  • A

    Hi!, i am newat backtrader, i have read all documentation and fin any information related but i dont know how to change thebuy and sell markers distance to the data when i plot the results with .plot() . I am using 1 minute data and this markers are to far to the data and i cant see it easily. Can anyone help me with this? Many thanks!

    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

    An example

    Thank you for your answer,

    The first thing I apologize, I think I did not know how to put the code well.

    The second my code is not secret, its only a test. I put only the backtest running parts because there are too many lines.

    I read the documentation before post and had no problem hiding the imported data directly. My problem is that I don't know how to hide daily resampled data in the chart. Perhaps i lose something but I really can't find anything about it. Here I show everything:

    Many thanks for the answer. I cant find how can i change the buysell observer params. How can i do it? I tried this but the params didnt work.

    class MyBuySell(bt.observers.BuySell):
    
    params = (('barplot', True), ('bardist', 0.0))
    
    plotlines = dict(
        buy=dict(marker='$\u21E7$', markersize=4.0),
        sell=dict(marker='$\u21E9$', markersize=4.0)
    )
