Hello,
Thanks for all that can help.
My moving average crossover algorithm is ordering at random times.
It is supposed to buy as 20 day ema passes over 200 day ema( 5 minutes consolidators for each).
However, it orders at times not warranted:
Order # 1 BUY: 2019-12-23 09:40:00 : [200 EMA = 43.46] [ 20EMA = 44.17](this one is kinda ok)
Order # 2 SELL :2019-12-23 15:45:00 : [200 EMA = 44.52] [ 20 EMA = 45.47]
Order # 3: ok
Order # 4 SELL: 2019-12-26 11:50:00 : EMA200 = 45.97--- EMA20=46.87
Order # 5 BUY: 2019-12-26 13:45:00 : EMA200 = 46.01. EMA20 = 46.25
As you can see these are totally random.
Any and all help is appreciated!

Okay. The thing is most of the stuff should be performed in the OnData function. When you program your algo entirely in OnDataConsolidated - it's not exactly what its built for. Please refer to a manual or a bootcamp.
Attached is your working example. But I'm not entirely sure its 100% correct implementation.

Hello... I added 2 lines to show what ema values and prices your code is picking up and it seems the EMA values seem to be incorrect (I am having a very similar issue lol). See the logs section in QuantConnect and compare those values to whatever charting website you use (ex: stockcharts.com, freestockcharts.com). In my 5 minute chart in freestockcharts.com it shows me the EMA200 is under the EMA20 but in QuantConnect logs, the EMA200 is above EMA20... the prices however do seem to be correct.
Not much help, but I am hoping someone can help you out since I am almost on the same boat with some of my ema projects lol

Hi Christian Olsen ,
First of all, thank all of you that tried to help. I know it is not only the Holiday Spirit!
The issue with the algorithm is that the indicators are registered to receive updates twice:
fiveMinuteConsolidator = TradeBarConsolidator(timedelta(minutes=5)) # Here we are subscribing to 1-minute bars self.EMAFAST = self.EMA(self.equity, 20, Resolution.Minute) # Here we are subscribing to 5-minute bars self.RegisterIndicator(self.equity, self.EMAFAST, fiveMinuteConsolidator)So the indicator is updated every minute plus every 5 minutes. Consequently, the value is completely off from what we would expect from either a 1-minute and a 5-minute EMA.
Assuming that we only want to use a 5-minute EMA, we would need to have:
fiveMinuteConsolidator = TradeBarConsolidator(timedelta(minutes=5)) # Here we are creating an indicator without a subscription self.EMAFAST = ExponentialMovingAverage(20) # Here we are subscribing to 5-minute bars self.RegisterIndicator(self.equity, self.EMAFAST, fiveMinuteConsolidator)Please check out the docs, under Indicators, for more details.
