I am trying to set the brick size to ATR at Initilaze for Renko Consolidator but it is given Runtime Error: Attempted to divide by zero. (Open Stacktrace) ? How Cab I assign a ATR as brick size ?
#ATR NAS100USD
self.atrNAS = self.ATR("NAS100USD", 24, MovingAverageType.Simple,Resolution.Hour)
#RENKO NAS100USD
self.brickNAS = self.atrNAS.Current.Value//1
renkoCloseNAS = RenkoConsolidator(self.brickNAS)
renkoCloseNAS.DataConsolidated += self.HandleRenkoCloseNAS
self.SubscriptionManager.AddConsolidator("NAS100USD", renkoCloseNAS)

The stacktrace was not actually linked, so determining the problem will be a little tougher. Is the algorithm warming up the indicator before it is being used? The problem could be that ATR's value is currently 0 at that time. Check the documentation on warming up an algorithm: it pumps data in from before the start date for priming technical indicators, or populating historical data arrays. This sample code warms up an EMA so that it can be using during the start of the algorithm.

def subscribe_renko(self, symbol): if self.renkoInit is False: renkoATR = self.ATR(symbol, 14, MovingAverageType.Simple, Resolution.Hour) self.Log(str(renkoATR.Current.Value) + symbol) renkoClose = RenkoConsolidator(renkoATR.Current.Value) renkoClose.DataConsolidated += self.HandleRenkoClose self.SubscriptionManager.AddConsolidator(symbol, renkoClose) self.renkoInit = TrueSubscribing to the renko consolidator after the init method by calling this function in OnData is a possible solution. I'm still fairly new to QC, it seems like its not possible to access historical data outside of OnData, even with a warmup period. Correct me if I'm wrong.

Historical data can be accessed anywhere within the algorithm using the call self.History(), as long as the data being called has been subscribed. In this example, self.History() is called during Initialize() to manually feed data into the indicators.

atr = AverageTrueRange(14) for index, tradeBar in tradeBarHistory.loc["BTCUSD"].iterrows(): atr.Update(index, tradeBar["close"])I'm using this setup to determine the renko brick size on init, the ATR indicator needs an IBaseDataBar from what I can tell, is there a good way to make that object fromt the rows of the historical dataframe?
