@FaiqS said in Multiple Datafeeds and multiple Timeframes:

Which is not convenient to iterate through in next function of strategy.

It may not be convenient for you. Don't mix them in such a way then. Add first the lower timeframes and later the higher timeframes. You will have two clear partitions.

Or iterate using steps other than 1 and with different starting indices.

@FaiqS said in Multiple Datafeeds and multiple Timeframes:

The straightforward it is referring to is to add "cerebro.adddata(data)"

No. It is referring to resampledata(data, ...). Using any other approach won't change the order in which things are in the system and where.

1. It's not an issue and the article doesn't say so. It says that people tend to believe it is an issue but it is lack of understanding.

2. You are NOT getting duplicate records. But you fail to show what you print, so it is virtually impossible to say what you are printing.

3. When a data feed moves past other and the "other" has no new records only the existing price can be shown.

4. Data feeds (and mostly everything) has a len to indicate if something new has been added. Check the len.

Lines do only store floats. Nothing prevents that you store more complicated structures as member attributes of your indicator.

Some people tend to name the script backtrader.py and end up importing the script and not the package.

any advice?

Yes. Search ... https://community.backtrader.com/topic/2016/basic-plotting-no-x-axis

FIRST LESSON IN ALGOTRADING (believe me when I say it is an important one)

In algotrading like in chess, look carefully at what's right before your eyes, like what's at the top of every page of this community.

For code/output blocks: Use ``` (aka backtick or grave accent) in a single line before and after the block. See: http://commonmark.org/help/

2nd, this thread says (one example)

@backtrader said in Plotting only chosen data?:

@run-out said in Plotting only chosen data?:

You do this by setting plot=False when creating your dataline.

This can be done at anytime, not only during creation.

The same can be read in the documentation here: https://www.backtrader.com/docu/plotting/plotting/

Where are you doing that in your code which seems fairly incomplete? (Actually for any of the data, you have many and only 2 are shown)

You are not even storing the resampled data instance in a variable to do that

Nobody is interested in your secret sauce. If you want to show something and hide your very profitable code, create a 10 line snippet to show the problem.

Let us see what you do ... to find out why you cannot.

The default configuration can be switched off when running cerebro.run with the parameter stdstats.

After that you can add your own plethora of observers, including the BuySell one and decide where you want the markers
