cAlgo Error CS1503 with AverageTrueRange Indicator (ATR)

I'm encountering a CS1503 error in my cAlgo robot when trying to calculate the Average True Range (ATR) indicator. The error message indicates that I'm providing incorrect argument types to the Indicators.AverageTrueRange() method.

Here's the relevant code snippet:

indicatorTasks.Add(Task.Run(() =>
    indicators[timeframe][symbol]["ATR"] = Indicators.AverageTrueRange(
        bars, config.IndicatorSettings.ATR.Period)));

Error Messages:

• CS1503: Argument 1: cannot convert from 'cAlgo.API.Bars' to 'int'
• CS1503: Argument 2: cannot convert from 'int' to 'cAlgo.API.MovingAverageType'

Context:

• I'm using cAlgo in Ctrader 5.0.50
• I'm trying to calculate the ATR indicator for multiple symbols and timeframes.
• The bars variable is a Bars object obtained using MarketData.GetBars(timeframe, symbol).
• config.IndicatorSettings.ATR.Period is an integer representing the ATR period.

Troubleshooting Steps Taken:

• I've double-checked the cAlgo API documentation to confirm the arguments for AverageTrueRange.
• I've verified that the bars variable is a valid Bars object and the Period is an integer.

Question:

Any idea why am I getting these CS1503 errors with the AverageTrueRange indicator? What am I doing wrong, and how can I fix this issue?

Many thanks for your help!
