (Bar) and the problems still occurs.

Try reducing the source chart to 1 second bars. But you are going to want only load a very small number of days in that chart so there are not too many chart bars in that chart. Refer to: http://www.sierrachart.com/index.php?page=doc/ChartSettings.html Longer-term we will add the capability to perform simple calculations like this at a lower level to avoid having to use the method that you currently are. Probably sometime next year. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

Thanks, but I've had this problem even when going down as low as 1 second. 1 second may increase the resolution/granularity of the chart, but it still does not explain why the bar will repaint and disappear without showing any wicks. The bars are not showing correct information. If a bar reaches a certain price, and retraces, that portion of the bar should remain painted up to that price (static). But this doesn't happen; it disappears. Try it out for yourself and you will see what I'm referring to. Thanks again.

The only other thing that would help is to change the chart down to 1 Number of Trades per Bar: http://www.sierrachart.com/index.php?page=doc/ChartSettings.html#TimePeriodPerBar Before the end of the year we will have a look at the capability to create custom spread symbols. We will see if we can get that released for general purpose use like this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Thanks for considering creating a custom spread capability. Since spread/pair/stat arb trading is very common, it would be a useful feature. I'm curious if you add that feature, will it fix the bar repaint problem?

Yes.

Hello, I'm just following up on my earlier post above to check on the status of things. I'm currently having a similar problem with the Sum Charts From Lists study also. Was just curious if this has been fixed or if there are plans to in the near future. Thanks again.

Custom spread symbol support is not available right now. We hope to get to it this year. But it is not something to wait around for.

I'm following up once again on the issue mentioned above from last year to check the status. My entire trading strategy revolves around using your various Difference, Sum all charts, and Spread 4 indicators, etc. Unfortunately for me I can't use the software until this is fixed. Can you please explain why this occurs and what the cause of this issue is? Because it is impossible to analyze symbols if the live data retraces/disappears and is not printing or retaining most of the bar's visual information on the chart (see attached screenshot). One additional note that may be helpful. The problem doesn't seem to be about creating custom spread symbols as you mentioned above. For example the Spread 4 Indicator seems to be fine the way it is set up for inputting various symbols. Instead, the problem is the way the actual chart functions and prints the data. Live data bars retrace and do not print the wicks of the bar so most of the bar's dynamic range is missing; making the bar incomplete. If you logout and log back in, those same bars will show the full dynamic range. Thanks again. Any response is appreciated because I can't trade without this one issue being resolved.

The capability for customs symbols now exists. Can you just tell us the exact spread symbols and the overall formula and we will tell you the symbol to use and the necessary Symbol Settings. These customs symbols can only create chart data from the real-time data. There is no historical data created other than from what is recorded in real-time. So you need to keep Sierra Chart running. In regards to the problem you describe in the post above, we do not know why you would have that issue but we would like to know what the timeframe of the bars in those charts is. But all you need to do is just select Chart >> Recalculate if there is a problem with the study result. Sierra Chart Support - Engineering Level Your definitive source for support.

I am trading a variety of commodity symbols using the Spread 4 indicator. The custom symbols capability really isn't the issue and doesn't apply here. My main problem is when using any type of Spread or Difference indicator, the historical and real time data are treated differently somehow. In answer to your question, I have used various bar times from 1 second up to 15 minutes and the same problem occurs regardless of the underlying time frame used. If you test out any of your Spread or Difference indicators, you will see for yourself how it reacts to incoming data (as my screenshot shows). Watch the current bar and how it will retrace and not print the entire price history. The entire bar will also disappear and reappear during price spikes.

The custom symbols capability really isn't the issue and doesn't apply here. We do not know how you come to this conclusion. The new feature we have added which is not yet documented, is exactly what you want. We will write up documentation for this and provide a link in the next few days.Watch the current bar and how it will retrace and not print the entire price history. This is expected when using a study like the Difference (Bar) study and is documented. What we would not expect and something we could never reproduce, is where when recalculate the chart, you are seeing a different result at historical bars created during real-time updating from a study like the Difference (Bar) study. So there must be something more complex that you are doing that we cannot see because you are providing an extremely narrow and hidden context of what you are doing. So in essence what you are showing us is next to useless. In any case one thing came to mind about about studies referencing other charts like the Difference (Bar) study that we want to improve upon and we will do that but we do not think that is related to the core issue you are having.

Ok, maybe I am not understanding how the new Custom Symbols works and how it will be helpful, but I will wait for the documentation to see how to properly implement it and the virtues of its use. Sorry if my example seem narrow, but I provided a simple screenshot just to give you an idea of what I am seeing. But what I am doing is very straightforward. I open an new chartbook, I add four charts with different symbols and I use the Spread 4 Indicator to create a spread from those four charts. The resulting output is what you saw in my screenshot. That's as strait forward as it gets. The only additional thing I can think of that I'm doing is I added the BAAVG suffix to the end of each symbol. But I have this issue with or without the BAAVG suffix. When you say "this is expected when using a study like the Difference (Bar) study and is documented." Can you explain what you mean by that and show me where I can read more documentation about why this is happening? Are you saying it is normal for the current bar to retrace like that? |

Would having a version of the Spread 4 indicator as a Line on Close help with the bar issue?

No, that will not help. Just wait for the documentation. We should have it today or tomorrow.

If you don't mind, when you have a moment could you please explain how the Custom Spread Symbol will fix the bar retrace problem? I'm sorry, but I'm just not understanding how that will rectify the problem. Thanks.

We are going to put out the documentation for that no later than the end of the day tomorrow and once you use it, you will see it will work as you require.

Hi, I have two questions after reading the documentation. 1. How would you input the symbols for various commodity contracts that have different months/years etc? 2. How do you obtain the BAAVG/midpoint data for these custom symbols? Does that have to be written into the formula in some way? Truly accurate spread charts should be based on the bid/ask midpoint instead of the Last price otherwise the charts will be severely inaccurate. I'm wondering how to accomplish this with the custom symbol. |

1. Just use the actual symbol in the formula. This is all. For example ESZ18. 2. Just use the actual symbol in the formula as you normally do. Just simply append -BAAVG Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

So just to be clear, in your example I would input for example {ESZ18-BAAVG}-{ESV18-BAAVG}?

Just tried Feb-Oct CL Spread but I get error messages. {CLG19-NYMEX-BAAVG}-{CLV19-NYMEX-BAAVG} Can you tell me what's wrong with this formula? Thanks.

FYI, I know you don't like for people to respond with thank you notes because it clogs up your system, but I just wanted to say thank you SO SO much for adding this custom symbol capability! Once I finally get it working it will definitely add a whole new dimension to SC allowing users to plot unlimited symbol models while also allowing the ability to use all of the various chart types available, other than just line and bar spread/difference studies. Thanks again!
