Donchian indicator issues

Hey,

I'm having difficulties using the DCH indicator. 

self.fast_btc = self.DCH("BTCUSD", fast_period, Resolution.Minute)

The error is: "Failed to initialize algorithm: Initialize(): Python.Runtime.PythonException: NotSupportedException : DonchianChannel does not support Update(DateTime, decimal) method overload. Use Update(IBaseDataBar) instead."

I haven't been able to find any documendation on IBaseDataBar. What do?

T.Y.!

Update Backtest








do you update the indicator in the code with the update method?

.update(bar.Time, bar.Price)

you need the bar itself i think
