Hey there,
I'm trying to consolidate 500ticks data using TradeBarConsolidator,
using the following reference :
https://github.com/QuantConnect/Lean/blob/master/Algorithm.Python/DataConsolidationAlgorithm.pyI tried to adapt it to futures:
class DynamicCalibratedContainmentField(QCAlgorithm):
def Initialize(self):
self.SetStartDate(2020, 3, 1) # Set Start Date
self.SetEndDate(2020,3,2) #Set End Date
self.SetCash(50000)
ticker = Futures.Indices.NASDAQ100EMini
self.AddFuture(ticker, Resolution.Tick )
#self.ESSMA = self.SMA(futureES.Symbol, 2)
CountConsolidator = TradeBarConsolidator(500)
CountConsolidator.DataConsolidated += self.BarHandler
self.SubscriptionManager.AddConsolidator(ticker, CountConsolidator)
def BarHandler(self, sender, bar):
# With hourly data the bar period is 3-hours
self.Debug(str(bar.EndTime - bar.Time) + " " + bar.ToString())
def OnData(self, data):
'''OnData event is the primary entry point for your algorithm. Each new data point will be pumped in here.
Arguments:
data: Slice object keyed by symbol containing the stock data
'''
for contract in data.FutureChains:
contracts = list(filter(lambda x: x.Expiry > self.Time, contract.Value))
if len(contracts) == 0:
return
self.Debug(f"{self.Time} Last Price: {contracts[0].LastPrice}")Is the following request supported?

Hi Ofir,
To consolidate futures tick data, we first need to select a contract and use the TickConsolidator. We can't consolidate ticks of the canonical symbol.
In Initialize, we write
ticker = Futures.Indices.NASDAQ100EMini future = self.AddFuture(ticker, Resolution.Tick) future.SetFilter(0, 90) self.consolidator_by_symbol = {}Then, in OnData, we select the contract and setup the consolidator. We only setup a consolidator once for each contract we select.
def OnData(self, data): for chain in data.FutureChains: contracts = list(chain.Value) if len(contracts) == 0: continue sortedByOIContracts = sorted(contracts, key=lambda k : k.OpenInterest, reverse=True) contract = sortedByOIContracts[0] if contract.Symbol in self.consolidator_by_symbol: continue CountConsolidator = TickConsolidator(500) CountConsolidator.DataConsolidated += self.BarHandler self.SubscriptionManager.AddConsolidator(contract.Symbol, CountConsolidator) self.consolidator_by_symbol[contract.Symbol] = CountConsolidatorSee the attached backtest for reference.
Best,
