Plotting Indicators
Plot Update Events
To plot all of the values of some indicators, in the Initialize method, call the PlotIndicator 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.AddEquity("SPY")
sma_short = self.SMA(symbol, 10)
sma_long = self.SMA(symbol, 20)
self.PlotIndicator("<chartName>", sma_short, sma_long)
Plot Current Values
To plot the current value of indicators, call the Plot 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.AddEquity("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.PlotIndicators("All Indicator Values", sma, rsi)
self.Plot("Current Indicator Values", sma, rsi);
# Plot indicators that extend the "TradeBarIndicator" type
self.PlotIndicators("All Indicator Values", atr, aroon)
self.Plot("Current Indicator Values", atr, aroon);
If your indicator plots are complex, call the Plot method with one indicator and plot its .Current.Value. For more information about plotting, see Charting.
