[ Lean Engine - Report Creator - Local Development ]: Adding custom charts with custom data to the local backtesting report

Back

I am new to QuantConnect's Lean engine and I am backtesting a strategy locally.

On the website IDE platform I am able to chart custom charts - the price chart, indicators, etc. - but when I run it locally, it does not work and only appears the strategy performance.

If I open the backtesting data file (locally), there is nothing there regarding the custom charts.

 

I've created the charts with this info:

https://www.quantconnect.com/docs/algorithm-reference/charting

 

It works on the online platform, but not locally. I tried searching for info here (but to no avail):

https://www.quantconnect.com/tutorials/open-source/lean-report-creator

 

Is there a way of accomplishing this?

Or do I need to create my own frontend to display this data?

 

Here's an example:

public class Strategy : QCAlgorithm
{
public override void Initialize()
{
Chart stockPlot = new Chart( "Trade Plot" );
Series assetPrice = new Series( "Price", SeriesType.Line, "$", Color.Blue );
stockPlot.AddSeries( assetPrice );
Series buyOrders = new Series( "Buy", SeriesType.Scatter, "$", Color.Green, ScatterMarkerSymbol.Triangle );
stockPlot.AddSeries( buyOrders );
Series sellOrders = new Series( "Sell", SeriesType.Scatter, "$", Color.Red, ScatterMarkerSymbol.TriangleDown );
stockPlot.AddSeries( sellOrders );

AddChart( stockPlot );

// (...)
}

public void OneHourHandler(object sender, TradeBar tradeBar)
{
Plot( "Trade Plot", "Price", tradeBar.Close );
Plot( "Trade Plot", "Buy", tradeBar.Close );

// (...)
}
}

Hey JOÃO,

The custom chart data can be found in the result json file, which is located at Lean/Launcher/bin/Debug/Strategy.json. You can retrieve the chart information from the file and plot it using matplotlib or another charting library.
