  You probably want to elaborate with some code and data. As posted the error speaks for itself: python cannot convert the character " to a float, which is indeed something to be expected.

  Hello,
  My name is Cole and I'm from a startup company based in California that is building a model for automated stock trading. We are examining tick-level data using machine learning tools so that we can begin trading with live feeds using their current capital allocation.

  We are looking to add members to our team!

  Your job as a member of the software team would consist of any of the following duties:

  Performing statistical analysis with libraries such as Matplotlib, scikit, and numpy Constructing/refining models using Tensorflow Using Backtrader to back test models Building trading bots with backtrader Using APIs from Interactive Brokers Building tools in Python for live data feeds Using AWS to manage feeds Using MongoDB

  Please let me know if you have any interest. You can email me at cole@zuluquant.com

  Thank you,
  Cole

  Plotting a vertical line is actually not there, neither on the data nor on the indicator. Your best bets:

  Having an observer plotting markers on the data based on the value of an indicator. The BuySell observer looks into buy/sell orders to plot the markers. This would allow you to plot on the data but would be the most ad-hoc solution.

  Having an indicator plotting markers. For the markers you can look into the BuySell observer or the ParabolicSAR indicator. In your case and since you only want the marker when your indicator is 1, you only assign a value to the indicator when that's the case (and leave the 0 case untouched)

  From BuySell

  plotlines = dict( buy=dict(marker='^', markersize=8.0, color='lime', fillstyle='full', ls=''), sell=dict(marker='v', markersize=8.0, color='red', fillstyle='full', ls='') )

  The marker values and options are defined by matplotlib. See how this Blog - Arrows for the BuySell Observer changes the markers for the BuySell observer

  @backtrader i tried 1.9.57.122 and 1.9.56.122, reverting to a version prior to the funds functionality works.

  Also using stdstats=False works.

  Thanks a lot for your help and this great software.
