Plotting Indicators
Plot Update Events
To plot all of the values of some indicators, in the Initializeinitialize method, call the PlotIndicatorplot_indicator method. The method plots each indicator value as the indicator updates. The method accepts up to four indicators.
var symbol = AddEquity("SPY");
var smaShort = SMA(symbol, 10);
var smaLong = SMA(symbol, 20);
PlotIndicator("<chartName>", smaShort, smaLong) symbol = self.add_equity("SPY")
sma_short = self.sma(symbol, 10)
sma_long = self.sma(symbol, 20)
self.plot_indicator("<chartName>", sma_short, sma_long)
Plot Current Values
To plot the current value of indicators, call the Plotplot method. The method accepts up to four indicators.
// In Initialize
var symbol = AddEquity("SPY");
var smaShort = SMA(symbol, 10);
var smaLong = SMA(symbol, 20);
// In OnData
Plot("<chartName>", smaShort, smaLong) # In Initialize
symbol = self.add_equity("SPY")
sma_short = self.sma(symbol, 10)
sma_long = self.sma(symbol, 20)
# In OnData
self.plot("<chartName>", sma_short, sma_long)
View Charts
The following table describes where you can access your charts, depending on how to deploy your algorithms:
| Location | Algorithm Lab Algorithms | CLI Cloud Algorithms | CLI Local Algorithms |
|---|---|---|---|
| Backtest results page |  | | |
| Live results page | | | |
| /backtests/read endpoint | | | |
| /live/read endpoint | | | |
| ReadBacktest method | | | |
| ReadLiveAlgorithm method | | | |
| Local JSON file in your <projectName> / backtests / <timestamp> or <projectName> / live / <timestamp> directory | | |
Chart Limits
Not all indicators share the same base type(T), so you may not be able to plot them together since some indicators require points while others require TradeBars.
// Plot indicators that extend the "Indicator" type
PlotIndicators("All Indicator Values", sma, rsi);
Plot("Current Indicator Values", sma, rsi);
// Plot indicators that extend the "TradeBarIndicator" type
PlotIndicators("All Indicator Values", atr, aroon);
Plot("Current Indicator Values", atr, aroon); # Plot indicators that extend the "Indicator" type
self.plot_indicators("All Indicator Values", sma, rsi)
self.plot("Current Indicator Values", sma, rsi);
# Plot indicators that extend the "TradeBarIndicator" type
self.plot_indicators("All Indicator Values", atr, aroon)
self.plot("Current Indicator Values", atr, aroon);
If your indicator plots are complex, call the Plotplot method with one indicator and plot its Current.Valuecurrent.value property. For more information about plotting, see Charting.
