BarsRequest

[pjsmith]

Hello,

I am looking to implement BarsRequest in an indicator, so load data from a certain point, for an indicator that does not load a data series. So, I can say, load the data from the last hour, etc. I looked at the code example in the docs, and I can see how I might do this, and how I would process the data. The big question I had, was how would I sync this with the bars of the primary data series on the chart? For example. Main chart is 100 tick, but I request 1 hour of tick data. Is it possible to tell what bunch of ticks from the BarsRequest are in what bar number of the chart data series?

Thanks.

Hello pjsmith,

Below is a link to an example script that does a BarsRequest in an addon (and prints to the output window).

As well as a link to the help guide on BarsRequest which includes example code.

The BarsRequest will not be associated or synchronized with any series or other data.

Hi,

Thanks for the example Chelsea. I'd actually seen this, but it does not answer my question I think.

If I call this in an indicator that already has a primary data series on the chart, how can I find out what bar number of the chart primary data series the current bar of the secondary dynamically loaded data series belongs to? Does that make sense? For example - I have a 1 minute bar series on the chart. I load 15 minutes tick data - I want to mark the bar on the chart where I detect an interesting event in that 15 minutes of tick data. How to I say, OK, I'd on bar 23,567 of the tick set. That happens to be in Bar 5 of the minute set? I hope you get what I am trying to achieve. Thanks.

Hello pjsmith,

BarsRequests will not be synchronized.

You can try using Bars.GetBar() to find a bar in the series by time.

If you need synchronized data, then use AddDataSeries().

Thanks. Adddataseries is what I need to avoid. I will try to fudge something with bars.getbar. I think I can make that work.
