hi. I want to see how to implement a simple Order Imbalance strategy
By Order_Imbalance I mean the ratio between bid volume and ask volume in 5 minute time windows.
And use this indicator to make decisions.

Hi LOB faridi,
We provide bid/ask data through the QuoteBars passed to the OnData method. To track the bid and ask volume over 5 minute windows, we can setup some SMA indicators of length 5 and update them with the bid/ask size each minute.
def Initialize(self): # ... self.bid_volume = SimpleMovingAverage(5) self.ask_volume = SimpleMovingAverage(5) def OnData(self, data): # ... bar = data.QuoteBars[self.symbol] self.bid_volume.Update(self.Time, bar.LastBidSize) self.ask_volume.Update(self.Time, bar.LastAskSize)We can then create a Scheduled Event to calculate the desired ratio and place the trades.
def Initialize(self): # ... self.Schedule.On(self.DateRules.EveryDay(self.symbol), self.TimeRules.Every(timedelta(minutes=5)), self.trade)See the attached backtest for reference.
Best,
Derek Melchin
