Plotting - candlestick charts and highlighting economic/news events



  • Hi, is it possible to plot the chart as a candlestick/bar chart instead of a line chart?

    Another question, I am trying to incorporate economic events/data into Backtrader. Any suggestions on how to feed the events into Backtrader, and is it possible to highlight bars where major data has been released? Thanks!

    There are some tens of samples plotting candlesticks and/or bars.

    Check here for the option style when plotting: Docs - Plotting

    You can extend a data feed to have extra data Docs - Extending a Data Feed which can be the P/E ratio like in that case or anything you like.

    To Plot the events the best options would be:

    • Creating an Indicator that only delivers a point when an economic event happens. Assign the high or the low and plot and arrow/triangle or other marker

    • The same but with an Observer. In this blog post, the triangles of the BuySell observer are changed to arrows Blog - Arrows for the BuySell Observer

      Your best option is to check the source for the BuySell observer or the Trades observer and plot the economic events instead of the operations/trades.
