Hey Harsh,
We can use a RollingWindow to store the 2 most recent bars. We can update our rolling window each time a new 30-minute bar is available. This is done easily by using the DataConsolidated event handler for our 30-minute consolidator.
# Define and Register Consolidator
thirtyMinuteConsolidator = TradeBarConsolidator(timedelta(minutes=30))
self.SubscriptionManager.AddConsolidator(self.spy, thirtyMinuteConsolidator)
# Set DataConsolidated Event Handler, each time a new bar is available the OnThirtyMinuteBar method will be called
thirtyMinuteConsolidator.DataConsolidated += self.OnThirtyMinuteBar
# Define Rolling Window
self.barWindow = RollingWindow[TradeBar](2)
And in our event handler method, we can add our bar to our rolling window and also access the previous bar.

def OnThirtyMinuteBar(self, sender, bar):
self.barWindow.Add(bar)
if not self.barWindow.IsReady:
return
currentBar = self.barWindow[0]
previousBar = self.barWindow[1] To plot a time series, we can use the self.Plot(chart_name, series_name, value) method.
self.Plot("My Custom Chart", "High", High)
self.Plot("My Custom Chart", "Low", Low)
Learn more about plotting in the documentation.
THank you for the above,it cleared my doubts
in addition, i need to place an order by comparring the close of 2 consolidation of 30 min each.
for example
if currentbar.close>previousbar.high:
setholding("SKY",1)
elif currentbar.close<previousbar.low:
setholding("SKY",0)
the above if else statement should run only once that too at 10:30(based on the current bar and previous bar) only..
and if there is any buying took place at 10:30,sell all of them at end of that day only.
I tried but am getting same result even if i chage the timming.Please help
Hi Harsh,
You can use scheduled events to fire code at specific times of the day. For example,
self.Schedule.On(self.DateRules.EveryDay("SPY"), self.TimeRules.BeforeMarketClose("SPY", 1), self.ClosePositions)This creates a scheduled event which fires our method ClosePositions everyday 1 minute before market close. Learn more about scheduled events in the documentation.
Best
Rahul
