Study/Price Overlay Study vs. Moving Average - Time Period Study

Hi,

I have an intraday chart that needs to plot a daily moving average. I have found two different ways to do so in SC.

1. Study/Price Overlay Study referencing a Moving Average on a Daily chart.
2. Moving Average - Time Period Study with Time Period input set to Days.

However the values plotted by each one these methods are significantly different from each other. Why is that?

There is certainly going to be a difference. Moving Average - Time Period Study will be most accurate.

One thing to check would be the Session Times for the Intraday chart. What are they set to?

Session times on intraday chart (15min) are as follows:

Regular Start: 08:30:00
Regular End: 16:00:00

Evening Start: 17:00:00
Evening End: 08:29:59

Can you please tell me the reason for the difference? Also why do you suggest that Moving Average - Time Period Study will be more accurate? Looking back at the ES charts (continuous contract), the difference can get pretty big at times.

TIA.

Those are the right session times. Explaining the reason for the difference is well outside the scope of our support. This is just simply involved. And you really should be able to understand the reasons anyway. And we really cannot even answer it anyway because we do not know precisely how you are using those studies and what the chart data is.

I really don’t think that I’m asking for anything outside the scope of support. There are two studies that SC provides; at least on the surface it seems like they should be doing the same thing, but as I have pointed out that there are significant differences in their values. Personally, I think that there’s a bug in the Moving Average - Time Period study, but before I jump to that conclusion, I want to give you a chance to explain the difference.

I should be able to understand reasons for the difference? If I did, why do you think I would be wasting your time and mine on this support ticket?

As far as how I’m using the studies or what the chart data is, I have done my best to explain both of those. If you need further clarification, please feel free to ask.

This will take some time. We just have to make sure that we have documented the study properly and double check the calculations. Allow about a week.

One of the programmers is looking at this, and it needs further review. We hope to finalize it this week.

I just began looking for ways to address exactly this, and also am very much looking forward to more information. In my case I believe the unexpected results I'm seeing are because I am plotting a time-based MA onto a Renko chart, and so there are sudden crazy moves in the MA from periods of time that the MA is not taking into account (sessions are closed, long periods of time with little price action, etc.).

I will be keeping an eye on this thread for sure.

We apologize for the delay. One of the programmers who was looking at this, had some other things they had to do and we got behind with reviewing this.

We did carefully examine Moving Average-Time Period. The study function definitely works correctly as it is designed. But it may not really always be doing what you might think.

We did some updates to the documentation and you can review the updated information here:
https://www.sierrachart.com/index.php?page=doc/StudiesReference.php&ID=439&Name=Moving_Average_-_Time_Period

So decide whether it meets your requirements or not. If not, do not use it.

I appreciate you updating the documentation. Unfortunately I'm not really able to follow the technical explanation. It's clearly written by a developer with that audience in mind. Maybe another user can translate it.

I read the updated documentation, but I’m still not clear on why there’s a difference in Studay Overlay and Moving Average - Time Period study.
