Support alternative data series with ohlc info

[pjsmith]

Hi,

I have an indicator that makes bars. It works perfectly on the primary (default) data series, as you would expect. On a chart with 2 data series, if I change the input series of the indicator to the second data series, it no longer works properly.

Can you point me to docs / provide a hint of code changes required to support the second data series? For info, the second data series is just an alternative time of the primary. It is a data series from the instrument, not another indicator input.

I hope this makes sense.

Thanks.

Do you have an example that you can attach?

Hello pjsmith,

Thank you for your post.

When you use the secondary series as the input, does the indicator still calculate and just display differently than you'd expect, or does it give you an error, either on screen or in the Log tab of the Control Center?

I agree with bltdavid, we'd really need an example of the code. Would you have an example script you could attach to your reply? You can remove any code unnecessary to replicate the issue.

Thanks in advance; I look forward to assisting you further.

it does not display as expected. To get the highs, lows, etc., I am using this in OnBarUpdate

HAOpen[0] = Open[0];
HAHigh[0] = High[0];
HALow[0] = Low[0];
HAClose[0] = Close[0];

This works fine with default or single data series. When I add a second data series and try to use that as the input series, it no longer works as expected. This should work? There are no obvious issues doing this? Thanks.

Hello pjsmith,

From the added details its really not clear what may cause that, we would likely need a example indicator that you can attach so we can test that.

Its also not clear what is not displaying correctly, you mentioned it makes bars. Is it doing some custom plotting to make bars or is this a bar plot? An image of the expected vs difference could help here also.

If you want to do a simple test you could try using a simple indicator like the SMA and do the same steps for applying it to see if that produces a problem. That would help weed out any problems in the manual steps you are doing if any.

Please let us know if we may be of further assistance.

Did you try,

HAOpen[0] = Opens[0][0];
HAHigh[0] = Highs[0][0];
HALow[0] = Lows[0][0];
HAClose[0] = Closes[0][0];

A second DataSeries in code is not a BarsArray, it will not provide OHLC values when used as an input series.

Thank you muchly - No, I did not. But, I just did, and it seems to be working. Thanks for responding. Really appreciate it.
